    BPA proposes to fund a project that will enhance in-stream habitat within the Upper Salmon River watershed through a program of irrigation system improvements. The proposed improvements include consolidation and improvement of diversions, installation of headgates to control diversion flow, installation of pipes to reduce conveyance loss of water, and installation of fish screens or infiltration pipes to exclude fish from irrigation canals. These conservation measures will enhance riparian habitat by contributing to instream flows in the project area, which includes Champion, Iron, Fourth of July and Goat Creeks.

    The accomplishments of the John Day, Umatilla, and Walla Walla Fish Passage and Screening Programs include the following: Operation and maintenance of 364 existing fish screening devices (see Table 4), replacement of 18 outdated fish screening devices that totaled 31 rotary drums (some were multiple drum systems), 4 new screens at unscreened diversions, 26 pump intake fish screens, fabrication of components for 16 additional fish screens for the Rogue basin, construction of two fish passage structures, and participation in other activities. After the replacement or construction of 22 fish screening devices during 2001, we now have 108 screening devices that meet NMFS criteria. Funding for these projects was attained from BPA, NMFS and OWEB. The John Day Fish Passage and Screening Program focused construction efforts into new and replacement fish screening devices for these various programs throughout the state of Oregon. The program also continued to develop and implement innovative designs to meet the diverse and expanding needs for the state of Oregon. Projects completed during this report period meet the current National Marine Fisheries Service (NMFS) criteria. Fish species targeted for protection include ESA Listed Mid-Columbia steelhead, Columbia basin bull trout, anadromous and resident salmonids, and numerous non-game fish species. Priority project locations have been identified as the upper reaches of the Middle Fork, North Fork, South Fork and the Mainstem of the John Day River and their tributaries. These upper reaches contain critical salmon and steelhead spawning and rearing habitat.

    advise of allowable fish consumption from specific water bodies. The geometric mean Hg concentration of 10 fish of a single species collected from a single water body (lake or stream) in Idaho is compared to the action level to determine if a fish consumption advisory should be issued. The U.S. Geological Survey collected and analyzed individual fillets of mountain whitefish (Prosopium williamsoni), smallmouth bass (Micropterus dolomieu), and channel catfish (Ictalurus punctatus) for Hg. The median Hg concentration of 0.32 mg/kg exceeded the Idaho water-quality criterion at the site in Brownlee Reservoir. Average Hg concentrations from Brownlee Reservoir (0.32 mg/kg) and the Boise River at mouth (0.33 mg/kg) exceeded the Hg RPTE threshold (>0.24 mg/kg). IFCAP action levels also were exceeded at the sites on Brownlee Reservoir and at the mouth of the Boise River. Median Hg concentrations in fish at the remaining four river sites were less than 0.20 mg/kg with average concentrations ranging from 0.14 to 0.21 mg/kg Hg. Selenium (Se) analysis also was conducted on one composite fish tissue sample per site to screen for general concentrations and to provide information for future risk assessments. Concentrations of Se ranged from 0.07 to 0.49 mg/kg wet weight; average concentrations were highest in smallmouth bass (0.40 mg/kg) and lowest in mountain whitefish (0.12 mg/kg).

    Understanding the effects of irrigation diversions on populations of Pacific lampreyLampetra tridentata in the Columbia River basin is needed for their recovery. We tested the effectiveness of five common fish screen materials for excluding lamprey ammocoetes: interlock (IL), vertical bar (VB), perforated plate (PP), and 12-gauge and 14-gauge wire cloth (WC12) and (WC14). When fish (28–153 mm) were exposed for 60 min to screen panels perpendicular to an approach velocity of 12 cm/s in a recirculating flume, the percentage of ammocoetes entrained (i.e., passed through the screen) was 26% for the IL, 18% for the PP, 33% for the VB, 62% for the WC14, and 65% for the WC12 screens. For all screens, most fish were entrained within the first 15–20 min. Fish length significantly influenced entrainment, with the PP, VB, and IL screens preventing fish greater than 50–65 mm from entrainment and the WC14 and WC12 screens preventing entrainment of fish greater than 90–110 mm. Fish of all sizes repeatedly became impinged (i.e., contacting the screen for more than 1 s) on the screens, with the frequency of impingement events increasing during the first 5 min and becoming relatively stable thereafter. Impingement ranges were highest on the IL screen (36–62%), lowest on the WC14 and WC12 screens (13–31%), and intermediate on the PP and VB screens (23–54%). However, the WC14 and WC12 screens had fewer and larger fish remaining as time elapsed because so many were entrained. For all screen types, injuries were rare and minor, and no fish died after overnight posttest holding. Our results indicate that wire cloth screens should be replaced, where practical, with perforated plate, vertical bar, or interlocking bar screens to reduce lamprey entrainment at water diversions.

    Petrosky, Charles E.; Holubetz, Terry B.

    1987-11-01

    The Idaho Department of Fish and Game (IDFG) has been conducting an evaluation of existing and proposed habitat improvement projects for anadromous fish in the Clearwater River and Salmon River drainages over the last 3 years. Projects included in the evaluation are funded by or proposed for funding by the Bonneville Power Administration (BPA) under the Northwest Power Planning Act as off-site mitigation for downstream hydropower development on the Snake and Columbia rivers. This evaluation project is also funded under the same authority. A mitigation record is being developed to use increased smolt production (i.e., yield) at full-seeding as the best measure of benefit from a habitat enhancement project. Determination of full benefit from a project depends on completion or maturation of the project and presence of adequate numbers of fish to document actual increases in fish production. The depressed nature of upriver anadromous stocks have precluded measuring full benefits of any habitat enhancement project in Idaho. Partial benefit will be credited to the mitigation record in the interim period of run restoration.

  12. Fish communities and related environmental conditions of the lower Boise River, southwestern Idaho, 1974-2004

    2006-01-01

    Within the last century, the lower Boise River has been transformed from a meandering, braided, gravel-bed river that supported large runs of salmon to a channelized, regulated, urban river that provides flood control and irrigation water to more than 1,200 square miles of land. An understanding of the current status of the river's fish communities and related environmental conditions is important to support the ongoing management of the Boise River. Therefore, fish community data from the U.S. Geological Survey and the Idaho Department of Fish and Game collected since 1974 were analyzed to describe the status of fish communities in the lower Boise River. Each set of data was collected to address different study objectives, but is combined here to provide an overall distribution of fish in the lower Boise River over the last 30 years. Twenty-two species of fish in 7 families have been identified in the lower Boise River-3 salmonidae, trout and whitefish; 2 cottidae, sculpins; 3 catostomidae, suckers; 7 cyprinidae, minnows; 4 centrarchidae, sunfish; 2 ictaluridae, catfish; and 1 cobitidae, loach. Analysis of fish community data using an Index of Biotic Integrity (IBI) for Northwest rivers shows a decrease in the biotic integrity in a downstream direction, with the lowest IBI near the mouth of the Boise River. The number of tolerant and introduced fish were greater in the lower reaches of the river. Changes in land use, habitat, and water quality, as well as regulated streamflow have affected the lower Boise River fish community. IBI scores were negatively correlated with maximum instantaneous water temperature, specific conductance, and suspended sediment; as well as the basin land-use metrics, area of developed land, impervious surface area, and the number of major diversions upstream of a site. Fish communities in the upstream reaches were dominated by piscivorous fish, whereas the downstream reaches were dominated by tolerant, omnivorous fish. The percentage of

    Hunting, fishing, and recreational rates of 276 American Indians attending a festival at Fort Hall, near the Idaho National Engineering and Environmental Laboratory (INEEL), were examined. Nearly half of the sample lived on the Fort Hall Reservation, and half were American Indians from elsewhere in the western United States. An additional 44 White people attending the festival were also interviewed. The hypothesis that there are differences in hunting, fishing, and recreational rates as a function of tribal affiliation, educational level, gender, and age was examined. Information on hunting and fishing rates are central for understanding potential exposure scenarios for American Indians if the Department of Energy`s INEEL lands are ever opened to public access, and the data are important because of the existence of tribal treaties that govern the legal and cultural rights of the Shoshone-Bannock regarding INEEL lands. Variations in hunting, fishing, and photography rates were explained by tribal affiliation (except fishing), gender, age, and schooling. Hunting rates were significantly higher for Indians (both those living on Fort Hall and others) than Whites. Men engaged in significantly higher rates of outdoor activities than women (except for photography). Potential and current hunting and fishing on and adjacent to INEEL was more similar among the local Whites and Fort Hall Indians than between these two groups and other American Indians.

    In the summer and fall of 2001 the Pacific Northwest National Laboratory (PNNL) evaluated 23 Phase II fish screen sites in the Yakima River Basin as part of a multi-year study for the Bonneville Power Administration (BPA) on the effectiveness of fish screening devices. Data were collected to determine if velocities in front of the screens and in the bypasses met current National Marine Fisheries Service (NMFS) criteria to promote safe and timely fish passage and whether bypass outfall conditions allowed fish to safely return to the river. Based on our studies in 2001, we concluded that: in general, water velocity conditions at the screen sites met fish passage criteria set forth by the NMFS; most facilities efficiently protected juvenile fish from entrainment, impingement, or migration delay; automated cleaning brushes generally functioned properly; chains and other moving parts were well greased and operative; and removal of sediment build-up and accumulated leafy and woody debris are areas that continue to improve. Continued periodic screen evaluations will increase the effectiveness of screen operation and maintenance practices by confirming the effectiveness (or ineffectiveness) of screen operating procedures at individual sites. Where procedures are being followed and problems still occur, evaluation results can be used to suggest means to better protect fish at screening facilities. There has been a progressive improvement in the maintenance and effectiveness of fish screen facilities in the Yakima River Basin during the last several years, in part, as a result of regular screen evaluations and the rapid feedback of information necessary to improve operations and design of these important fish protection devices. Continued periodic screen evaluations will increase the effectiveness of screen operation and maintenance practices by confirming the effectiveness (or ineffectiveness) of screen operating procedures at individual sites.

    This project is necessary to insure that replacement of fish screening devices and fishways meet current NMFS design criteria for the protection of all salmonid life stages. The mission of the fish passage program in Northeast Oregon is to protect and enhance fish populations by assisting private landowners, public landowners, irrigation districts and others by maintaining fish screening devices and fishways. These facilities reduce or eliminate fish loss associated with irrigation withdrawals, and as a result insure fish populations are maintained for enjoyment by present and future generations. Assistance is provided through state and federal programs. This can range from basic technical advice to detailed construction, fabrication and maintenance of screening and passage facilities. John Day screens personnel identified 50 sites for fish screen replacement, and one fish passage project. These sites are located in critical spawning, rearing and migration areas for spring chinook, summer steelhead and bull trout. All projects were designed and implemented to meet current NMFS criteria. It is necessary to have a large number of sites identified due to changes in weather, landowner cooperation and access issues that come up as we try and implement our goal of 21 completed projects.

    In 2002, the Pacific Northwest National Laboratory evaluated 23 Phase II fish screen sites in the Yakima River Basin as part of a multi-year project for the Bonneville Power Administration on the effectiveness of fish screening devices. Pacific Northwest National Laboratory collected data to determine whether velocities in front of the screens and in the bypasses met National Marine Fisheries Service criteria to promote safe and timely fish passage and whether bypass outfall conditions allowed fish to safely return to the river. In addition, Pacific Northwest National Laboratory conducted underwater video surveys to evaluate the environmental and operational conditions of the screen sites with respect to fish passage. Based on evaluations in 2002, PNNL concluded that: (1) In general, water velocity conditions at the screen sites met fish passage criteria set by the National Marine Fisheries Service. (2) Conditions at most facilities would be expected to provide for safe juvenile fish passage. (3) Conditions at some facilities indicate that operation and/or maintenance should be modified to increase safe juvenile fish passage. (4) Automated cleaning brushes generally functioned properly; chains and other moving parts were typically well greased and operative. (5) Removal of sediment buildup and accumulated leafy and woody debris should be improved at some sites.

    The Snake River is the tenth longest river in the United States, extending 1,667 km from its origin in Yellowstone National Park in western Wyoming to its union with the Columbia River at Pasco, Washington. Historically, the main-stem Snake River upstream from the Hells Canyon Complex supported at least 26 native fish species, including anadromous stocks of Chinook salmon Oncorhynchus tshawytscha, steelhead O. mykiss, Pacific lamprey Lampetra tridentata, and white sturgeon Acipenser transmontanus. Of these anadromous species, only the white sturgeon remains in the Snake River between the Hells Canyon Complex and Shoshone Falls. Today, much of the Snake River has been transformed into a river with numerous impoundments and flow diversions, increased pollutant loads, and elevated water temperatures. Current (1993-2002) fish assemblage collections from 15 sites along the Snake River and Henrys Fork contained 35 fish species, including 16 alien species. Many of these alien species such as catfish (Ictaluridae), carp (Cyprinidae), and sunfish (Centrarchidae) are adapted for warmwater impounded habitats. Currently, the Snake River supports 19 native species. An index of biotic integrity (IBI), developed to evaluate large rivers in the Northwest, was used to evaluate recent (1993-2002) fish collections from the Snake River and Henrys Fork in southern Idaho and western Wyoming. Index of biotic integrity site scores and component metrics revealed a decline in biotic integrity from upstream to downstream in both the Snake River and Henrys Fork. Two distinct groups of sites were evident that correspond to a range of IBI scores-an upper Snake River and Henrys Fork group with relatively high biotic integrity (mean IBI scores of 46-84) and a lower Snake River group with low biotic integrity (mean IBI scores of 10-29). Sites located in the lower Snake River exhibited fish assemblages that reflect poor-quality habitat where coldwater and sensitive species are rare or absent, and

    Pacific Northwest National Laboratory evaluated Gardena Farms, Little Walla Walla, and Garden City/Lowden II Phase II fish screen facilities and provided underwater videography beneath a leaking rubber dam in the Walla Walla River basin in 2006. Evaluations of the fish screen facilities took place in early May 2006, when juvenile salmonids are generally outmigrating. At the Gardena Farms site, extended high river levels caused accumulations of debris and sediment in the forebay. This debris covered parts of the bottom drum seals, which could lead to early deterioration of the seals and drum screen. Approach velocities were excessive at the upstream corners of most of the drums, leading to 14% of the total approach velocities exceeding 0.4 feet per second (ft/s). Consequently, the approach velocities did not meet National Marine Fisheries Service (NMFS) design criteria guidelines for juvenile fish screens. The Little Walla Walla site was found to be in good condition, with all approach, sweep, and bypass velocities within NMFS criteria. Sediment buildup was minor and did not affect the effectiveness of the screens. At Garden City/Lowden II, 94% of approach velocities met NMFS criteria of 0.4 ft/s at any time. Sweep velocities increased toward the fish ladder. The air-burst mechanism appears to keep large debris off the screens, although it does not prevent algae and periphyton from growing on the screen face, especially near the bottom of the screens. In August 2006, the Gardena Farm Irrigation District personnel requested that we look for a leak beneath the inflatable rubber dam at the Garden City/Lowden II site that was preventing water movement through the fish ladder. Using our underwater video equipment, we were able to find a gap in the sheet piling beneath the dam. Erosion of the riverbed was occurring around this gap, allowing water and cobbles to move beneath the dam. The construction engineers and irrigation district staff were able to use the video

    The Fish Creek Reservoir quadrangle in south-central Idaho lies on the north-central margin of the Cenozoic Snake River Plain at the southern end of the Pioneer Mountains. Rocks exposed in the quadrangle range in age from Paleozoic through Cenozoic. Mesozoic rocks are absent. Though Triassic and Jurassic sedimentary rocks may have been deposited in this area, they have been removed by erosion following uplift and thrusting of the Late Cretaceous to early Tertiary Sevier orogeny. The Late Devonian to Early Mississippian Antler orogeny preceded the Sevier. Ordovician through Devonian rocks of western-derived shale and sandstone facies and eastern carbonate shelf facies are unconformably overlain respectively by Pennsylvanian-Permian Wood River and Mississippian Copper Basin Formations. These two sequences are exposed in structural windows juxtaposed by the Sevier-age Pioneer thrust fault. Interpretive cross-sections accompany the map. Volcanic rocks of the Eocene Challis Volcanic Group, Miocene Idavada Volcanics, and Pleistocene Snake River Group cover parts of the area that remains tectonically active.

    The goal of this report is to document current production practices for hatcheries which rear anadromous fish in the Columbia River Basin and to identify those facilities where production can be increased. A total of 85 hatchery and satellite facilities operated by the Idaho Department of Fish and Game, Oregon Department of Fish and Game, US Fish and Wildlife Service, Washington Department of Wildlife, and Washington Department of Fisheries were evaluated. The years 1985 to 1987 were used in this evaluation. During those years, releases averaged 143,306,596 smolts weighing 7,693,589 pounds. A total of 48 hatchery or satellite facilities were identified as having expansion capability. They were estimated to have the potential for increasing production by an 84,448,000 smolts weighting 4,853,306 pounds. 2 refs., 25 figs.

We also provide assistance to our Enterprise Screen Shop, in the Grande Ronde/Imnaha subbasins, if needed. All projects were designed and implemented under current National Marine Fisheries Service screening and passage criteria.

    On December 5, 1980, Congress passed the Pacific Northwest Electric Power Planning and Conservation Act (Public Law 96-501). The Act created the Northwest Power Planning Council (now the Northwest Power and Conservation Council). The Council was charged with the responsibility to prepare a Regional Conservation and Electric Power Plan and to develop a program to protect, mitigate, and enhance fish and wildlife including related spawning grounds and habitat on the Columbia River and its tributaries. The Council adopted its Fish and Wildlife Program on November 15, 1982. Section 800 of the Program addresses measures in the Yakima River Basin. The Yakima measures were intended to help mitigate hydroelectric impacts in the basin and provide off-site mitigation to compensate for fish losses caused by hydroelectric project development and operations throughout the Columbia River Basin. The Bonneville Power Administration (BPA) was designated as a major source of funding for such off-site mitigation measures and was requested to initiate discussions with the appropriate Federal project operators and the Council to determine the most expeditious means for funding and implementing the program. The primary measures proposed for rapid implementation in the Yakima River basin were the installation of fish passage and protective facilities. Sec. 109 of The Hoover Power Plant Act of 1984, authorized the Secretary of the Interior to design, construct, operate, and maintain fish passage facilities within the Yakima River Basin. Under Phase I of the program, improvements to existing fish passage facilities and installation of new fish ladders and fish screens at 16 of the largest existing diversion dams and canals were begun in 1984 and were completed in 1990. The Yakima Phase II fish passage program is an extension of the Phase I program. In 1988, the Yakama Nation (YN) submitted an application to amend Sections 803(b) and 1403(4.5) of the Northwest Power and Conservation Council

    The Idaho National Engineering Laboratory (INEL) is a Department of Energy (DOE) facility located in southeastern Idaho and occupies approximately 890 square miles on the northwestern portion of the eastern Snake River Plain. INEL has been devoted to nuclear energy research and related activities since its establishment in 1949. In the process of fulfilling this mission, wastes were generated, including radioactive and hazardous materials. Most materials were effectively stored or disposed of, however, some release of contaminants to the environment has occurred. For this reason, the INEL was listed by the US environmental Protection Agency on the National Priorities List (NPL), in November, 1989. This report describes the results of an ecological risk assessment performed for the Waste Area Groups 2 (WAG 2) at the INEL. It also summarizes the performance of screening level ecological risk assessments (SLERA).

    The methylmercury criterion adopted as a water-quality standard in the State of Idaho is a concentration in fish tissue rather than a concentration in water. A plan for monitoring mercury in fish tissue and water was developed to evaluate whether fish in the Boise River, Idaho, upstream and downstream of wastewater-treatment plant discharges, meet the methylmercury water-quality criterion. Monitoring also will be conducted at sites on the Snake River, upstream and downstream of the confluence with the Boise River, and in Brownlee Reservoir, which lies along the border between Idaho and Oregon. Descriptions of standard procedures for collecting and processing samples and quality assurance steps are included. This monitoring plan is intended to provide a framework for cooperative methylmercury sampling in the lower Boise River basin.

    Wild anadromous fish such as Pacific Chinook salmon (Oncorynchus tshawytscha) and steelhead (Oncorhyncus mykiss) were once abundant in Idaho, where they deposited their carcasses, rich in marine-derived nutrients (MDN), in the tributaries of the Columbia River. Anadromous fish are believed to have been a historically important nutrient source to the relatively nutrient-poor inland ecosystems of central Idaho, but no longer reach many inland watersheds due to presence of dams. This study investigates the multi-decadal cumulative effect of presence versus absence of anadromous fish nitrogen on net ecosystem exchange (NEE), or net carbon uptake, of riparian forests along historically salmon-bearing streams in the North Fork Boise River watershed, Idaho, in the context of a changing climate. The ecosystem process model BIOME-BGC is used to develop a representative forest ecosystem and predict the impact of decades of addition and continuing absence of MDN on NEE and net primary production (NPP). The study has 2 objectives: 1) to determine whether BIOME-BGC can reasonably simulate the riparian forests of central Idaho. A potentially confounding factor is the complex terrain of the region, particularly regarding soil water: water accumulation in valley bottoms and their riparian zones may lead to discrepancies in soil moisture and productivity of the riparian forest and of the simulations. The model is parameterized using local ecophysiology and site data and validated using field measurements of leaf area and soil moisture. Objective 2): to determine the effects on forest carbon balance and productivity of the presence or ongoing absence of anadromous-fish derived nitrogen. The forest simulation developed in objective 1 is run under two scenarios into the mid-20th century; one continuing without any supplemental nitrogen and one with nitrogen added in levels consistent with estimates of historical deposition by anadromous fish. Both scenarios incorporate warming due to

    As part of the U.S. Geological Survey's National Water Quality Assessment Program, fish assemblages, environmental variables, and associated mine densities were evaluated at 18 test and reference sites during the summer of 2000 in the Coeur d'Alene and St. Regis river basins in Idaho and Montana. Multimetric and multivariate analyses were used to examine patterns in fish assemblages and the associated environmental variables representing a gradient of mining intensity. The concentrations of cadmium (Cd), lead (Pb), and zinc (Zn) in water and streambed sediment found at test sites in watersheds where production mine densities were at least 0.2 mines/km2 (in a 500-m stream buffer) were significantly higher than the concentrations found at reference sites. Many of these metal concentrations exceeded Ambient Water Quality Criteria (AWQC) and the Canadian Probable Effect Level guidelines for streambed sediment. Regression analysis identified significant relationships between the production mine densities and the sum of Cd, Pb, and Zn concentrations in water and streambed sediment (r2 = 0.69 and 0.66, respectively; P < 0.01). Zinc was identified as the primary metal contaminant in both water and streambed sediment. Eighteen fish species in the families Salmonidae, Cottidae, Cyprinidae, Catostomidae, Centrarchidae, and Ictaluridae were collected. Principal components analysis of 11 fish metrics identified two distinct groups of sites corresponding to the reference and test sites, predominantly on the basis of the inverse relationship between percent cottids and percent salmonids (r = -0.64; P < 0.05). Streams located downstream from the areas of intensive hard-rock mining in the Coeur d'Alene River basin contained fewer native fish and lower abundances as a result of metal enrichment, not physical habitat degradation. Typically, salmonids were the predominant species at test sites where Zn concentrations exceeded the acute AWQC. Cottids were absent at these sites, which

    We evaluated the effectiveness of new fish screening facilities at the Richland and Wapato canals in south-central Washington State. The screen integrity tests at the Richland Screens indicated that 100% of fall chinook salmon fry (Oncorhynchus tshawytscha) released in front of the screens were prevented from entering the canal behind the screens. Our estimate is based on a 61% catch efficiency for control fish planted behind the screens. At the Wapato Canal, we estimated that between 3% and 4% of the test fish were either impinged on the screen surface and passed over the screens or passed through faulty screen seals. Our estimate is based over the screens or passed through faulty screen seals. Our estimate is based on a greater than 90% capture of control fish released in front of the screens. At the Wapato Screens, we estimated that 0.8% of steelhead smolts (Salmo gairdneri) and 1.4% of spring chinook salmon smolts released during low canal flow tests wee descaled. During full canal flow tests, 1.6% of the steelhead and 3.1% of the spring chinook salmon released were descaled. The fish return pipe at the Wapato Canal was tested: the estimate of descaled test fish wa not different from the estimate of descaled control fish. The time required for fish to exit from the Wapato Screen forebay varied with species and with canal flow. During low canal flows, 43.2% of steelhead and 61.6% of spring chinook salmon smolts released at the trash racks were captured in the fish return within 96 hr. 11 refs., 11 figs., 10 tabs.

    Fish in vivo screening methods to detect endocrine active substances, specifically interacting with the hypothalamic-pituitary-gonadal axis, have been developed by both the Organization for Economic Co-operation and Development (OECD) and United States Environmental Protection Agency (US-EPA). In application of these methods, i.e. regulatory testing, this paper provides a proposal on the setting of test concentrations using all available acute and chronic data and also discusses the importance of avoiding the confounding effects of systemic toxicity on endocrine endpoints. This guidance is aimed at reducing the number of false positives and subsequently the number of inappropriate definitive vertebrate studies potentially triggered by effects consequent to systemic, rather than endocrine, toxicity. At the same time it provides a pragmatic approach that maximizes the probability of detecting an effect, if it exists, thus limiting the potential for false negative outcomes.

    The Yankee Fork is a large tributary of the Salmon River located in central Idaho, USA, with an extensive history of placer and dredge-mining activities. Concentrations of selenium (Se) and mercury (Hg) in various aquatic trophic levels were measured in the Yankee Fork during 2001 and 2002. Various measurements of fish health were also performed. Sites included four on the mainstem of the Yankee Fork and two off-channel sites in partially reclaimed dredge pools used as rearing habitat for cultured salmonid eggs and fry. Hg concentrations in whole mountain whitefish and shorthead sculpin ranged from 0.28 to 0.56 μg/g dry weight (dw), concentrations that are generally less than those reported to have significant impacts on fish. Biofilm and invertebrates ranged from 0.05 to 0.43 μg Hg/g dw. Se concentrations measured in biota samples from the Yankee Fork were greater than many representative samples collected in the Snake and Columbia watersheds and often exceeded literature-based toxic thresholds. Biofilm and invertebrates ranged from 0.58 to 4.66 μg Se/g dw. Whole fish ranged from 3.92 to 7.10 μg Se/g dw, and gonads ranged from 6.91 to 31.84 μg Se/g dw. Whole-body Se concentrations exceeded reported toxicological thresholds at three of four sites and concentrations in liver samples were mostly greater than concentrations shown to have negative impacts on fish health. Histological examinations performed during this study noted liver abnormalities, especially in shorthead sculpin, a bottom-dwelling species.

    Mercury (Hg) is a globally distributed pollutant that poses considerable risks to human and wildlife health. Over the past 150 years since the advent of the industrial revolution, approximately 80 percent of global emissions have come from anthropogenic sources, largely fossil fuel combustion. As a result, atmospheric deposition of Hg has increased by up to 4-fold above pre-industrial times. Because of their isolation, remote high-elevation lakes represent unique environments for evaluating the bioaccumulation of atmospherically deposited Hg through freshwater food webs, as well as for evaluating the relative importance of Hg loading versus landscape influences on Hg bioaccumulation. The increase in Hg deposition to these systems over the past century, coupled with their limited exposure to direct anthropogenic disturbance make them useful indicators for estimating how changes in Hg emissions may propagate to changes in Hg bioaccumulation and ecological risk. In this study, we evaluated Hg concentrations in fishes of high-elevation, sub-alpine lakes in the Wallowa-Whitman National Forest in northeastern Oregon and western Idaho. Our goals were to (1) assess the magnitude of Hg contamination in small-catchment lakes to evaluate the risk of atmospheric Hg to human and wildlife health, (2) quantify the spatial variability in fish Hg concentrations, and (3) determine the ecological, limnological, and landscape factors that are best correlated with fish total mercury (THg) concentrations in these systems. Across the 28 study lakes, mean THg concentrations of resident salmonid fishes varied as much as 18-fold among lakes. Importantly, our top statistical model explained 87 percent of the variability in fish THg concentrations among lakes with four key landscape and limnological variables— catchment conifer density (basal area of conifers within a lake’s catchment), lake surface area, aqueous dissolved sulfate, and dissolved organic carbon.

    Diversions from streams are often screened to prevent the loss of or injury to fish. Hydraulic criteria meant to protect fish that encounter screens have been developed, but primarily for screens that are vertical to the water flow rather than horizontal. For this reason, we measured selected hydraulic variables and released wild rainbow trout Oncorhynchus mykiss over two types of horizontal flat-plate fish screens in the field. Our goal was to assess the efficacy of these screens under a variety of conditions in the field and provide information that could be used to develop criteria for safe fish passage. We evaluated three different invertedweir screens over a range of stream (0.24-1.77 m3/s) and diversion flows (0.10-0.31 m3/s). Approach velocities (AVs) ranged from 3 to 8 cm/s and sweeping velocities (SVs) from 69 to 143 cm/s. We also evaluated a simple backwatered screen over stream flows of 0.23-0.79 m3/s and diversion flows of 0.08-0.32 m3/s. The mean SVs for this screen ranged from 15 to 66 cm/s and the mean AVs from 1 to 5 cm/s. The survival rates of fish held for 24 h after passage over these screens exceeded 98%. Overall, the number of fish-screen contacts was low and the injuries related to passage were infrequent and consisted primarily of minor fin injuries. Our results indicate that screens of this type have great potential as safe and effective fish screens for small diversions. Care must be taken, however, to avoid operating conditions that produce shallow or no water over the screen surface, situations of high AVs and low SVs at backwatered screens, and situations producing a localized high AV with spiraling flow. ??

    The lower Kootenai River, Idaho, was sampled during the summers of 2012 and 2013 to evaluate its fish assemblage structure at seven sites within main- and side-channel habitats where large-scale habitat rehabilitation was undertaken. Understanding the current patterns of fish assemblage structure and their relationships with habitat is important for evaluating the effects of past and future rehabilitation projects on the river. Species-specific habitat associations were modeled, and the variables that best explained the occurrence and relative abundance of fish were identified in order to guide future habitat rehabilitation so that it benefits native species. The results indicated that the side-channel habitats supported higher species richness than the main-channel habitats and that nonnative fishes were closely associated with newly rehabilitated habitats. This research provides valuable insight on the current fish assemblages in the Kootenai River and the assemblage-level responses that may occur as a result of future rehabilitation activities.

    Screens are commonly installed at water diversion sites to reduce entrainment of fish. Recently, the Farmers Irrigation District in Hood River, Oregon, developed a new flat-plate screen design that offers passive operation and may result in reduced operation and installation costs to irrigators. To evaluate the performance (its biological effect on fish) of this type of screen, two size classes of juvenile coho salmon (Oncorhynchus kistuch) were released over a small version of this screen in the field-the Herman Creek screen. The performance of the screen was evaluated over a range of inflow [0.02 to 0.42 m3/s (cubic meters per second)] and diversion flows (0.02 to 0.34 m3/s) at different weir wall heights. The mean approach velocities for the screen ranged from 0 to 5 cm/s (centimeters per second) and mean sweeping velocities ranged from 36 to 178 cm/s. Water depths over the screen surface ranged from 1 to 25 centimeters and were directly related to weir wall height and inflow. Passage of juvenile coho salmon over the screen under a variety of hydraulic conditions did not severely injure them or cause delayed mortality. For all fish, the mean percentage of body surface area that was injured after passage over the screen ranged from about 0.4 to 3.0%. This occurred even though many fish contacted the screen surface during passage. No fish were observed becoming impinged on the screen surface (greater than 1 second contact with the screen). When operated within its design criteria (diversion flows of about 0.28 m3/s), the screen provided safe and effective downstream passage of juvenile salmonids under a variety of hydraulic conditions. However, we do not recommend operating the screen at inflows less than 0.14 m3/s (5 ft3/s) because water depth can get quite shallow and the screen can completely dewater, particularly at very low flows.

    The Pacific Northwest Laboratory (PNL) measured the velocity conditions at three fish screening facilities in the Yakima River Basin: Wapato, Chandler, and Easton Screens. The measurement objectives were different at the three screens. At Wapato, approach and sweep velocities were measured to evaluate the effect of rearing pens in the screen forebay. A complete survey was performed at the Chandler Screens. At Easton, velocity was measured behind the screens to provide information for the installation of porosity boards to balance flow through the screens. Salmon-rearing pens used at the Wapato Canal had a minimal effect on the magnitude of approach and sweep velocities at the face of the drum screens, although the pens caused increased turbulence and variability in water velocities. The net pens did not appear to affect flows through the three fish bypasses. 8 refs., 17 figs., 5 tabs.

Pacific Northwest National Laboratory collected data to determine whether velocities in front of the screens and in the bypasses met National Marine Fisheries Service criteria to promote safe and timely fish passage and whether bypass outfall conditions allowed fish to safely return to the river. In addition, Pacific Northwest National Laboratory conducted underwater video surveys to evaluate the environmental and operational conditions of the screen sites with respect to fish passage. Based on evaluations in 2002, PNNL concluded that: (1) In general, water velocity conditions at the screen sites met fish passage criteria set by the National Marine Fisheries Service. (2) Conditions at most facilities would be expected to provide for safe juvenile fish passage.

    The Pacific Northwest Laboratory (PNL) evaluated the effectiveness of new fish screening facilities in the Westside Ditch and Town Canal, near Ellensburg, in south-central Washington State. At the Town Canal, we estimated that 0.3% of steelhead Oncorhynchus mykiss smolts released during tests were significantly descaled. The time required for 50% of the fish in the two steelhead test groups to exit from the Town Screens forebay ranged from 12 h to >85 h. Integrity tests at the Town Screens indicated that none of the rainbow trout fry released in front of the rotary drum screens passed through the screens, although 8.5% of the native zero-age chinook salmon fry diverted from the river into the screening facility were lost through the screens. At the Westside Screens, 16.8% of native zero-age chinook salmon fry passed through the screens. Most of the chinook salmon lost through the screens were small, <36 mm long. The methods used in 1990 were first used at the Sunnyside Screens in 1985. These methods were used again in subsequent years in tests at the Richland, Toppenish/Satus, Wapato, and Toppenish Creek screens. The methods used from 1985 through 1989 have been reviewed by the Washington State Department of Fisheries, US Fish and Wildlife Service, National Marine Fisheries Service, Northwest Power Planning Council, and Yakima Indian Nation. 14 refs., 12 figs., 7 tabs.

    The need to provide passage and protective screens at irrigation diversions has always been a necessary part of the Columbia River Basin Fish and Wildlife Program (NPPC 1984, 1987, 1994). From 1985 through 1990, fish protection facilities in large irrigation diversions throughout the Columbia Basin, especially in the Yakima Basin, were updated. After 1990, fish protection efforts turned to installation of new facilities on unscreened diversions and to repair and upgrade of older facilities. The screening program also includes funds to monitor and evaluate the facilities. The screen evaluations indicate they are an effective means for protecting juvenile fish larger than 40 mm in length. As state and federal agencies change screening criteria to protect smaller fish (e.g., bull trout fry), the physical barrier may not always be effective. Screen mesh small enough to protect fish may be vulnerable to frequent plugging. Gap tolerances on side and bottom seals may be difficult to install and maintain. Physical barrier screens can be enhanced with behavioral barriers that cause fish to avoid a hazard. Behavioral barriers may consist of sound generator, strobe lights, bubble curtains, or electrical barriers. State of Oregon House Bill 3112 states that "Standards and criteria shall address the overall level of protection necessary at a given water diversion and shall not favor one technology or technique over another." Additionally, it goes on to say, "Screening device means a fish screen or behavior barrier." Other Northwest states, in particular Washington, have taken a comprehensive program to install barriers at all unscreened diversions by 1999. Protecting all fish at all water withdrawals will probably require both physical and behavioral barriers. The purpose of this study is to evaluate the effectiveness of using an underwater sound-generator as a behavioral barrier for possible use at fish diversion facilities.

    Effectivness was evaluated of the Dryden Fish Screening Facility in the Wenatchee Reclamation District Canal near Dryden in north central Washington State. In situ tests were conducted by releasing groups of hatchery reared salmonids of different ages and sizes. Spring chinook salmon smolts (110-165 mm) were not injured or descaled in passing through the canal forebay. Smolts were not delayed as they migrated in the canal. Most fish released at the canal headworks exited the screening facility in <4 h, with >99% of the test fish captured in the fish bypass in <24 h. Steelhead subyearlings 65-125 mm were not injured or descaled in traveling through the bypass flume and fish return pipe. Average time for steelhead subyearlings to travel through thebypass structure was 70 seconds. Small rainbow trout fry 23-27mm could pass through the 0.125-in. profile bar screen openings and were entrained in the irrigation canal; about 38% was lost to the canal within 48 h of release. Some fry stayed in the forebay and did not migrate during the tests. Wild chinook fry 36-42mm were also entrained. Estimated 34% of emergent wild chinook salmon fry passed through the profile bar screens and were entrained in the canal. Approach velocity at the Dryden screens was {ge}0.4 ft/s; low velocities through the first two screen panels indicated that vertical louvers installed behind each screen panel to balance flow were not totally effective.

    The Bonneville Power Administration, the United States Bureau of Reclamation, and the Washington State Department of Ecology are funding the construction and evaluation of fish passage and protection facilities at irrigation and hydroelectric diversions in the Yakima River Basin, Washington State. The programs provide offsite enhancement to compensate for fish and wildlife losses caused by hydroelectric development throughout the Columbia River Basin, and they address natural propagation of salmon to help mitigate the impact of irrigation in the Yakima River Basin. The Westside Ditch and Wapato Screens are two of the juvenile screening facilities. This report evaluates the effectiveness of the screens facilities for intercepting and returning juvenile salmonids unharmed to the Yakima River from which they were diverted. We evaluated the effectiveness of new fish screening facilities in the Westside Ditch and Wapato Canal in south-central Washington State. The screen integrity tests indicated that test fish released in front of the screens could enter the canal behind the screens. The study emphasized salmonids. Test fish were steelhead Oncorhynchus mykiss smolts, spring chinook salmon O. tshawytscha smolts, and rainbow trout O. mykiss fry. Evaluations were conducted during typical spring flows in the diversion. 13 refs., 10 figs., 6 tabs.

    Many studies estimate that chromosomal mosaicism within the cleavage-stage human embryo is high. However, comparison of two unique methods of aneuploidy screening of blastomeres within the same embryo has not been conducted and may indicate whether mosaicism has been overestimated due to technical inconsistency rather than the biological phenomena. The present study investigates the prevalence of chromosomal abnormality and mosaicism found with two different single cell aneuploidy screening techniques. Thirteen arrested cleavage-stage embryos were studied. Each was biopsied into individual cells (n = 160). The cells from each embryo were randomized into two groups. Those destined for FISH-based aneuploidy screening (n = 75) were fixed, one cell per slide. Cells for SNP microarray-based aneuploidy screening (n = 85) were put into individual tubes. Microarray was significantly more reliable (96%) than FISH (83%) for providing an interpretable result (P = 0.004). Markedly different results were obtained when comparing microarray and FISH results from individual embryos. Mosaicism was significantly less commonly observed by microarray (31%) than by FISH (100%) (P = 0.0005). Although FISH evaluated fewer chromosomes per cell and fewer cells per embryo, FISH still displayed significantly more unique genetic diagnoses per embryo (3.2 ± 0.2) than microarray (1.3 ± 0.2) (P < 0.0001). This is the first prospective, randomized, blinded and paired comparison between microarray and FISH-based aneuploidy screening. SNP microarray-based 24 chromosome aneuploidy screening provides more complete and consistent results than FISH. These results also suggest that FISH technology may overestimate the contribution of mitotic error to the origin of aneuploidy at the cleavage stage of human embryogenesis. PMID:20484246

    Pacific Northwest National Laboratory (PNNL) evaluated 20 Phase II screen sites in the Yakima River Basin as part of a multi-year study for the Bonneville Power Administration (BPA) on the effectiveness of fish screening devices. The sites were examined to determine if they were being effectively operated and maintained to provide fish a safe, efficient return to the Yakima River. Data were collected to determine if velocities in front of the screens and in the bypass met current National Marine Fisheries Service (NMFS) criteria to promote safe and timely fish bypass and whether bypass outfall conditions allowed fish to safely return to the river. In general, water velocity conditions at the screen sites met fish passage criteria set forth by the NMFS. Although velocities often fluctuated from one sampling location to the next, average sweep velocities typically exceeded approach velocities and increased toward the bypass. Mean approach velocities were below the NMFS criteria of < 0.4 feet per second (fps) at most sites (Table 1). Based on our observations in 1999, we believe that most facilities were efficiently protecting juvenile fish from entrainment, impingement, or migration delay. Most screens were properly sealed to prevent fish entrainment and injury, although potential problems were identified at several screen sites. Six sites (one fewer than the seven sites identified in 1998) had loose or damaged seals that might have allowed fish to be entrained (Table 1). Other sites still had spaces larger than 3/32 in. where small fish could possibly pass into the irrigation canal.

    The Coeur d`Alene Basin, Idaho is the traditional homeland of the Coeur d`Alene Tribe. The sediments and surface waters of the Coeur d`Alene River (CDR) contain elevated concentrations of metals as a result of waste generated during mining activities initiated in the 1800s. As part of a Natural Resource Damage Assessment (NRDA) being conducted on the Coeur d`Alene Basin, the authors studied the biological pathway of metals in the CDR. For metal residue analyses, they collected biofilm, benthic macroinvertebrates and sediments from ten sites on the CDR and one site on the Spokane River (downstream from the CDR). Reference samples were also collected from one site on the St. Joe River. Yellow perch were collected from three sites on the CDR and from one site on the St. Joe River. Biofilm is the combination of abiotic and biotic material on rock surfaces along the river and represents the diet of benthic macroinvertebrates. The concentrations of metals in biofilm ({micro}g/g dry wt., N = 4) were As: 7.99, and 149; Cd: 2, 179, and 21; Pb: 18, 2,015, and 3,460; Hg: < 0.051, 5, and 2; and Zn: 67, 11,578, and 4,543 respectively from the St. Joe River, the South Fork of the CDR and the CDR near Harrison about 30 miles downstream from the South Fork. Some metals moved through the food-chain as the mean concentrations of metals in whole fish ({micro}/g dry wt., N = 4) were Cd: < 0.05 and 1.14; Pb: > 0.34 and 55; and Zn: 87 and 184, respectively in samples from the St. Joe River and the CDR near Harrison. Tissue metals were measured in macroinvertebrates and the authors determined the influence of size and trophic level on the accumulation of metals.

We evaluated the effectiveness of new screening facilities at the Toppenish Creek, Wapato, and Sunnyside canals in southcentral Washington State. Screen integrity tests indicated that fish released in front of the screens were prevented from entering the canal behind the screens. We conducted descaling tests at the Toppenish Creek Screens. We measured the time required for fish to move through the screen facilities. Methods used in 1988 were the same as those used at Sunnyside in 1985 and in subsequent years at Richland.

    Fish-tissue and bed-sediment samples were collected to determine the occurrence and distribution of organochlorine compounds and trace elements in the lower Snake River Basin. Whole-body composite samples of suckers and carp from seven sites were analyzed for organochlorine compounds; liver samples were analyzed for trace elements. Fillets from selected sportfish were analyzed for organochlorine compounds and trace elements. Bed-sediment samples from three sites were analyzed for organochlorine compounds and trace elements. Twelve different organochlorine compounds were detected in 14 fish-tissue samples. All fish-tissue samples contained DDT or its metabolites. Concentrations of total DDT ranged from 11 micrograms per kilogram wet weight in fillets of yellow perch from C.J. Strike Reservoir to 3,633 micrograms per kilogram wet weight in a whole-body sample of carp from Brownlee Reservoir at Burnt River. Total DDT concentrations in whole-body samples of sucker and carp from the Snake River at C.J. Strike Reservoir, Snake River at Swan Falls, Snake River at Nyssa, and Brownlee Reservoir at Burnt River exceeded criteria established for the protection of fish-eating wildlife. Total PCB concentrations in a whole-body sample of carp from Brownlee Reservoir at Burnt River also exceeded fish-eating wildlife criteria. Concentrations of organochlorine compounds in whole-body samples, in general, were larger than concentrations in sportfish fillets. However, concentrations of dieldrin and total DDT in fillets of channel catfish from the Snake River at Nyssa and Brownlee Reservoir at Burnt River, and concentrations of total DDT in fillets of smallmouth bass and white crappie from Brownlee Reservoir at Burnt River exceeded a cancer risk screening value of 10-6 established by the U.S. Environmental Protection Agency. Concentrations of organochlorine compounds in bed sediment were smaller than concentrations in fish tissue. Concentrations of p,p'DDE, the only compound detected

    The authors analyzed streambed sediment and fish in the Central Columbia Plateau in eastern Washington and Idaho for organochlorine pesticides and polychlorinated biphenyls ({Sigma}PCB). The objective was to assess the effects of land use on the occurrence and distribution of these compounds; land uses in the study area included forest, dryland and irrigated farming, and urban. The authors detected 16 organochlorine compounds in streambed sediment and fish tissue; fish usually had more compounds and a greater frequency of detection. The most frequently detected compound was {Sigma}DDT (sum of six isomers), which was found in 52% of bed sediment samples and 94% of whole fish composite samples. The other commonly detected compounds were dimethyl tetrachloroterephthalate (DCPA), dieldrin, hexachlorobenzene, and {Sigma}chlordane. Forest was the only land use with no detections of organochlorine compounds in either fish or bed sediment. Hexachlorobenzene was the only organochlorine pesticide detected at concentrations that differed significantly among land uses: concentrations were higher in the dryland farming areas than in the irrigated farming or urban areas. In agricultural areas irrigated by surface water, {Sigma}DDT concentrations in both streambed sediment and fish tissue were related to the percentage of land irrigated by water delivered via furrows (gravity irrigation), although {Sigma}DDT was not detectable in bed sediments until gravity irrigation exceeded 30%. Because of the relation between gravity irrigation and soil erosion, the study supports the importance of controlling soil erosion in order to reduce the overall loading of organochlorine compounds to surface waters.

    Pacific Northwest National Laboratory (PNNL) evaluated 21 Phase II screen sites in the Yakima River Basin as part of a multi-year study for the Bonneville Power Administration (BPA) on the effectiveness of fish screening devices. The sites were examined in 1997, 1998, 1999, and 2000 to determine if they were being effectively operated and maintained to provide fish a safe, efficient return to the Yakima River. Data were collected to determine if velocities in front of the screens and in the bypass met current National Marine Fisheries Service (NMFS) criteria to promote safe and timely fish bypass and whether bypass outfall conditions allowed fish to safely return to the river. Based on the results of our studies in 2000, we conclude that: in general, water velocity conditions at the screen sites met fish passage criteria set forth by the NMFS; most facilities were efficiently protecting juvenile fish from entrainment, impingement, or migration delay; automated cleaning brushes generally functioned properly; chains and other moving parts were well greased and inoperative; and removal of sediment build-up and accumulated leafy and woody debris are areas that continue to improve.

    TVA analyzes tissues of Tennessee Valley area fish as part of intensive evaluations and as pat of screening level evaluations. Intensive studies are conducted in reservoirs where contamination problems are known or suspected and include analysis of individual fillets from important fish species from several areas in the reservoir. This information is used by State public health officials to determine whether fish consumption advisories are necessary to protect human health. Screening studies are based on analysis of composite rather than individual samples and are intended to provide trend information and to identify areas where problems may exist indicating need for an intensive evaluation. All studies are coordinated with State agencies because they ultimately must make management decisions regarding public health. TVA has two fish tissue screening programs. One examines fish on an annual basis at inflow points from eight of the major tributaries into the Tennessee River reservoir system. The other examines fish from within the reservoirs on a rotating basis with the goal of sampling each reservoir at least once every three years. 7 refs., 1 fig., 8 tabs.

    Standard laboratory rat neurotoxicity protocols were used to study the consequences resulting from the consumption of walleye (Stizostedion vitreum), whitefish (Coregonus clupeaformis), and lake trout (Salvelinus namaycush) from Lake Superior (LS) and the consumption of carp (Cyprinus carpio) from Little Lake Butte des Morte (LLBM) near Oshkosh, Wisconsin, USA. Two 90-d subchronic studies are described, including a 45-d exposure to fish diets using male Sprague-Dawley hooded rats, and a 90-d exposure to fish diets using female rats of the same species. Behavioral alterations were tested using a battery of behavioral tests. In addition, pharmacologic challenges using apomorphine and D-amphetamine were administered to the rats to reveal latent neurotoxic effects. Cumulative fish consumption data were recorded daily, weight gain recorded weekly, and behavior data collected prior to exposure, and on days 7, 14, 55 {+-} 2, 85 {+-} 2. Motor activity data were collected on days 30 {+-} 2, 60 {+-} 2, and 90 {+-} 2 of the feeding protocols. Brain tissue from rodents fed these fish were subsequently analyzed for either mercury (Hg) or polychlorinated biphenyls (PCB). Mercury concentrations were increased in the brains of the walleye-fed rats, and PCB concentrations ranged from 0.5 nl/L to 10 nl/L in the brains of rats fed carp from LLBM, a Lake Michigan tributary. Adult male rats fed LLBM carp for 45 d exhibited the greatest behavior responses to the dopaminergic agonist apomorphine on the accelerating rotarod, although these differences were not significant. The 90-d exposure of LS walleye or Hg-spiked LS walleye resulted in behavior alterations on tactile startle response and second footsplay. D-Amphetamine challenge caused changes in tactile startle response, second footsplay, and accelerating rotarod performance after consuming walleye diets. Rats fed LLBM carp had altered behavioral responses to apomorphine on the accelerating rotarod.

    The Pacific Northwest National Laboratory evaluated 19 Phase II screen sites in the Yakima River Basin at least three times each between April 30 and August 22, 1997. The sites were examined to determine if they were being effectively operated and maintained to provide fish a safe, efficient return to the river. Data were collected to determine if velocities in front of the screens and in the bypass met current NMFS criteria and promoted timely fish bypass, if fish were protected from injury due to impingement, entrainment, and predation, and whether bypass outfall conditions allowed fish to safely return to the river. A bi-directional flow meter and underwater video system were essential in completing the investigation. In general, water velocity conditions at the screen sites were acceptable by NMFS standards. High approach velocities and slow bypass flow were the most common problems noted. Although velocities often fluctuated from one sampling location to the next, average sweep and approach velocities were very good. In general, fish should not be impinged or experience delays in returning to the river under normal operating conditions. Most screens were properly sealed to prevent fish entrainment and injury, although potential problems were identified at several screen sites. Three sites had gap openings from the forebay to the aftbay, allowing fish to be entrained. Other sites had spaces larger than 3/32 inch where small fish could become trapped. Some drum screens had flat spots but these were not been confirmed as underwater gaps, primarily because of siltation. On rare occasions, seals were intact, but cracked or turned under. Submergence levels at the drum screen sites exceeded 85% for one third of our evaluations. Eight of 12 drum screen sites experienced high water levels during at least one evaluation. Only one operating site's submergence was measured at less than 65% submergence. Two flat plate screen sites were completely overtopped with water

    The Bonneville Power Administration is proposing to fund a fish passage enhancement project on Twelvemile Creek in Lemhi County, Idaho with the Lemhi Soil and Water Conservation District. The goal of this project is to enhance fish passage in Twelvemile Creek by eliminating barriers and increasing flows. The project goals will be accomplished by eliminating two diversions and two pumps from Twelvemile Creek by consolidating the flow into one diversion, eliminating ditch loss with pipe, and switching one irrigator from flood to sprinkler irrigation. This project will also attach the irrigators to a fish screen that will be installed by the Idaho Department of Fish and Game.

    The Pacific Northwest National Laboratory (PNNL) performed tests to determine whether a significant difference in fish passage existed between a 6-ft screening facility built perpendicularly to canal flow and an identical screening facility with the screen mounted at a 45-degree angle to the approach channel. A modular drum screen built by the Washington Department of Fish and Wildlife was installed at PNNL`s Aquatic Ecology research laboratory in Richland, Washington. Fall chinook salmon fry were introduced into the test system, and their movements were monitored. A total of 14 tests (400 fish per test) that lasted 20 hours were completed during April and May, 1996. There was no significant difference in fish passage rate through the two approach configurations. Attraction flow to the bypass across the face of the screen was more evident for the angled approach, although this did not appear to play a significant role in attracting fish to the bypass. Approach velocities at the face of the screen did not exceed the 0.4 fps criteria for either approach configuration and posed not threat to fish. No fish passed over, around, or through the drum screen during any test.

    Preventing the introduction of potentially invasive species is becoming more important as this worldwide problem continues to grow. The ability to predict the identity or range of potential invaders could influence regulatory decisions and help to optimally allocate resources to deal with ongoing invasions. One screening tool presented here, using species life history and environmental tolerances to identify potential invaders similar to past invaders, can be used to predict potential invading species. Another screening tool, genetic algorithms, can be used to predict the potential range of an invading species. Use and further development of tools such as these, that are quantitative and relatively transparent, would give managers and other decision makers more information for making better-informed decisions.

    Screens are installed at water diversion sites to reduce entrainment of fish. Recently, the Farmers Irrigation District (Oregon) developed a unique flat-plate screen (the “Farmers Screen”) that operates passively and may offer reduced installation and operating costs. To evaluate the effectiveness of this screen on fish, we conducted two separate field experiments. First, juvenile coho salmon Oncorhynchus kisutch were released over a working version of this screen under a range of inflows (0.02–0.42 m3/s) and diversion flows (0.02–0.34 m3/s) at different water depths. Mean approach velocities ranged from 0 to 5 cm/s and sweeping velocities ranged from 36 to 178 cm/s. Water depths over the screen surface ranged from 1 to 25 cm and were directly related to inflow. Passage of fish over the screen under these conditions did not severely injure them or cause delayed mortality, and no fish were observed becoming impinged on the screen surface. Second, juvenile coho salmon and steelhead O. mykiss were released at the upstream end of a 34-m flume and allowed to volitionally move downstream and pass over a 3.5-m section of the Farmers Screen to determine whether fish would refuse to pass over the screen after encountering its leading edge. For coho salmon, 75–95% of the fish passed over the screen within 5 min and 82–98% passed within 20 min, depending on hydraulic conditions. For steelhead, 47–90% of the fish passed over the screen within 5 min and 79–95% passed within 20 min. Our results indicate that when operated within its design criteria, the Farmers Screen provides safe and efficient downstream passage of juvenile salmonids under a variety of hydraulic conditions.

Our objective was to assess the effects of land use on the occurrence and distribution of these compounds; land uses in the study area included forest, dryland and irrigated farming, and urban. We detected 16 organochlorine compounds in streambed sediment and fish tissue; fish usually had more compounds and a greater frequency of detection. The most frequently detected compound was ΣDDT (sum of six isomers), which was found in 52% of bed sediment samples and 94% of whole fish composite samples. The other commonly detected compounds were dimethyl tetrachloroterephthalate (DCPA), dieldrin, hexachlorobenzene, and Σchlordane (sum of cis- and trans-chlordane, cis- and trans-nonachlor oxychlordane, heptachlor, and heptachlor epoxide). Forest was the only land use with no detections of organochlorine compounds in either fish or bed sediment. Hexachlorobenzene was the only organochlorine pesticide detected at concentrations that differed significantly among land uses: concentrations were higher in the dryland farming areas than in the irrigated farming or urban areas.

    In 2006, Pacific Northwest National Laboratory (PNNL) researchers evaluated 27 Phase II fish screen sites in the Yakima and Touchet river basins. Pacific Northwest National Laboratory performs these evaluations for Bonneville Power Administration (BPA) to determine whether the fish screening devices meet those National Marine Fisheries (NMFS) criteria for juvenile fish screen design, that promote safe and timely passage of juvenile salmonids. The NMFS criteria against which the sites were evaluated are as follows: (1) a uniform flow distribution over the screen surface to minimize approach velocity; (2) approach velocities less than or equal to 0.4 ft/s protects the smallest salmonids from impingement; (3) sweep velocities that are greater than approach velocities to minimize delay of out-migrating juveniles and minimize sediment deposition near the screens; (4) a bypass flow greater than or equal to the maximum flow velocity vector resultant upstream of the screens to also minimize delay of out-migrating salmonids; (5) a gradual and efficient acceleration of flow from the upstream end of the site into the bypass entrance to minimize delay of out-migrating salmonids; and (6) screen submergence between 65% and 85% for drum screen sites. In addition, the silt and debris accumulation next to the screens should be kept to a minimum to prevent excessive wear on screens, seals and cleaning mechanisms. Evaluations consist of measuring velocities in front of the screens, using an underwater camera to assess the condition and environment in front of the screens, and noting the general condition and operation of the sites. Results of the evaluations in 2006 include the following: (1) Most approach velocities met the NMFS criterion of less than or equal to 0.4 ft/s. Of the sites evaluated, 31% exceeded the criterion at least once. Thirty-three percent of flat-plate screens had problems compared to 25% of drum screens. (2) Woody debris and gravel deposited during high river

    Sixty fish screen facilities were constructed in the Yakima River basin between 1985 and 2006 as part of the Northwest Power and Conservation Council plan to mitigate the effects of federal hydroelectric projects on fish and wildlife populations. This report summarizes evaluations of some of those and other fish screen facilities conducted by Pacific Northwest National Laboratory (PNNL) from 1985 through 2006. The objective of these studies was to determine if the newly designed and constructed fish screens were effective at providing juvenile salmonids safe passage past irrigation diversions. To answer that question, PNNL conducted release-and-catch studies at eight Phase I sites in the Yakima River basin. Increasing concerns about the impacts of hatchery fish releases on the wild fish population, as well as the cost and time necessary to perform these kinds of biological studies at more than 60 planned Phase II sites, required development of techniques to evaluate the effectiveness of the sites without releasing fish. The new techniques involved collecting information on screen design, operation, and effectiveness at guiding fish safely through the fish screen facility. Performance measures including water velocities and passage conditions provide a good alternative to biological studies at significantly lower cost and time. Physical techniques were used at all 10 Phase I and 28 Phase II sites evaluated by PNNL over the following 19 years. Results of these studies indicate the Phase I and II fish screen facilities are designed and capable of providing safe passage for juvenile salmonids so long as construction, maintenance, and operations meet the criteria used in the design of each site and the National Marine Fisheries Service criteria for juvenile fish screen design.

    We evaluated the effectiveness of new screening facilities at the Toppenish Creek, Wapato, and Sunnyside canals in southcentral Washington State. Screen integrity tests indicated that fish released in front of the screens were prevented from entering the canal behind the screens. Screen efficiency estimates are 99% ({+-}0.6%) for Toppenish Creek, 99% ({+-}0.3%) for Wapato, and 98% ({+-}0.5%) for Sunnyside. During 1987 at the Wapato Canal, we estimated screen efficiency was 97% ({+-}l%). We conducted descaling tests at the Toppenish Creek Screens. We estimated that 0.2% of steelhead Qncorhynchus mykiss smelts released during tests were descaled. None of the fish released through the fish return pipe were descaled. We measured the time required for fish to move through the screen facilities. The time required for 50% of the test fish to exit the Toppenish Creek Screen forebay was 4 to 9 h for rainbow trout fry and up to 39 h for steelhead smelts. The time for 50% of the test fish to exit the Wapato and Sunnyside screen forebays was less than 8 h. As with past studies, exit times varied with canal flow and species. After 39 h at Toppenish Creek, half the steelhead smelts were still in the forebay when canal flows were 20 cfs. At Sunnyside, half the chinook salmon fry exited the forebay in 1 h or less. Methods used in 1988 were the same as those used at Sunnyside in 1985 and in subsequent years at Richland, Toppenish/Satus, and Wapato. The methods and previous results have been reviewed by the Washington State Department of Fisheries, U.S. Fish and Wildlife Service, National Marine Fisheries Service, Northwest Power Planning Council, and Yakima Indian Nation.

    Hollow fibre cell fishing with high performance liquid chromatography (HFCF-HPLC) is a newly developed method used to screen and fish bioactive compounds in traditional Chinese medicines (TCMs). In the study, colorectal cancer cell HCT116 was first seeded in a hollow fibre and used for screening and fishing active compounds from TCMs. The surface properties of the hollow fibre seeded with HCT116 cells, the non-specific binding between active centres in the fibre and the target compounds, the cell survival rate under different conditions before and after screening, the repeatability and recovery of HFCF-HPLC were investigated in detail. The cell fishing factor of active compound was defined in HFCF-HPLC. We employed HFCF-HPLC to screen and fish anthraquinones active compounds group from extracts of Polygonum cuspidatum, Cecropia obtusifolia L. and Polygoni multiflori radix praeparata. Some of the anthraquinones structures screened from TCMs were identified by comparing to the retention time of the reference substances confirmed by mass spectrometry. The ability of permeable membrane of anthraquinones screened by HFCF-HPLC was further described. Indomethacin was used as the positive control substance. Results demonstrated that HFCF-HPLC is an effective, stable and reliable method to screen and analyse bioactive compounds. Other bioactive compounds from TCMs could also be screened. PMID:24275485

    Mineral surveys conducted in the Idaho Wilderness identified 28 areas with probable or substantiated mineral-resource potential, and 5 mines with demonstrated or inferred resources. Metals including gold, silver, copper, lead, zinc, and tungsten, have been extracted from deposits inside the wilderness. Current studies indicate additional areas of probable mineral-resource potential for gold, tungsten, mercury, rare-earth elements, and base metals related to intrusive rocks that follow structures formed by cauldron subsidence. These on-going studies also indicate that there is probable and substantiated resource potential for cobalt with copper, silver, and gold in the Precambrian rocks in the northeastern part of the wilderness in a geologic environment similar to that of the Blackbird mine that lies outside the area. The nature of the geologic terrane precludes the potential for organic fuels.

    Mercury (Hg) analyses were conducted on samples of sport fish and water collected from selected sampling sites in Brownlee Reservoir and the Boise and Snake Rivers to meet National Pollution Discharge and Elimination System (NPDES) permit requirements for the City of Boise, Idaho, between 2013 and 2015. City of Boise personnel collected water samples from six sites between October and November 2013 and 2015, with one site sampled in 2014. Total Hg concentrations in unfiltered water samples ranged from 0.48 to 8.8 nanograms per liter (ng/L), with the highest value in Brownlee Reservoir in 2013. All Hg concentrations in water samples were less than the U.S. Environmental Protection Agency (USEPA) Hg chronic aquatic life criterion of 12 ng/L.The USEPA recommended a water-quality criterion of 0.30 milligrams per kilogram (mg/kg) methylmercury (MeHg) expressed as a fish-tissue residue value (wet-weight MeHg in fish tissue). The Idaho Department of Environmental Quality adopted the USEPA’s fish-tissue criterion and established a reasonable potential to exceed (RPTE) threshold 20 percent lower than the criterion or greater than 0.24 mg/kg Hg based on an average concentration of 10 fish from a receiving waterbody. NPDES permitted discharge to waters with fish having Hg concentrations exceeding 0.24 mg/kg are said to have a reasonable potential to exceed the water-quality criterion and thus are subject to additional permit obligations, such as requirements for increased monitoring and the development of a Hg minimization plan. The Idaho Fish Consumption Advisory Program (IFCAP) issues fish advisories to protect general and sensitive populations of fish consumers and has developed an action level of 0.22 mg/kg Hg in fish tissue. Fish consumption advisories are water body- and species-specific and are used to advise allowable fish consumption from specific water bodies.

    Phase III began in 1995 with the overall goal of quantifying changes in resident fish habitat in the Snake River basin upstream of Brownlee Reservoir resulting from the release of salmon flow augmentation water. Existing data, in the form of weighted usable area versus flow relationships, were used to estimate habitat changes for white sturgeon (Acipenser transmontanus) and rainbow trout (Oncorhynchus mykiss)in the Snake River between C.J. Strike Dam and Brownlee pool. The increased flows resulted in increased white sturgeon habitat for most life stages. Rainbow trout adult and spawning habitat increased while juvenile and fry habitat generally decreased. Whether or not these short term increases in habitat result in long term benefits to the fish populations has yet to be determined.

Both fish screen facilities were examined to determine if they were being effectively operated and maintained to provide for safe fish passage. At the Nursery Bridge Fishway, the screens were evaluated specifically to determine whether the louvers that aid in controlling water flow from behind the screens could be adjusted so that the screens would meet fish protection criteria. Data were collected to determine whether velocities in front of the screens and in the bypasses met current National Oceanic and Atmospheric Administration Fisheries (NOAA Fisheries) (formerly National Marine Fisheries Service (NMFS)) criteria to promote safe and timely fish passage before and after changing the louver settings. Rock weirs downstream of the dam were also evaluated to determine whether they might impede upstream migration of juvenile salmonids during low flow conditions. At the Garden City/Lowden II site, data were collected to establish a baseline for operating conditions and to determine whether any changes in the baffle settings were needed.

    Bonneville Power Administration (BPA), Department of Energy (DOE), is proposing to fund the Idaho Department of Fish and Game (IDFG) Captive Rearing Initiative for Salmon River Chinook Salmon Program (IDFG Program). The IDFG Program is a small-scale research and production initiative designed to increase numbers of three weak but recoverable populations of spring/summer chinook salmon in the Salmon River drainage. This would increase numbers of spring/summer chinook salmon within the Snake River Spring/Summer Chinook Salmon Evolutionarily Significant Unit (ESU), and reduce population fragmentation within the ESU. BPA has prepared an Environmental Assessment (EA) (DOE/EA-1301) evaluating the proposed IDFG Program. Based on the analysis in the EA, BPA has determined that the Proposed Action is not a major Federal action significantly affecting the quality of the human environment, as defined within the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an Environmental Impact Statement (EIS) is not required, and BPA is issuing this Finding of No Significant Impact (FONSI).

    Phase 3 began in 1995 with the overall goal of quantifying changes in resident fish habitat in the Snake River Basin upstream of Brownlee Reservoir resulting from the release of salmon flow augmentation water. Existing data, in the form of weighted usable area versus flow relationships, were used to estimate habitat changes for white sturgeon (Acipenser transinontanus) and rainbow trout (Oncorhynchus mykiss) in the Snake River between C.J. Strike Dam and Brownlee pool. The increased flows resulted in increased habitat for adult and juvenile white sturgeon and adult rainbow trout. But, the flows have failed to meet mean monthly flow recommendations for the past three years despite the addition of the flow augmentation releases. It is unlikely that the flow augmentation releases have had any significant long-term benefit for sturgeon and rainbow trout in the Snake River. Flow augmentation releases from the Boise and Payette rivers have in some years helped to meet or exceed minimum flow recommendations in these tributaries. The minimum flows would not have been reached without the flow augmentation releases. But, in some instances, the timing of the releases need to be adjusted in order to maximize benefits to resident fishes in the Boise and Payette rivers.

    We evaluated the effectiveness of new fish screening facilities in the Westside Ditch and Wapato Canal in south-central Washington State. The screen integrity tests indicated that test fish released in front of the screens could enter the canal behind the screens. At Westside Ditch, between 6% and 25% of the zero-age fry passed through the rotary drum screens. The 6% estimate is based on tests with rainbow trout Oncorhynchus mykiss fry. The 25% estimate is based on monitoring chinook salmon 0. tshawytscha fry that were diverted from the river into the irrigation ditch. At Westside Ditch, we estimated that 1.8% of steelhead 0. mykiss smolts and 0.3% of chinook salmon smolts released during tests were descaled. The time required for 50% of the test fish to exit from the Westside Ditch Screen forebay was 3 to 8 h for chinook salmon smolts and up to 28 h for steelhead smolts. Methods used in 1988 were first used at Sunnyside in 1985 and were used in subsequent years at Richland. Toppenish/Satus. Wapato. and Toppenish Creek.

The program provides offsite enhancement to compensate for fish and wildlife losses caused by hydroelectric development throughout the Columbia River Basin, and addresses natural propagation of salmon to help mitigate the impact of irrigation in the Yakima River Basin. This report evaluates the flow characteristics of the screening facilities. Studies consisted of velocity measurements taken in front of the rotary drum screens and within the fish bypass systems during peak flows. Measurements of approach velocity and sweep velocity were emphasized in these studies; however, vertical velocity was also measured. 5 refs., 18 figs., 15 tabs.

    The fisheries evaluation phase of diversion screen effectiveness summarizes the results of work at the Richland and Toppenish/Satus Fish screening facilities (Richland Screens and Toppenish/Satus Screens) during 1986. More than 10,000 steelhead, Salmo gairdneri, and chinook salmon, Oncorhynchus tshawytscha, were released at the screen diversions. At the Richland Screens, 61% of the released steelhead were recovered and 1.1% were descaled; 93% of the spring chinook salmon were recovered and less than 1% were descaled. At the Toppenish/Satus Screens, only steelhead were evaluated for descaling; 88.9% were recovered and 23.9% were descaled. Only steelhead were evaluated because the Yakima River fisheries managers did not expect any other smolts to occur in Toppenish Creek. Because of the acclimation conditions and the amount of time the fish had to be held before testing, some of the test population were descaled during holding and transportation. The 23.9% descaling for the test fish was compared to 26.4% for the controls.

    Fish tissue and bed sediment samples were collected from 16 stream sites in the Northern Rockies Intermontane Basins study area in 1998 as part of the U.S. Geological Survey National Water-Quality Assessment Program. Bed sediment samples were analyzed for 45 trace elements, and fish livers and sportfish fillets were analyzed for 22 elements to characterize the occurrence and distribution of these elements in relation to stream characteristics and land use activities. Nine trace elements of environmental concern—arsenic, cadmium, chromium, copper, lead, mercury, nickel, selenium, and zinc—were detected in bed sediment, but not all of these elements were detected in fish tissue. Trace-element concentrations were highest in bed sediment samples collected at sites downstream from significant natural mineral deposits and (or) mining activities. Arsenic, cadmium, copper, lead, mercury, and zinc in bed sediment at some sites were elevated relative to national median concentrations, and some concentrations were at levels that can adversely affect aquatic biota. Although trace-element concentrations in bed sediment exceeded various guidelines, no concentrations in sportfish fillets exceeded U.S. Environmental Protection Agency screening values for the protection of human health. Correlations between most trace-element concentrations in bed sediment and fish tissue (liver and fillet) were not significant (r0.05). Concentrations of arsenic, cadmium, copper, lead, mercury, nickel, selenium, and zinc in bed sediment were significantly correlated (r=0.53 to 0.88, p2=0.95 and 0.99, p<0.001) that corresponded to trace-element enrichment categories. These strong relations warrant further study using mine density as an explanatory variable to predict trace-element concentrations in bed sediment.

    In 2004, the Pacific Northwest National Laboratory (PNNL) evaluated 25 Phase II fish screen sites in the Yakima River Basin as part of a multi-year project for the Bonneville Power Administration on the effectiveness of fish screening devices. PNNL collected data to determine whether velocities in front of the screens and in the bypasses met the National Oceanic and Atmospheric Administration Fisheries (NOAA Fisheries, formerly the National Marine Fisheries Service (NMFS)) criteria to promote safe and timely fish passage. In addition, PNNL conducted underwater video surveys to evaluate the environmental and operational conditions of the screen sites with respect to fish passage. Based on evaluations in 2004, PNNL concluded that: (1) In general, water velocity conditions at the screen sites met fish passage criteria set by NOAA Fisheries. (2) Conditions at most facilities would be expected to provide for safe juvenile fish passage. (3) Automated cleaning brushes generally functioned properly; chains and other moving parts were typically well-greased and operative. (4) Removal of sediment buildup and accumulated leafy and woody debris could be improved at some sites. (5) Conditions at some facilities indicate that operation and/or maintenance should be modified to improve passage conditions for juvenile fish. For example, Taylor has had problems meeting bypass flow and submergence operating criteria since the main river channel shifted away from the site 2 years ago, and Fruitvale consistently has had problems meeting bypass flow criteria when the water is low.

    In 2005, Pacific Northwest National Laboratory (PNNL) researchers evaluated 25 Phase II fish screen sites in the Yakima and Touchet river basins. Pacific Northwest National Laboratory performs these evaluations for Bonneville Power Administration (BPA) to determine whether the fish screening devices meet National Marine Fisheries Service (NMFS) criteria to promote safe and timely fish passage. Evaluations consist of measuring velocities in front of the screens, using an underwater camera to look at the condition and environment in front of the screens, and noting the general condition and operation of the sites. Results of the evaluations in 2005 include the following: (1) Most approach velocities met the NMFS criterion of less than or equal to 0.4 fps. Less than 13% of all approach measurements exceeded the criterion, and these occurred at 10 of the sites. Flat-plate screens had more problems than drum screens with high approach velocities. (2) Bypass velocities generally were greater than sweep velocities, but sweep velocities often did not increase toward the bypass. The latter condition could slow migration of fish through the facility. (3) Screen and seal materials generally were in good condition. (4) Automated cleaning brushes generally functioned properly; chains and other moving parts were typically well-greased and operative. (5) Washington Department of Fish and Wildlife (WDFW) and U.S. Bureau of Reclamation (USBR) generally operate and maintain fish screen facilities in a way that provides safe passage for juvenile fish. (6) In some instances, irrigators responsible for specific maintenance at their sites (e.g., debris removal) are not performing their tasks in a way that provides optimum operation of the fish screen facility. New ways need to be found to encourage them to maintain their facilities properly. (7) We recommend placing datasheets providing up-to-date operating criteria and design flows in each sites logbox.

    Fish screens can help prevent the entrainment or injury of fish at irrigation diversions, but only when designed appropriately. Design criteria cannot simply be transferred between sites or pump systems and need to be developed using an evidence-based approach with the needs of local species in mind. Laboratory testing is typically used to quantify fish responses at intake screens, but often limits the number of species that can studied and creates artificial conditions not directly applicable to screens in the wild. In this study a field-based approach was used to assess the appropriateness of different screen design attributes for the protection of a lowland river fish assemblage at an experimental irrigation pump. Direct netting of entrained fish was used along with sonar technology to quantify the probability of screen contact for a Murray-Darling Basin (Australia) fish species. Two approach velocities (0.1 and 0.5 m.sec(-1)) and different sizes of woven mesh (5, 10 and 20 mm) were evaluated. Smaller fish (<150 mm) in the assemblage were significantly more susceptible to entrainment and screen contact, especially at higher approach velocities. Mesh size appeared to have little impact on screen contact and entrainment, suggesting that approach velocity rather than mesh size is likely to be the primary consideration when developing screens. Until the effects of screen contacts on injury and survival of these species are better understood, it is recommended that approach velocities not exceed 0.1 m.sec(-1) when the desire is to protect the largest range of species and size classes for lowland river fish assemblages in the Murray-Darling Basin. The field method tested proved to be a useful approach that could compliment laboratory studies to refine fish screen design and facilitate field validation.

    The utility of a fish DNA damage assay as a rapid monitoring tool was investigated. Metal plating wastewater was chosen as a sample because it contains various genotoxic metal species. Fish DNA damage assay results were compared to data generated from the conventional whole effluent toxicity (WET) test procedure. The Microtox{reg_sign} assay (Azur Environmental, Carlsbad, CA, USA) using Vibrio fischeri was also employed. Eleven samples from two metal plating companies were collected for this evaluation. For the fish DNA damage assay, 7-d-old fathead minnow larvae, Pimephales promelas, were utilized. They were exposed to a series of dilutions at 20 C for 2 h. Whole effluent toxicity tests conducted in this study included two acute toxicity tests with Daphnia magna and fathead minnows and two chronic toxicity tests with Ceriodaphnia dubia and fathead minnows. The fish DNA damage assay showed good correlations with both the acute and chronic WET test results, especially with those obtained with fathead minnows. The kappa values, an index of agreement, between the fish DNA damage assay and WET tests were shown to be acceptable. These findings imply that this novel fish DNA damage assay has use as an expedient toxicity screening procedure since it produces comparable results to those of the acute and chronic fathead minnow toxicity tests.

The fish-screen facilities were examined to determine if they were being effectively operated and maintained to provide for safe fish passage. At the Nursery Bridge Fishway, the screens were evaluated specifically to determine whether the louvers that aid in controlling water flow from behind the screens could be adjusted so that the screens would meet fish-protection criteria. Data were collected to determine whether velocities in front of the screens met current National Oceanic and Atmospheric Administration's National Marine Fisheries Service (NOAA Fisheries) (formerly NMFS) criteria to promote safe and timely fish passage before and after changing the louver settings. The Little Walla Walla screens were evaluated to determine how a build-up of algae on the screens affected water velocities.

    In 2007, Pacific Northwest National Laboratory was asked by the U.S. Bureau of Reclamation to provide additional velocity measurements at Gleed fish screens site to support decisions on mitigating extreme flow fluctuations near the screens. The site consistently has had extreme water velocities in places and a strong back eddy at the downstream end in spring and summer. With the help of Washington Department of Fish and Wildlife staff, we measured the effects of different stoplog configurations behind the screens in May and July 2007. Protective metal plates in front of the trash racks were confirmed to be the cause of uneven and extreme water flow past the vertical traveling screens. Stoplogs were not sufficient to significantly reduce the effect of those metal plates on water velocities past and through the site. We provide a few suggestions including making it easier to raise and lower the metal plates and then adjusting them more often, constructing a new trash rack across the diversion entrance, and raising the control gate at the end of the site as long as possible in spring and during flood events.

    A pilot exposure study was conducted to determine whether the consumption of fish captured in Lake Coeur d'Alene (LCD), the Coeur d'Alene River, and the adjacent Chain Lakes, could substantially increase lead and cadmium levels in human blood and urine. The goals of the study were: to characterize fish and duck consumption patterns of people living around LCD; and to determine the association between fish and duck consumption and lead/cadmium levels. The lead and cadmium levels among participants living near LCD were within the expected range and are not of any known clinical importance. After adjusting for age and smoking, it was found that persons eating fish or duck were more likely to have higher than the median levels of cadmium in their urine. There were no statistically significant associations between fish or duck consumption and blood levels of lead or cadmium or urine levels of cadmium when adjusted for creatinine.

    This study evaluated the clinical significance of hTERC gene amplification detection by fluorescence in situ hybridization (FISH) in the screening of cervical lesions. Cervical specimens of 50 high risk patients were detected by thin liquid-based cytology. The patients whose cytological results were classified as ASCUS or above were subjected to the subsequent colposcopic biopsies. Slides prepared from these 50 cervical specimens were analyzed for hTERC gene amplification using interphase FISH with the two-color hTERC probe. The results of the cytological analysis and those of subsequent biopsies, when available, were compared with the FISH-detected hTERC abnormalities. It was found that the positive rates of hTERC gene amplification in NILM, ASCUS, LSIL, HSIL, and SCC groups were 0.00, 28.57%, 57.14%, 100%, and 100%, respectively. The positive rates of hTERC gene amplification in HSIL and SCC groups were significantly higher than those in NILM, ASCUS and LSIL groups (all P<0.05). The mean percentages of cells with hTERC gene amplification in NILM, ASCUS, LSIL, HSIL, and SCC groups were 0.00, 10.50%, 36.00%, 79.00%, and 96.50%, respectively. Patients with HSIL or SCC cytological diagnoses had significantly higher mean percentages of cells with hTERC gene amplification than did patients with NILM, ASCUS or LSIL cytological diagnoses (all P<0.05). It was concluded that two-color interphase FISH could detect hTERC gene amplification to accurately distinguish HSIL and ISIL of cervical cells. It may be an adjunct to cytology screening, especially high-risk patients.

    Viral hemorrhagic septicemia virus (VHSV) infects a wide range of marine fish species. To study the occurrence of VHSV in wild marine fish populations in Norwegian coastal waters and fjord systems a total of 1927 fish from 39 different species were sampled through 5 research cruises conducted in 2009 to 2011. In total, VHSV was detected by rRT-PCR in twelve samples originating from Atlantic herring (Clupea harengus), haddock (Melanogrammus aeglefinus), whiting (Merlangius merlangus) and silvery pout (Gadiculus argenteus). All fish tested positive in gills while four herring and one silvery pout also tested positive in internal organs. Successful virus isolation in cell culture was only obtained from one pooled Atlantic herring sample which shows that today's PCR methodology have a much higher sensitivity than cell culture for detection of VHSV. Sequencing revealed that the positive samples belonged to VHSV genotype Ib and phylogenetic analysis shows that the isolate from Atlantic herring and silvery pout are closely related. All positive fish were sampled in the same area in the northern county of Finnmark. This is the first detection of VHSV in Atlantic herring this far north, and to our knowledge the first detection of VHSV in silvery pout. However, low prevalence of VHSV genotype Ib in Atlantic herring and other wild marine fish are well known in other parts of Europe. Earlier there have been a few reports of disease outbreaks in farmed rainbow trout with VHSV of genotype Ib, and our results show that there is a possibility of transfer of VHSV from wild to farmed fish along the Norwegian coast line. The impact of VHSV on wild fish is not well documented. PMID:25248078

    2002-11-01

    A method is presented for fluorescence in situ hybridization (FISH) of 16S rRNA gene clones targeting in vivo transcribed plasmid inserts (Clone-FISH). Several different cloning approaches and treatments to generate target-rRNA in the clones were compared. Highest signal intensities of Clone-FISH were obtained using plasmids with a T7 RNA polymerase promoter and host cells with an IPTG-inducible T7 RNA polymerase. Combined IPTG-induction and chloramphenicol treatment of those clones resulted in FISH signals up to 2.8-fold higher than signals of FISH with probe EUB338 to cells of Escherichia coli. Probe dissociation curves for three oligonucleotide probes were compared for reference cells containing native (FISH) or cloned (Clone-FISH) target sequences. Melting behaviour and calculated T(d) values were virtually identical for clones and cells, providing a format to use 16S rRNA gene clones instead of pure cultures for probe validation and optimization of hybridization conditions. The optimized Clone-FISH protocol was also used to screen an environmental clone library for insert sequences of interest. In this application format, 13 out of 82 clones examined were identified to contain sulphate-reducing bacterial rRNA genes. In summary, Clone-FISH is a simple and fast technique, compatible with a wide variety of cloning vectors and hosts, that should have general utility for probe validation and screening of clone libraries.

    This report was prepared by the Pacific Northwest National Lab., Richland, Washington, BAE Systems, Inc., a subcontractor to the U.S. Army Engineer Research and Development Center (ERDC), Vicksburg, Mississippi. This study examined the effect of gatewell modifications on the proportion of fish lost through the gap between the top of submerged traveling screens (STSs) and the ceilings of intakes in one un-modified and two modified turbine units at Bonneville Dam Second Powerhouse (B2). Combined modifications reduced the proportion of flow through the gap from 44% to 16% and increased the proportion moving up the gatewell from 56% to 84%. We used a Dual-Frequency Identification Sonar (DIDSON) acoustic camera to record proportions of juvenile salmonids moving up into the gatewell and through the gap. The acoustic camera was used to record images of fish passing up into the gatewell and through the gap for 8-h on three successive nights in every intake of units 13, 15, and 17 (i.e., 9 intakes x 3 nights = 27 nights each season). Only 28.6% of the objects detected in spring and 12.9% in summer were determined to be fish. Other objects included sticks and debris. Although the true magnitude of STS gap-loss is unknown, both acoustic camera and netting estimates indicate that gatewell modifications reduce relative gap loss by about 67%.

    The Bonneville Power Administration is proposing to fund a fish passage improvement project at the L-9 diversion on the Lemhi River in Lemhi County, Idaho with the Lemhi Soil and Water Conservation District. The project proposes to replace the existing rock push-up irrigation diversion dam with a single rock weir that will incorporate a geotextile membrane to create a permanent diversion. The new weir will be a v-shaped vortex weir with a six-foot wide notch for fish passage. In addition, a ramp flume will be constructed in the diversion canal between the headgate and existing fish screen to provide for water measurement. The new diversion will provide better water delivery/control and improved passage for adult and juvenile resident and anadromous fish.

    Arsenic, Cd, Cu, Pb, Hg, and Zn were measured in sediments, biofilm, benthic macroinvertebrates, and fish from the Coeur d'Alene (CDA) River to characterize the pathway of metals transfer between these components. Metals enter the CDA Basin via tributaries where mining activities have occurred. In general, the ranking of food-web components from the greatest to smallest concentrations of metals was as follows: biofilm (the layer of abiotic and biotic material on rock surfaces) and sediments > invertebrates > whole fish. Elevated Pb was documented in invertebrates, and elevated Cd and Zn were documented in sediment and biofilm approximately 80 km downstream to the Spokane River. The accumulation of metals in invertebrates was dependent on functional feeding group and shredders-scrapers that feed on biofilm accumulated the largest concentrations of metals. Although the absolute concentrations of metals were the largest in biofilm and sediments, the metals have accumulated in fish approximately 50 km downstream from Kellogg, near the town of Harrison. While metals do not biomagnify between trophic levels, the metals in the CDA Basin are bioavailable and do biotransfer. Trout less than 100 mm long feed exclusively on small invertebrates, and small invertebrates accumulate greater concentrations of metals than large invertebrates. Therefore, early-lifestage fish may be exposed to a larger dose of metals than adults.

    Temperature is a critical factor in stream ecosystems, and one that is very likely to be altered by wildfire and associated channel disturbance. In central Idaho streams, temperatures after wildfires may increase following loss of shade from riparian vegetation, and changes in channel structure that increase exposure to solar radiation and decreased hyporheic exchanges. To examine the spatio-temporal aspects temperature in relation to these influences, we employed three approaches: a long-term pre-post fire comparison of temperatures between a pair of streams, one burned and one unburned; a short-term pre-post fire comparison of a burned and unburned stream with spatially extensive data; a short-term comparative study of spatial variability in temperatures using a "space for time" substitutive design. These three approaches provided key insights into the value of each study approach and revealed some expected and some surprising associations between temperature and occurrence of native trout and tailed frogs. To further understand potential mechanisms influencing stream temperature, we used field-validated estimates of solar radiation to model the effects of riparian shade from remotely sensed vegetation data. These models confirmed the importance of riparian influences linked to wildfire for stream temperature in our study system. The collective results of this work highlight the importance of spatio-temporal variability in study designs to quantify the effects of wildfire and disturbance on stream temperatures, and the implications of stream temperature for aquatic species in a broad landscape context.

    A study to determine the occurrence and distribution of trace elements, organochlorine pesticides, polychlorinated biphenyls (PCBs), and semivolatile organic compounds in sediment and in fish tissue was conducted in the Great Salt Lake Basins study unit of the National Water-Quality Assessment (NAWQA) program during 1998-99. Streambed-sediment and fish-tissue samples were collected concurrently at 11 sites and analyzed for trace-element concentration. An additional four sites were sampled for streambed sediment only and one site for fish tissue only. Organic compounds were analyzed from streambed-sediment and fish-tissue samples at 15 sites concurrently. Bed-sediment cores from lakes, reservoirs, and Farmington Bay collected by the NAWQA program in 1998 and by other researchers in 1982 were used to examine historical trends in trace-element concentration and to determine anthropogenic sources of contaminants. Cores collected in 1982 from Mirror Lake, a high-mountain reference location, showed an enrichment of arsenic, cadmium, copper, lead, tin, and zinc in the surface sediments relative to the deeper sediments, indicating that enrichment likely began after about 1900. This enrichment was attributed to atmospheric deposition during the period of metal-ore mining and smelting. A core from Echo Reservoir, in the Weber River Basin, however, showed a different pattern of trace-element concentration that was attributed to a local source. This site is located downstream from the Park City mining district, which is the most likely historical source of trace elements. Cores collected in 1998 from Farmington Bay show that the concentration of lead began to increase after 1842 and peaked during the mid-1980s and has been in decline since. Recent sediments deposited during 1996-98 indicate a 41- to 62-percent reduction since the peak in the mid-1980s. The concentration of trace elements in streambed sediment was greatest at sites that have been affected by historic mining

    Diabetes mellitus affects millions of people worldwide and significantly impacts their quality of life. Moreover, life threatening diseases, such as myocardial infarction, blindness, and renal disorders, increase the morbidity rate associated with diabetes. Various natural products from medicinal plants have shown potential as antidiabetes agents in cell-based screening systems. However, many of these potential "hits" fail in mammalian tests, due to issues such as poor pharmacokinetics and/or toxic side effects. To address this problem, the zebrafish (Danio rerio) model has been developed as a "bridge" to provide an experimentally convenient animal-based screening system to identify drug candidates that are active in vivo. In this review, we discuss the application of zebrafish to drug screening technologies for diabetes research. Specifically, the discovery of natural product-based antidiabetes compounds using zebrafish will be described. For example, it has recently been demonstrated that antidiabetic natural compounds can be identified in zebrafish using activity guided fractionation of crude plant extracts. Moreover, the development of fluorescent-tagged glucose bioprobes has allowed the screening of natural product-based modulators of glucose homeostasis in zebrafish. We hope that the discussion of these advances will illustrate the value and simplicity of establishing zebrafish-based assays for antidiabetic compounds in natural products-based laboratories.

    Pacific Northwest National Laboratory (PNNL) evaluated two fish screen facilities in the Walla Walla River basin in 2005 and early 2006. The Garden City/Lowden screen site was evaluated in April and June 2005 to determine whether the fish screens met National Marine Fisheries Service criteria to provide safe passage for juvenile salmonids. Louvers behind the screens at the Nursery Bridge Fishway were modified in fall 2005 in an attempt to minimize high approach velocities. PNNL evaluated the effects of those modifications in March 2006. Results of the Garden City/Lowden evaluations indicate the site performs well at varying river levels and canal flows. Approach velocities did not exceed 0.4 feet per second (fps) at any time. Sweep velocities increased toward the fish ladder in March but not in June. The air-burst mechanism appears to keep large debris off the screens, although it does not prevent algae and periphyton from growing on the screen face, especially near the bottom of the screens. At Nursery Bridge, results indicate all the approach velocities were below 0.4 fps under the moderate river levels and operational conditions encountered on March 7, 2006. Sweep did not consistently increase toward the fish ladder, but the site generally met the criteria for safe passage of juvenile salmonids. Modifications to the louvers seem to allow more control over the amount of water moving through the screens. We will measure approach velocities when river levels are higher to determine whether the louver modifications can help correct excessive approach velocities under a range of river levels and auxiliary water supply flows.

    The antibacterial activity of ethanolic and aqueous crude extracts from 36 plants in Turkey, including seven endemic species, against fish pathogens was studied using the disc diffusion assay. The extract that was most active against all microbial strains, except Aeromonas salmonicida, was that of Dorycnium pentaphyllum. Some of the extracts also showed a very broad spectrum of potent antimicrobial activity. The extract of Anemone nemorosa showed the highest antimicrobial activity against Vibrio anguillarum. V. anguillarum, a Gram-negative bacterium, appeared to be the most susceptible to the plant extracts used in this experiment. To the best of our knowledge, this is the first report on the antimicrobial activity of 11 of the studied plants. The preliminary screening assay indicated that some of the Turkish plants with antibacterial properties may offer alternative therapeutic agents against bacterial infections in aquaculture industry.

    Chemical warfare agents (CWAs) have been disposed of in various fashions over the past decades. Significant amounts (approximately 11,000 tonnes) have been dumped in the Baltic Sea east of the island Bornholm following the disarmament of Germany after World War II, causing concerns over potential environmental risks. Absence of risk based on assumptions of extremely low solubility of CWAs cannot alone dismiss these concerns. Existing and modelled fate and effects data were used in the analysis to assess the fish community risk level. The most realistic and also conservative assessment result is the scenario describing 70 m water depth for the most realistic dump-site area with a focus on chronic toxicity, at 0-20 cm above the sediment, yielding a total mixture toxic unit (TU) of 0.62. Triphenylarsine is the CWA with the highest realistic risk profile at 0.2 TU for the fish community followed by Adamsite (0.17), Clark I (0.086) and Yperite (0.083) TU. Adamsite is more persistent and constitutes a potential risk for a longer period than triphenylarsine. The seawater volume potentially at risk is <4 m above sediment and <58 km down current of dump sites. Further risk assessment of dumped CWAs in the Baltic Sea is warranted.

    Numerical chromosome aberrations are incompatible with normal human development. Our laboratories develop hybridization based screening tools that generate a maximum of cytogenetic information for each polar body or blastomere analyzed. The methods are developed considering that the abnormality might require preparation of case-specific probes and that only one or two cells will be available for diagnosis, most of which might be in the interphase stage. Further more, assay efficiencies have to be high, since there is typically not enough time to repeat an experiment or reconfirm a result prior to fertilization or embryo transfer. Structural alterations are delineated with break point-spanning probes. When screening for numerical abnormalities, we apply a Spectral Imaging-based approach to simultaneously score as many as ten different chromosome types in individual inter phase cells. Finally, DNA micro-arrays are under development to score all of the human chromosomes in a single experiment and to increase the resolution with which micro-deletions can be delineated.

    The Pacific Northwest National Laboratory (PNNL) evaluated the effectiveness of 6-in. and 2-in. submerged orifices, and an overflow weir for fish bypass at a rotary drum fish screening facility. A modular drum screen built by the Washington Department of Fish and Wildlife (WDFW) was installed at PNNL`s Aquatic Ecology research laboratory in Richland, Washington. Fry, subyearlings, and smolts of spring chinook salmon (Oncorhynchus tshawyacha) were introduced into the test system, and their movement and injury rates were monitored. A total of 33 tests (100 fish per test) that lasted from 24 to 48 hr were completed from 1994 through 1995. Passage rate depended on both fish size and bypass configuration. For fry/fingerling spring chinook salmon, there was no difference in passage rate through the three bypass configurations (2-in. orifice, 6-in. orifice, or overflow weir). Subyearlings moved sooner when the 6-in. orifice was used, with more than 50% exiting through the fish bypass in the first 8 hr. Smolts exited quickly and preferred the 6-in. orifice, with over 90% of the smolts exiting through the bypass in less than 2 hr. Passage was slightly slower when a weir was used, with 90% of the smolts exiting in about 4 hr. When the 2-in. orifice was used in the bypass, 90% of the smolts did not exit until after 8 hr. In addition, about 7% of the smolts failed to migrate from the forebay within 24 hr, indicating that smolts were significantly delayed when the 2-in. orifice was used. Few significant injuries were detected for any of the life stages. However, light descaling occurred on about 15% of chinook salmon smolts passing through the 2-in. orifice. Although a single passage through the orifice did not appear to cause significant scale loss or other damage, passing through several screening facilities with 2-in. orifices could cause cumulative injuries.

    Since 1986 Washington Department of Fisheries (WDF) has participated in the Columbia Basin Augmented Fish Health Monitoring Project, funded by Bonneville Power Administration (BPA). This interagency project was developed to provide a standardized level of fish health information from all Agencies rearing fish in the Columbia Basin. Agencies involved in the project are: WDF, Washington Department of Wildlife, Oregon Fish and Wildlife, Idaho Fish and Game, and the US Fish and Wildlife Service. WDF has actively participated in this project, and completed its third year of fish health monitoring, data collection and pathogen inspection during 1989. This report will present data collected from January 1, 1989 to December 31, 1989 and will compare sampling results from screening at spawning for viral pathogens and bacterial kidney disease (BKD), and evaluation of causes of pre-spawning loss. The juvenile analysis will include pre-release examination results, mid-term rearing exam results and evaluation of the Organosomatic Analysis completed on stocks. 2 refs., 4 figs., 15 tabs.

    The possibility of direct measurement of trace elements in hepatic cytosol of European chub (Squalius cephalus) by high-resolution inductively coupled plasma mass spectrometry (HR ICP-MS) after cytosol dilution with Milli-Q water and subsequent acidification was investigated. Due to low detection limits of this procedure, determination of 13 elements (As, Cd, Co, Cu, Fe, Mn, Mo, Pb, Sb, Sn, Sr, V and Zn) was possible in the chub hepatic cytosol, exhibiting excellent measurement repeatability in duplicates. Some of these elements were also measured by HR ICP-MS in acid digested cytosols (Cd, Co, Cu, Fe, Mn, Mo, Sr, V and Zn). Good agreement of the results obtained after sample dilution and sample digestion indicated that complex organic matrix of hepatic cytosol did not affect measurement reliability. Cytosolic concentrations of 13 trace elements in the chub liver were quantified in the following order: Fe, Zn>Cu>Mn>Mo>Sr, V, Cd>Co>As, Pb>Sn>Sb. Unlike Cd, Cu, Fe, Mn and Zn for which the cytosolic concentrations were previously reported after measurement by AAS, cytosolic concentrations of eight additional trace elements characteristic for the liver of chubs inhabiting the low contaminated river water were reported here for the first time (in nanogrammes per gramme)-Mo, 136.8-183.6; Sr, 32.7-63.0; V, 17.5-69.0; Co, 24.3-30.7; As, 9.9-29.5; Pb, 5.8-35.6; Sn, 5.5-12.4; and Sb, 0.9-2.6. The simultaneous measurement of large number of trace elements in the cytosolic fractions of fish tissues, which comprise potentially metal-sensitive sub-cellular pools, could be beneficial as a screening tool in the monitoring of natural waters, because it would enable timely recognition of increased fish exposure to metals.

    A fire protection survey was conducted for the Department of Energy at the Westinghouse Idaho Nuclear Company, INC., Idaho Falls, Idaho, on April 24--27, April 30--May 4, June 4--8, and June 11--15, 1990. The purpose of the survey was to review the facility's fire protection program and to make recommendations according to the following criteria established by the Department of Energy: (1) Recommendations which would be made as the result of an improved risk or Highly Protected Risk (HPR) fire inspection of an industrial insured facility. (2) Identification of areas which are presently not protected or are inadequately protected where provision of automatic protection would reduce a fire or explosion loss to less than $1 million. (3) Identification of areas where loss potentials exceed $50 million assuming a failure of automatic protection systems and subsequent reliance only on separation and fire walls. (4) Evaluation of adequacy of compliance with recommendations made in prior surveys. Findings and recommendations in this report reflect to some degree the relative importance of the operation and the time to restore it to useful condition in the event that a loss were to occur.

  14. Cross-species conservation of endocrine pathways: a critical analysis of tier 1 fish and rat screening assays with 12 model chemicals.

    Many structural and functional aspects of the vertebrate hypothalamic-pituitary-gonadal (HPG) axis are known to be highly conserved, but the significance of this from a toxicological perspective has received comparatively little attention. High-quality data generated through development and validation of Tier 1 tests for the U.S. Environmenal Protection Agency Endocrine Disruptor Screening Program (EDSP) offer a unique opportunity to compare responses of mammals versus fish to chemicals that may affect shared pathways within the HPG axis. The present study focuses on data generated with model chemicals that act (primarily) as estrogen receptor agonists (17α-ethynylestradiol, methoxychlor, bisphenol A), androgen receptor agonists (methyltestosterone, 17β-trenbolone), androgen receptor antagonists (flutamide, vincolozolin, p,p'-DDE), or inhibitors of different steroidogenic enzymes (ketoconazole, fadrozole, fenarimol, prochloraz). All 12 chemicals had been tested in the EDSP fish short-term (21 d) reproduction assay and in one or more of the four in vivo Tier 1 screens with rats (uterotrophic, Hershberger, male and female pubertal assays). There was a high concordance between the fish and rat assays with respect to identifying chemicals that impacted specific endocrine pathways of concern. Although most chemicals were detected as positive in both rat and fish assays, eliminating data from one class of vertebrate or the other would weaken the battery. For example, the effects of competitive inhibitors of steroid hormone synthesis were far more obvious in the fish assay, whereas the activity of androgen receptor antagonists was clearer in mammalian assays. The observations are significant both to the cross-species extrapolation of toxicity of HPG-active substances and the optimization of screening and testing frameworks for endocrine-disrupting chemicals.

    The present study represents the first molecular-chemical screening by pyrolysis-field ionization mass spectrometry applied on fish parasites. A total of 71 fishes from Balinese fish markets, 36 Auxis rochei (Risso, 1810) and 35 A. thazard (Lacepède, 1800), were studied for their acanthocephalan parasites. This is the first record of Rhadinorhynchus zhukovi in Balinese waters, Indonesia, and we describe for the first time A. rochei and A. thazard as R. zhukovi hosts. Using this method, small scale variations within the chemical compounds of acanthocephalans could be detected. Using this methodology it will be possible to generate additional, pollutant specific information from aquatic habitats in future with the potential of a new bioindicator application for parasite/host origin and/or environmental pollution.

    Endocrine disruption is considered a highly relevant hazard for environmental risk assessment of chemicals, plant protection products, biocides and pharmaceuticals. Therefore, screening tests with a focus on interference with estrogen, androgen, and thyroid hormone pathways in fish and amphibians have been developed. However, they use a large number of animals and short-term alternatives to animal tests would be advantageous. Therefore, the status of alternative assays for endocrine disruption in fish and frogs was assessed by a detailed literature analysis. The aim was to (i) determine the strengths and limitations of alternative assays and (ii) present conclusions regarding chemical specificity, sensitivity, and correlation with in vivo data. Data from 1995 to present were collected related to the detection/testing of estrogen-, androgen-, and thyroid-active chemicals in the following test systems: cell lines, primary cells, fish/frog embryos, yeast and cell-free systems. The review shows that the majority of alternative assays measure effects directly mediated by receptor binding or resulting from interference with hormone synthesis. Other mechanisms were rarely analysed. A database was established and used for a quantitative and comparative analysis. For example, a high correlation was observed between cell-free ligand binding and cell-based reporter cell assays, between fish and frog estrogenic data and between fish embryo tests and in vivo reproductive effects. It was concluded that there is a need for a more systematic study of the predictive capacity of alternative tests and ways to reduce inter- and intra-assay variability.

    The initial version (v1) of the Fish Invasiveness Scoring Kit (FISK) was adapted from the Weed Risk Assessment of Pheloung, Williams, and Halloy to assess the potential invasiveness of nonnative freshwater fishes in the United Kingdom. Published applications of FISK v1 have been primarily in temperate-zone countries (Belgium, Belarus, and Japan), so the specificity of this screening tool to that climatic zone was not noted until attempts were made to apply it in peninsular Florida. To remedy this shortcoming, the questions and guidance notes of FISK v1 were reviewed and revised to improve clarity and extend its applicability to broader climatic regions, resulting in changes to 36 of the 49 questions. In addition, upgrades were made to the software architecture of FISK to improve overall computational speed as well as graphical user interface flexibility and friendliness. We demonstrate the process of screening a fish species using FISK v2 in a realistic management scenario by assessing the Barcoo grunter Scortum barcoo (Terapontidae), a species whose management concerns are related to its potential use for aquaponics in Florida. The FISK v2 screening of Barcoo grunter placed the species into the lower range of medium risk (score = 5), suggesting it is a permissible species for use in Florida under current nonnative species regulations. Screening of the Barcoo grunter illustrates the usefulness of FISK v2 as a proactive tool serving to inform risk management decisions, but the low level of confidence associated with the assessment highlighted a dearth of critical information on this species.

    Chemical warfare agents (CWAs) have been disposed of in various fashions over the past decades. Significant amounts of CWA, roughly 11,000ton, have been dumped in the Baltic Sea east of the island Bornholm following the disarmament of Germany after World War II. This has caused concerns over potential human and environmental health risks, and resulted in restrictions on fishing in the dumpsite area. The purpose of this paper is to assess the potential indirect human health risks due to consumption of CWA-contaminated fish from the dumpsite area east of Bornholm. Earlier studies suggest that the fish community may be at risk from CWA exposure in the Bornholm basin. Moreover, elevated frequencies of lesions on fish caught in a CWA dumpsite in the Mediterranean Sea have been observed. The fish at the Mediterranean dumpsite had elevated total arsenic (As) concentrations in their tissue, and elevated total As levels were also observed in the sediment. Elevated total sediment As concentrations have also been recorded in CWA dumpsites in the Skagerrak and the Baltic Sea. Triphenylarsine and sulfur mustard gas (Yperite) are the CWAs with the greatest indirect human health risk potential. There are recognized uncertainties concerning Yperite's and CWA-derived arsenical's fate and speciation in the environment, as well as their inherent toxicity, warranting caution and further site-specific environmental and human health risk assessments of CWAs dumped in the Bornholm basin.

    Hollow fiber cell fishing, based on HepG-2, SKOV-3, and ACHN cancer cells, and hollow fiber liquid/solid microextraction with HPLC were developed and introduced for researching the anticancer activity of Rhizoma Curcumae Longae, Radix Curcumae, and Rhizoma Curcumae. The structures of curcumin, demethoxycurcumin, and bisdemethoxycurcumin screened were identified and their contents were determined. The compound target fishing factors and cell apoptosis rates under the effect of the three medicines were determined. The binding sites (cell membrane and cell organelle) and binding target (phospholipase C) on the cell were researched. Hollow fiber liquid/solid-phase microextraction mechanism was analyzed and expounded. Before the application, cell seeding time, growth state and survival rate, compound nonspecific binding, positive and negative controls, repeatability in hollow fiber cell fishing with high-performance liquid chromatography; extraction solvent, sample pH, salt concentration, agitation speed, extraction time, temperature and sample volume in hollow fiber liquid/solid-phase microextraction with high-performance liquid chromatography were investigated. The results demonstrated that the proposed strategy is a simple and quick method to identify bioactive compounds at the cellular level as well as determine their contents (particularly trace levels of the bioactive compounds), analyze multicompound and multitarget entirety effects, and elucidate the efficacious material base in traditional medicine.

    The goal of Idaho Steelhead Monitoring and Evaluation Studies is to collect monitoring data to evaluate wild and natural steelhead populations in the Clearwater and Salmon river drainages. During 2007, intensive population data were collected in Fish Creek (Lochsa River tributary) and Rapid River (Little Salmon River tributary); extensive data were collected in other selected spawning tributaries. Weirs were operated in Fish Creek and Rapid River to estimate adult escapement and to collect samples for age determination and genetic analysis. Snorkel surveys were conducted in Fish Creek, Rapid River, and Boulder Creek (Little Salmon River tributary) to estimate parr density. Screw traps were operated in Fish Creek, Rapid River, Secesh River, and Big Creek to estimate juvenile emigrant abundance, to tag fish for survival estimation, and to collect samples for age determination and genetic analysis. The estimated wild adult steelhead escapement in Fish Creek was 81 fish and in Rapid River was 32 fish. We estimate that juvenile emigration was 24,127 fish from Fish Creek; 5,632 fish from Rapid River; and 43,674 fish from Big Creek. The Secesh trap was pulled for an extended period due to wildfires, so we did not estimate emigrant abundance for that location. In cooperation with Idaho Supplementation Studies, trap tenders PIT tagged 25,618 steelhead juveniles at 18 screw trap sites in the Clearwater and Salmon river drainages. To estimate age composition, 143 adult steelhead and 5,082 juvenile steelhead scale samples were collected. At the time of this report, 114 adult and 1,642 juvenile samples have been aged. Project personnel collected genetic samples from 122 adults and 839 juveniles. We sent 678 genetic samples to the IDFG Eagle Fish Genetics Laboratory for analysis. Water temperature was recorded at 37 locations in the Clearwater and Salmon river drainages.

    The Idaho Explosives Detection System (IEDS) was developed at the Idaho National Laboratory (INL) to respond to threats imposed by delivery trucks carrying explosives into military bases. A full-scale prototype system has been built and is currently undergoing testing. The system consists of two racks, one on each side of a subject vehicle. Each rack includes a neutron generator and an array of NaI detectors. The two neutron generators are pulsed and synchronized. A laptop computer controls the entire system. The control software is easily operable by minimally trained staff. The system was developed to detect explosives in a medium size truck within a 5-minute measurement time. System performance was successfully demonstrated with explosives at the INL in June 2004 and at Andrews Air Force Base in July 2004.

    Two screening methods have been developed for simultaneous determination of ten extensively used personal care products (PCPs) and two alkylphenol surfactants in fish. The methods consisted of extraction, clean-up, derivatization and analysis by gas chromatography-mass spectrometry with selected ion monitoring (GC-SIM-MS) or gas chromatography-tandem mass spectrometry (GC-MS/MS) techniques. Among solvents tested to assess recovery of target compounds from 1-g tissue homogenates, acetone was selected as optimal for extracting compounds with dissimilar physicochemical properties from fish tissue. Initial experiments confirmed that GC-SIM-MS could be applied for analysis of lean fillet tissue (<1% lipid) without gel-permeation chromatography (GPC), and this approach was applied to assess the presence of target analytes in fish fillets collected from a regional effluent-dominated stream in Texas, USA. Benzophenone, galaxolide, tonalide, and triclosan were detected in 11 of 11 environmental samples at concentrations ranging from; 37 to 90, 234 to 970, 26 to 97, and 17 to 31 ng/g, respectively. However, performance of this analytical approach declined appreciably with increasing lipid content of analyzed tissues. Successful analysis of samples with increased lipid content was enabled by adding GPC to the sample preparation protocol and monitoring analytes with tandem mass spectrometry. Both analytical approaches were validated using fortified fillet tissue collected from locations expected to be minimally impacted by anthropogenic influences. Average analyte recoveries ranged from 87% to 114% with RSDs <11% and from 54% to 107% with RSDs <20% for fish tissue containing <1% and 4.9% lipid, respectively. Statistically derived method detection limits (MDLs) for GC-SIM-MS and GC-MS/MS methodologies ranged from 2.4 to 16 ng/g, and 5.1 to 397 ng/g, respectively.

    The objective of this study was to evaluate potential human and ecological risks associated with metals in fish and crayfish from mining in the Tri-States Mining District (TSMD). Crayfish (Orconectes spp.) and fish of six frequently consumed species (common carp, Cyprinus carpio; channel catfish, Ictalurus punctatus; flathead catfish, Pylodictis olivaris; largemouth bass, Micropterus salmoides; spotted bass, M. punctulatus; and white crappie, Pomoxis annularis) were collected in 2001-2002 from the Oklahoma waters of the Spring River (SR) and Neosho River (NR), which drain the TSMD. Samples from a mining-contaminated site in eastern Missouri and from reference sites were also analyzed. Individual fish were prepared for human consumption in the manner used locally by Native Americans (headed, eviscerated, and scaled) and analyzed for lead, cadmium, and zinc. Whole crayfish were analyzed as composite samples of 5-60 animals. Metals concentrations were typically higher in samples from sites most heavily affected by mining and lowest in reference samples. Within the TSMD, most metals concentrations were higher at sites on the SR than on the NR and were typically highest in common carp and crayfish than in other taxa. Higher concentrations and greater risk were associated with fish and crayfish from heavily contaminated SR tributaries than the SR or NR mainstems. Based on the results of this and previous studies, the human consumption of carp and crayfish could be restricted based on current criteria for lead, cadmium, and zinc, and the consumption of channel catfish could be restricted due to lead. Metals concentrations were uniformly low in Micropterus spp. and crappie and would not warrant restriction, however. Some risk to carnivorous avian wildlife from lead and zinc in TSMD fish and invertebrates was also indicated, as was risk to the fish themselves. Overall, the wildlife assessment is consistent with previously reported biological effects attributed to metals

Principal minerals by value included molybdenum concentrates, phosphate rock, sand and gravel, silver and portland cement. The state ranked second in phosphate and garnet production, third in silver and pumice, fourth in molybdenum concentrate production, and 21st overall. Majority of mining increases for the year were spurred by demand for metals by China's growing economy.

    Idaho Supplementation Studies (ISS) will help determine the utility of supplementation as a potential recovery tool for decimated stocks of spring and summer chinook salmon, Oncorhynchus tshawytscha, in Idaho as part of a program to protect, mitigate, and enhance fish and wildlife affected by the development and operation of hydroelectric power plants on the Columbia River. The objectives are to: (1) monitor and evaluate the effects of supplementation on presmolt and smolt numbers and spawning escapements of naturally produced salmon; (2) monitor and evaluate changes in natural productivity and genetic composition of target and adjacent populations following supplementation; and (3) determine which supplementation strategies provide the quickest and highest response in natural production without adverse effects on productivity. Field work began in 1991 with the collection of baseline data from treatment and some control streams. Full implementation began in 1992 with baseline data collection on treatment and control streams and releases of supplementation fish into several treatment streams. Field methods included snorkeling to estimate chinook salmon parr populations, PIT tagging summer parr to estimate parr-to-smolt survival, multiple redd counts to estimate spawning escapement and collect carcass information. Screw traps were used to trap and PIT tag outmigrating chinook salmon during the spring and fall outmigration. Weirs were used to trap and enumerate returning adult salmon in select drainages.

    This study proposed a strategy to identify and quantify 182 organic contaminants from different chemical classes, as for instance pesticides, veterinary drug and personal care products, in fish fillet using liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (LC-QToF/MS). For this purpose, two different scan methods (full scan and all ions MS/MS) were evaluated to assess the best option for screening analysis in spiked fish fillet samples. In general, full scan acquisition was found to be more reliable (84%) in the automatic identification and quantification when compared to all ions MS/MS with 72% of the compounds detected. Additionally, a qualitative automatic search showed a mass accuracy error below 5ppm for 77% of the compounds in full scan mode compared to only 52% in all ions MS/MS scan. However, all ions MS/MS provides fragmentation information of the target compounds. Undoubtedly, structural information of a wide number of compounds can be obtained using high resolution mass spectrometry (HRMS), but it is necessary thoroughly assess it, in order to choose the best scan mode.

    The reliability, reproducibility, and usefulness of three screening methods -- the cellophane transfer, the agar plug transfer, and the agar dilution -- to screen aquatic fungicides were evaluated. Achlya flagellata and Saprolegnia hypogyna were exposed to 1, 10, and 100 mg/L of malachite green to test each method. The cellophane transfer and agar plug transfer techniques had similar reliability and reproducibility in rating fungicidal activity, and were both superior to the agar dilution technique. The agar plug transfer and agar dilution techniques adequately projected in vivo activity of malachite green, but the cellophane transfer technique overestimated its activity. Overall, the agar plug transfer technique most accurately rated the activity of malachite green and was the easiest test to perform. It therefore appears to be the method of choice for testing aquatic fungicides.

    On the basis of mineral-resource surveys the Selkirk Roadless Area, Idaho has little promise for the occurrence of mineral or energy resources. Molybdenum, lead, uranium, thorium, chromium, tungsten, zirconium, and several rare-earth elements have been detected in panned concentrates from samples of stream sediment, but no minerals containing the first five elements were found in place, nor were any conditions conducive to their concentration found. Zirconium, thorium, and the rare earths occur in sparsely disseminated accessory minerals in granitic rocks and no resource potential is identified. There is no history of mining in the roadless area and there are no oil, gas, mineral, or geothermal leases or current claims.

    Project 83-7 was established under the Northwest Power Planning Council's 1982 Fish and Wildlife Program to monitor natural production of anadromous fish, evaluate Bonneville Power Administration (BPA) habitat improvement projects, and develop a credit record for off-site mitigation projects in Idaho. Project 83-7 is divided into two subprojects: general and intensive monitoring. Primary objectives of the general monitoring subproject (Part 1) are to determine natural production increases due to habitat improvement projects in terms of parr production and to determine natural production status and trends in Idaho. The second objective is accomplished by combining parr density data from monitoring and evaluation of BPA habitat projects and from other Idaho Department of Fish and Game (IDFG) management and research activities. Primary objectives of the intensive monitoring subproject (Part 2) are to determine the number of returning chinook and steelhead adults necessary to achieve optimal smolt production and to develop mitigation accounting based on increases in smolt production. Two locations are being intensively studied to meet these objectives. Field work began in 1987 in the upper Salmon River and Crooked River (South Fork Clearwater River tributary). 22 refs., 10 figs., 17 tabs.

    Direct solid sample analysis with graphite furnace atomic absorption spectrometry (SS-GF AAS) was investigated initially with the intention of developing a method for the determination of total As in fish and other seafood. A mixture of 0.1% Pd+0.06% Mg+0.06% Triton X-100 was used as the chemical modifier, added in solution over the solid samples, making possible the use of pyrolysis and atomization temperatures of 1200 °C and 2400 °C, respectively. The sample mass had to be limited to 0.25 mg, as the integrated absorbance did not increase further with increasing sample mass. Nevertheless, the recovery of As from several certified reference materials was of the order of 50% lower than the certified value. Strong molecular absorption due to the phosphorus monoxide molecule (PO) was observed with high-resolution continuum source AAS (HR CS AAS), which, however, did not cause any spectral interference. A microwave-assisted digestion with HNO3/H2O2 was also investigated to solve the problem; however, the results obtained for several certified reference materials were statistically not different from those found with direct SS-GF AAS. Accurate values were obtained using inductively coupled plasma mass spectrometry (ICP-MS) to analyze the digested samples, which suggested that organic As compounds are responsible for the low recoveries. HPLC-ICP-MS was used to determine the arsenobetaine (AB) concentration. Accurate results that were not different from the certified values were obtained when the AB concentration was added to the As concentration found by SS-GF AAS for most certified reference materials (CRM) and samples, suggesting that SS-GF AAS could be used as a fast screening procedure for inorganic As determination in fish and seafood.

    This is the first annual summary of results for chinook salmon supplementation studies in Idaho Rivers conducted by the Nez Perce Tribe Department of Fisheries Management. The Nez Perce Tribe has coordinated chinook salmon supplementation research activities with the Bonneville Power Administration, Idaho Department of Fish and Game, U. S. Fish and Wildlife Service, National Marine Fisheries Service, U. S. Forest Service, and the Shoshone Bannock Tribe. The project is a cooperative effort involving members of the Idaho Supplementation Technical Advisory Committee (ISTAC). This project has also been extensively coordinated with the Supplementation Technical Work Group (STWG) which identified specific research needs and integrated and coordinated supplementation research activities through development of a five year work plan. In this study we are assessing what strategies, both brood stock and release stage, are best for supplementing natural or depleted spring and summer chinook populations and what effect supplementation has on these populations. This research should identify which of the supplementation strategies employed are beneficial in terms of increasing adult returns and the ability of these returns to sustain themselves. Biological evaluation points will be parr density, survival to Lower Granite Dam, adult return to weirs, redd counts and presmolt and smolt yield from both treatment and control streams. Genetic monitoring of treatment and control populations will also occur. The supplementation research study has the following objectives: (1) Monitor and evaluate the effect of supplementation on presmolt and smolt numbers and spawning escapements of naturally produced salmon. (2) Monitor and evaluate changes in natural productivity and genetic composition of target and adjacent populations following supplementation. (3) Determine which supplementation strategies (brood stock and release stage) provide the quickest and highest response in natural

  18. Late Ordovician paleogeography of central Idaho and its tectonic implications

    Measures, E.A. )

    1991-02-01

    The Late Ordovician (Cincinnatian, Ashgill) paleogeography of central Idaho has been weakly constrained in the past. Previously, this area was treated as a simple extension of the miogeocline-eugeocline paleogeography defined from units in the Great Basin (Nevada and Utah). Detailed analysis of the Upper Ordovician Fish Haven Dolomite enables a more refined paleogeographic interpretation to be made at this time. The Fish Haven Dolomite (260 m or 800 ft, average thickness) of central Idaho is composed of 16 different carbonate facies which can be grouped into three sequences; facies within each sequence are depositionally related. Overall, the facies and sequences indicate that a carbonate ramp formed in central Idaho outboard of the craton and a hinge zone, within a subsiding area of the miogeocline. Shallow subtidal ramp deposits were probably deposited in approximately 30 m (100 ft.), or less, of water depth. During this time interval, open ocean, anoxic bottom waters extended up into deep ;subtidal regions (60 m or 200 ft). This information indicates that the Late Ordovician carbonate ramp underwent backstepping at its outermost portion resulting n drowning of the western ramp and eventual migration of transitional facies deposits (Roberts Mountains Formation) over miogeoclinal deposits. Tectonics played an active part in the deposition of the Fish Haven Dolomite in the miogeocline of central Idaho. The ultimate cause of the tectonism is not known at this time, but could be related to changes in the rate of sea-floor spreading, active structures within the continental margin, proximity of the Ordovician Klamath Mountains island arc Terrane, or unknown processes.

    Henrys Lake, located in southeastern Idaho, is a large, shallow lake (6,600 acres, {approx} 17.1 feet maximum depth) located at 6,472 feet elevation in Fremont Co., Idaho at the headwaters of the Henrys Fork of the Snake River. The upper watershed is comprised of high mountains of the Targhee National Forest and the lakeshore is surrounded by extensive flats and wetlands, which are mostly privately owned. The lake has been dammed since 1922, and the upper 12 feet of the lake waters are allocated for downriver use. Henrys Lake is a naturally productive lake supporting a nationally recognized ''Blue Ribbon'' trout fishery. There is concern that increasing housing development and cattle grazing may accelerate eutrophication and result in winter and early spring fish kills. There has not been a recent thorough assessment of lake water quality. However, the Department of Environmental Quality (DEQ) is currently conducting a study of water quality on Henrys Lake and tributary streams. Septic systems and lawn runoff from housing developments on the north, west, and southwest shores could potentially contribute to the nutrient enrichment of the lake. Many houses are on steep hillsides where runoff from lawns, driveways, etc. drain into wetland flats along the lake or directly into the lake. In addition, seepage from septic systems (drainfields) drain directly into the wetlands enter groundwater areas that seep into the lake. Cattle grazing along the lake margin, riparian areas, and uplands is likely accelerating erosion and nutrient enrichment. Also, cattle grazing along riparian areas likely adds to nutrient enrichment of the lake through subsurface flow and direct runoff. Stream bank and lakeshore erosion may also accelerate eutrophication by increasing the sedimentation of the lake. Approximately nine streams feed the lake (see map), but flows are often severely reduced or completely eliminated due to irrigation diversion. In addition, subsurface flows can occur as a

    The Sawtooth Wilderness in Idaho consists of the former Sawtooth Primitive Area and certain contiguous tracts of land. A survey of the mineral-resource potential of the entire area disclosed hydrothermally altered and mineralized rocks at several localities, some of which have been prospected to a limited extent but none of which have produced significant quantities of ore. Sediment samples from many of the streams that drain the wilderness contained anomalous quantities of metals. At some sample sites the source of the anomalous concentrations of metals may be related to known mineralized out-crops but the source at many of the sites is unknown. The significant geochemical data, the extent of altered and mineralized rocks, and the proximity to other productive mineral districts in similar geologic environs indicate that substantial parts of the wilderness have probable mineral-resource potential. A placer deposit, in the northern part of the wilderness, has substantiated potential for rare-earth elements; an area in the southern part of the wilderness has substantiated potential for precious metals; and several mines in the wilderness have demonstrated resources of base and precious metals. The geologic setting precludes the presence of fossil fuels.

    There are 899 thermal water occurrences known in Idaho, including 258 springs and 641 wells having temperatures ranging from 20 to 93/sup 0/C. Fifty-one cities or towns in Idaho containing 30% of the state's population are within 5 km of known geothermal springs or wells. These include several of Idaho's major cities such as Lewiston, Caldwell, Nampa, Boise, Twin Falls, Pocatello, and Idaho Falls. Fourteen sites appear to have subsurface temperatures of 140/sup 0/C or higher according to the several chemical geothermometers applied to thermal water discharges. These include Weiser, Big Creek, White Licks, Vulcan, Roystone, Bonneville, Crane Creek, Cove Creek, Indian Creek, and Deer Creek hot springs, and Raft River, Preston, and Magic Reservoir areas. These sites could be industrial sites, but several are in remote areas away from major transportation and, therefore, would probably be best utilized for electrical power generation using the binary cycle or Magma Max process. Present uses range from space heating to power generation. Six areas are known where commercial greenhouse operations are conducted for growing cut and potted flowers and vegetables. Space heating is substantial in only two places (Boise and Ketchum) although numerous individuals scattered throughout the state make use of thermal water for space heating and private swimming facilities. There are 22 operating resorts using thermal water and two commercial warm-water fish-rearing operations.

    The Idaho Department of Fish and Game (IDFG) has been monitoring trends in juvenile spring and summer chinook salmon, Oncorhynchus tshawytscha, and steelhead trout, O. mykiss, populations in the Salmon, Clearwater, and lower Snake River drainages for the past 12 years. This work is the result of a program to protect, mitigate, and enhance fish and wildlife affected by the development and operation of hydroelectric power plants on the Columbia River. Project 91-73, Idaho Natural Production Monitoring, consists of two subprojects: General Monitoring and Intensive Monitoring. This report updates and summarizes data through 1995 for the General Parr Monitoring (GPM) database to document status and trends of classes of wild and natural chinook salmon and steelhead trout populations. A total of 281 stream sections were sampled in 1995 to monitor trends in spring and summer chinook salmon Oncorhynchus tshawytscha and steelhead trout O. mykiss parr populations in Idaho. Percent carrying capacity and density estimates were summarized for 1985--1995 by different classes of fish: wild A-run steelhead trout, wild B-run steelhead trout, natural A-run steelhead trout, natural B-run steelhead trout, wild spring and summer chinook salmon, and natural spring and summer chinook salmon. The 1995 data were also summarized by subbasins as defined in Idaho Department of Fish and Game`s 1992--1996 Anadromous Fish Management Plan.

    An evaluation of existing and proposed habitat improvement projects for anadromous fish in the Clearwater River and Salmon River drainages was conducted. The Clearwater River and Salmon River drainages account for virtually all of Idaho's wild and natural production of summer steelhead and spring and summer chinook salmon, as well as a remnant run of sockeye salmon. Habitat enhancement projects are intended to either increase the amount of habitat, or increase the carrying capacity of existing (usually, degraded) habitat, or both. Migration barriers, such as waterfalls, culverts, and water diversions, can be modified to make available habitat that is not being used, or is underutilized, by anadromous fish. The objectives of this evaluation are: (1) document physical changes in habitat; (2) measure changes in steelhead and chinook production attributable to habitat enhancement projects; (3) measure changes in standing crops of resident fish species due to enhancement; and (4) determine project effectiveness, including relative costs and benefits, to establish the record of credit for mitigation and to guide future management actions. It was not possible to define the level of enhancement for any BPA project in 1984. Evaluations for all projects except three were in the pre-treatment phase during 1984. Because full benefits cannot be defined at current low seeding levels, projects must be monitored until full-seeding is approached. We obtained post-treatment information for three projects in 1984: Lolo Creek instream structures; upper Lochsa River instream structures; and screening of the irrigation diversion on Pole Creek. Of the three, only the Lolo Creek project exhibited any apparent benefits; these apparent benefits were not conclusively determined in 1984. The Lolo Creek project requires a follow-up evaluation in 1985. The Pole Creek project requires better passage for adult chinook at the irrigation diversion. 36 refs., 71 figs., 50 tabs. (ACR)

    This work was the result of a program to protect, mitigate, and enhance fish and wildlife affected by the development and operation of hydroelectric power plants on the Columbia River. Adult and jack chinook salmon escapement were indexed by redd counts and weir returns. Escapement in 1994 was low and in some cases approached the lowest on record. Although stream flow conditions and parr abundance were conducive to precise parr population estimates, some streams continued to exhibit wide confidence intervals. Different methods used to calculate the estimates yielded inconsistent results with regard to increasing or decreasing the population estimate and improving the precision of the estimates. No single method appeared definitively better for all streams. Emigrant traps captured 78,138 chinook salmon fry, parr, and smolts in 1994. Application of a weekly trap efficiency adjusted for stream flow produced emigration estimates that were up to 30% larger than when a seasonal trap efficiency was used. Detection rates for smolts tagged in some streams were similar to detection rates for parr tagged during the fall of the previous year. This was unexpected because overwinter mortality usually results in a lower detection rate for fall-tagged fish. Low escapement in 1994 severely hampered Idaho Supplementation Studies (ISS) broodstock development. The inability to develop local broodstocks for supplementation is the most important factor threatening the implementation of the ISS.

    Becoming a career fire fighter in the state of Idaho requires specialized knowledge and training. Fire science education at Idaho colleges and universities is available only to people who are affiliated with a fire department. Law enforcement curriculum, on the other hand, is available to any interested persons. A student in law enforcement can attend the Police Officers Standards and Training (POST) academy or participate in classes in one of Idaho's institutions for higher education. There are no fire academies in Idaho. Applicants wanting to become professional fire fighters in Idaho are required to compete with applicants from other states; many of whom have had prior fire education and training. Resident Idaho fire fighter applicants are at a disadvantage when applying for Idaho fire fighting positions. Because of this apparent need, I surveyed the Idaho fire chiefs, using a research instrument I developed in a graduate field research class. I wrote the research instrument to determine the educational needs of the Idaho fire service. The College of Southern Idaho (CSI) and the Idaho Fire Chiefs Association (IFCA) were the recipients of this survey. This report, Analysis of Idaho Fire Service Education, describes that research process from beginning to end.

    Screening and analysis of bioactive compounds from natural products is challenging work due to their complexity. This study presents the first report on hyphenation of solid-phase ligand-fishing using immobilized xanthine oxidase microcolumn (IXOM) and high-performance liquid chromatography-diode array detector-tandem mass spectrometry (HPLC-DAD-MS/MS) for screening and identification of XO inhibitors from complex mixtures. Solid-phase ligand-fishing system was hyphenated with the HPLC system via four-port switching valve and a six-port injection valve as an interface for transferring effluents from IXOM to HPLC, and collecting chromatograms from LFMC (ligand-fishing microextraction column) and C18 column in a run by only one DAD. Mixtures containing allopurinol (positive control) and tryptophane (negative control) were analyzed in order to verify the specificity and reproducibility of the approach. Subsequently, the newly developed system was applied to screening and identification of XO inhibitors from L. macranthoides and its human microsomal metabolites. Six prototype compounds (3-caffeoylquinic acid, 5-caffeoylquinic acid, 4-caffeoylquinic acid, 3,4-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid) and three metabolites (3-caffeoyl-epi-quinic acid, 5-caffeoyl-epi-quinic acid, 4-caffeoyl-epi-quinic acid) with XO binding affinities were identified. The XO inhibition activities of six prototype compounds were evaluated and confirmed using in vitro enzymatic assay. With the online system developed here, we present a feasible, selective, and effective strategy for rapid screening and identification of enzyme inhibitors from complex mixtures. PMID:27438719

    The geothermal resource of southern Idaho as assessed by the U.S. Geological Survey in 1978 is large. Most of the known hydrothermal systems in southern Idaho have calculated reservoir temperatures of less than 150?C. Water from many of these systems is valuable for direct heat applications, but is lower than the temperature of interest for commercial generation of electricity at the present time. Most of the known and inferred geothermal resources of southern Idaho underlie the Snake River Plain. However, major uncertainties exist concerning the geology and temperatures beneath the plain. By far the largest hydrothermal system in Idaho is in the Bruneau-Grand View area of the western Snake River Plain with a calculated reservoir temperature of 107?C and an energy of 4.5? 10 20 joules. No evidence of higher temperature water associated with this system has been found. Although the geology of the eastern Snake River Plain suggests that a large thermal anomaly may underlie this area of the plain, direct evidence of high temperatures has not been found. Large volumes of water at temperatures between 90? and 150?C probably exist along the margins of the Snake River Plain and in local areas north and south of the plain. Areas that appear particularly promising for the occurrence of large high-temperature hydrothermal systems are: the area north of the Snake River Plain and west of the Idaho batholith, the Island Park area, segments of the margins of the eastern Snake River Plain, and the Blackfoot lava field.

    In 2001, Idaho Department of Fish and Game (IDFG) continued an assessment of the Sawtooth Hatchery steelhead Oncorhynchus mykiss stock to reestablish natural populations in Beaver and Frenchman creeks in the upper Salmon River. Crews stocked both streams with 20 pair of hatchery adults, and I estimated the potential smolt production from the 2000 adult outplants. n the Red River drainage, IDFG stocked Dworshak hatchery stock fingerlings and smolts from 1993 to 1999 to assess which life stage produces more progeny when the adults return to spawn. In 2001, IDFG operated the Red River weir to trap adults that returned from these stockings, but none were caught from either group. Wild steelhead populations in the Lochsa and Selway river drainages were assessed and the chinook salmon Oncorhynchus tshawytscha escapement was enumerated in Fish Creek. I estimated that 75 wild adult steelhead and 122 adult chinook salmon returned to Fish Creek in 2001. I estimated that slightly more than 30,000 juvenile steelhead migrated out of Fish Creek. This is the largest number of steelhead to migrate out of Fish Creek in a single year since I began estimating the yearly migration in 1994. Juvenile steelhead densities in Lochsa and Selway tributaries were somewhat higher in 2001 than those observed in 2000. Crews from IDFG collected over 4,800 fin samples from wild steelhead in 74 streams of the Clearwater, Snake, and Salmon river drainages and from five hatchery stocks during the summer of 2000 for a DNA analysis to assess Idaho's steelhead stock structure. The DNA analysis was subcontracted to Dr. Jennifer Nielsen, Alaska Biological Science Center, Anchorage. Her lab developed protocols to use for the analysis in 2001 and is continuing to analyze the samples. Dr. Nielsen plans to have the complete set of wild and hatchery stocks analyzed in 2002.

    This report summarizes brood year 1999 juvenile production and emigration data and adult return information for 2000 for streams studied by the Nez Perce Tribe for the cooperative Idaho Salmon Supplementation Studies in Idaho Rivers (ISS) project. In order to provide inclusive juvenile data for brood year 1999, we include data on parr, presmolt, smolt and yearling captures. Therefore, our reporting period includes juvenile data collected from April 2000 through June 2001 for parr, presmolts, and smolts and through June 2002 for brood year 1999 yearling emigrants. Data presented in this report include; fish outplant data for treatment streams, snorkel and screw trap estimates of juvenile fish abundance, juvenile emigration profiles, juvenile survival estimates to Lower Granite Dam (LGJ), redd counts, and carcass data. There were no brood year 1999 treatments in Legendary Bear or Fishing Creek. As in previous years, snorkeling methods provided highly variable population estimates. Alternatively, rotary screw traps operated in Lake Creek and the Secesh River provided more precise estimates of juvenile abundance by life history type. Juvenile fish emigration in Lake Creek and the Secesh River peaked during July and August. Juveniles produced in this watershed emigrated primarily at age zero, and apparently reared in downstream habitats before detection as age one or older fish at the Snake and Columbia River dams. Over the course of the ISS study, PIT tag data suggest that smolts typically exhibit the highest relative survival to Lower Granite Dam (LGJ) compared to presmolts and parr, although we observed the opposite trend for brood year 1999 juvenile emigrants from the Secesh River. SURPH2 survival estimates for brood year 1999 Lake Creek parr, presmolt, and smolt PIT tag groups to (LGJ) were 27%, 39%, and 49% respectively, and 14%, 12%, and 5% for the Secesh River.

    Self-reporting bias in sport fisheries of Chinook Salmon Oncorhynchus tshawytscha in Idaho was quantified by comparing observed and angler-reported data. A total of 164 observed anglers fished for 541 h and caught 74 Chinook Salmon. Fifty-eight fish were harvested and 16 were released. Anglers reported fishing for 604 h, an overestimate of 63 h. Anglers reported catching 66 fish; four less harvested and four less released fish were reported than observed. A Monte Carlo simulation revealed that when angler-reported data were used, total catch was underestimated by 14–15 fish (19–20%) using the ratio-of-means estimator to calculate mean catch rate. Negative bias was reduced to six fish (8%) when the means-of-ratio estimator was used. Multiple linear regression models to predict reporting bias in time fished had poor predictive value. However, actual time fished and a categorical covariate indicating whether the angler fished continuously during their fishing trip were two variables that were present in all of the top a priori models evaluated. Underreporting of catch and overreporting of time fished by anglers present challenges when managing Chinook Salmon sport fisheries. However, confidence intervals were near target levels and using more liberal definitions of angling when estimating effort in creel surveys may decrease sensitivity to bias in angler-reported data.

    The U.S. Geological Survey has used 23 different shotpoints during two seasons of field work in our seismic study of crustal structure in western United States. Without exception, it has been found that under-water shotpoints result in a more efficient conversion of explosive energy into seismic energy than do drilled-hole shotpoints. This experience, together with elimination of drilling costs, has led to the use of underwater shotpoints wherever possible. Three of the 23 shotpoints were in the Pacific Ocean, and for these we have no detailed information on the fish kill. Another six shotpoints were located in inland bodies of water. These are: * Soda Lake near Fallon, Nevada * Mono Lake near Lee Vining, California * Lake Mead near Boulder City, Nevada * Shasta Lake near Redding, California * C.J. Strike Reservoir near Bruneau, Idaho * Lucky Peak Reservoir near Boise, Idaho The 22 high-explosive charges, weighing a total of 95,100 pounds, that were fired in lakes containing fish life resulted in the known death of 2,413 game fish with a total weight of 759 pounds. The average mortality was 110 game fish or 34.5 pounds of game fish killed per average shot of 4,325 pounds of high-explosives.

    A modified tier 1 Endocrine Disruptor Screening Program (EDSP) 21-d fish short-term reproduction assay (FSTRA) was used to evaluate the effects of sediment exposure from freshwater and brackish ponds in Bermuda on reproductive fecundity and endocrine function in fathead minnow (Pimephales promelas) and killifish (Fundulus heteroclitus). Reproductively active male and female fish were exposed to control sediment and sediment from 2 freshwater ponds (fathead minnow) and 2 marine ponds (killifish) contaminated with polyaromatic hydrocarbons and metals via flow-through exposure for 21 d. Reproductive fecundity was monitored daily. At termination, the status of the reproductive endocrine system was assessed by the gonadosomatic index, gonadal histology, plasma steroids (estrogen [E2], testosterone [T], and 11-ketotestosterone [11-KT]), steroidogenic enzymes (aromatase and combined 3β/17β -hydroxysteroid dehydrogenase [3β/17β-HSD]), and plasma vitellogenin (VTG). Decreased reproductive fecundity, lower male body weight, and altered endocrinological measures of reproductive status were observed in both species. Higher plasma T levels in female minnows and 11-KT levels in both male and female minnows and female killifish exposed to freshwater and brackish sediments, respectively. Decreased female E2 and VTG levels and gonadal cytochrome P19 (aromatase) activity were also found in sediment exposed females from both species. No effect on female 3β/17β-HSD activity was found in either species. The FSTRA provided a robust model capable of modification to evaluate reproductive effects of sediment exposure in fish.

    Duke, Rodney C.

    1986-03-01

    All Idaho hatchery-reared steelhead released in the spring of 1985 received an adipose fin clip to differentiate between natural or wild and hatchery, fish, thus allowing for protection of wild fish in the sport harvest. Between 25 September and 14 December 1984, 6,360,542 steelhead trout (Salmo gairdneri) were marked by excising the adipose fin. A total of 10,336 man hours were required to complete the operation. Clip quality and healing, mortality, and adipose fin composition were determined. Quality checks indicated less than 1% of the fish had more than 25% of the fin remaining. Combined mortality at all three hatcheries was 0.3% of the total fish marked. Observed and in vivo test showed complete healing of the excision within 3-4 weeks (observed) and 22 days (in vivo). Bibliographies were compiled for fin regeneration, marked fish survival, hooking mortality, and related catch-and-release studies.

    To figure out the key phenolic compounds accounting for the antioxidant effects of longan (Dimocarpus longan Lour.) seed extract, online fishing/knockout method, activity evaluation assays, Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS), and high-performance liquid chromatography electrospray ionization mass spectrometry (HPLC-ESI-MS) analysis were used jointly for the first time. p-Coumaric acid-glycoside, (S)-flavogallonic acid, ellagic acid derivative, and methyl-ellagic acid glucopyranoside were first identified in longan seeds. In addition, our study revealed that ellagic acid as well as its derivative and p-coumaric acid-glycoside had important contribution to the potent antioxidant activity of longan seed extract, while gallic acid, corilagin, (S)-flavogallonic acid, methyl-ellagic acid glucopyranoside, and ethyl gallate showed very little contribution to the total antioxidant activity of longan seed extract. The combining use of the online fishing/knockout method, activity evaluation assays, FT-ICR-MS, and HPLC-ESI-MS analysis is a useful and simple strategy for screening of key bioactive compounds from complex extracts.

    A draft environmental impact statement (EPA No. 820563D) describes the estimated effects of a proposed hydroelectric project on the Snake River in Idaho which would include a 4300 by 40 foot earthen dam, with dikes on either side, a power canal, powerhouse, and a 3.76-mile transmission line and facilities. Power generated at the site would serve Idaho Falls, which expects to double in population over the next 15 years. Local workers would fill the 250 construction jobs. The reservoir would diversify the area's recreational potential. Negative impacts would be the loss of 24,000 feet of the Snake River and associated aquatic habitat, which would affect fish populations. The higher water level would restrict larger boats to the upper reservoir. Inundation of two small dams would create some hazards to boaters and eliminate their power generating capacity. Legal mandates for the study were the DOE Organization Act of 1977, Federal Power Act, Federal Water Pollution Control Act of 1972, and National Historic Preservation Act of 1966.

    1998-01-01

    The Salmon National Forest administers 1,776,994 net acres of mountainous terrain located in east-central Idaho. Most of the Forest is in Lemhi County; only a small portion falls within Idaho and Valley Counties. Approximately 426,114 acres of the Frank Church-River of No Return Wilderness extends into the western part of the Forest and mineral entry is severely restricted. Because of its location within the Salmon River drainage, the Forest also is subject to numerous issues surrounding restoration of anadromous fish runs. Mineral production from the Salmon National Forest began during 1866 when placer gold was discovered in Leesburg Basin. Hardrock mining quickly spread throughout the Forest and many deposits containing a wide range of commodities were discovered and developed. Although early records are sketchy, production is estimated to include 940,000 ounces gold, 654,000 ounces silver, 61.9 million pounds copper, 8.9 million pounds lead, 13.9 million pounds cobalt, 208,000 pounds zinc, and 37,000 tons fluorite mill feed. Mineral resources are large, diverse, and occur in many deposit types including exhalative, stockwork, disseminated, vein, replacement, sedimentary, skarn, breccia pipe, porphyry, and placer. The largest cobalt resource in the United States occurs in the Blackbird Mining District. Other resources include gold, silver, copper, lead, molybdenum, phosphate, manganese, iron, fluorite, uranium, thorium, rare earth oxides, and barite.

    Ground water pumping tests were performed in two wells located in the foothills east of Idaho Falls to determine the aquifer characteristics at these locations. These data were used to differentiate this aquifer from the Snake River Plain aquifer. The wells were pumped at rates of 11 and 14 gallons per minute with 0.03 and 0.04 ft of drawdown measured in the pumping wells. The transmissivity is estimated to be 525,000 gpd/ft and 450,000 gpd/ft, respectively. The hydraulic conductivity is 925 ft/day and 1,070 ft/day, respectively. These hydraulic conductivities are similar to those measured in the Snake River Plain aquifer. Water level data in these wells are consistent with the water table in the Snake River Plain aquifer and indicates ground water movement from the foothills toward the Plain. The high transmissivity suggests water may move rapidly from the foothills area to mix with water in the Snake River Plain aquifer. Elevated water temperatures (76 and 70{degrees}F) and high specific conductivities in these wells indicate the presence of a foothills aquifer with characteristics that can be used to separate the two aquifer systems.

    1986-04-01

    Evaluation approaches to document a record of credit for mitigation were developed in 1984-1985 for most of the habitat projects. Restoration of upriver anadromous fish runs through increased passage survival at main stem Columbia and Snake River dams is essential to the establishment of an off-site mitigation record, as well as to the success of the entire Fish and Wildlife program. The mitigation record is being developed to use increased smolt production (i.e., yield) at full-seeding as the basic measure of benefit from a habitat project. The IDFG evaluation approach consists of three basic, integrated levels: general monitoring, standing crop evaluations, and intensive studies. Annual general monitoring of anadromous fish densities in a small number of sections for each project will be used to follow population trends and define full-seeding levels. For most projects, smolt production will be estimated indirectly from standing crop estimates by factoring appropriate survival rates from parr to smolt stages. Intensive studies in a few key production streams will be initiated to determine these appropriate survival rates and provide other basic biological information that is needed for evaluation of the Fish and Wildlife program. A common physical habitat and fish population data base is being developed for every BPA habitat project in Idaho to be integrated at each level of evaluation. Compatibility of data is also needed between Idaho and other agencies and tribes in the Columbia River basin. No final determination of mitigation credit for any Idaho habitat enhancement project has been attainable to date.

    All geologic conditions in the Dillon quadrangle (Montana and Idaho) have been thoroughly examined, and, using National Uranium Resource Evaluation criteria, environments are favorable for uranium deposits along fractured zones of Precambrian Y metasediments, in the McGowan Creek Formation, and in some Tertiary sedimentary basins. A 9-m-wide quartz-bearing fractured zone in Precambrian Y quartzites near Gibbonsville contains 175 ppM uranium, probably derived from formerly overlying Challis Volcanics by supergene processes. The Mississippian McGowan Creek Formation consists of uraniferous, black, siliceous mudstone and chert. In the Melrose district it has been fractured by a low-angle fault, and uranium has been further concentrated by circulating ground water in the 2- to 6-m-thick brecciated zones that in outcrop contain 90 to 170 ppM uranium. The Wise River, northern Divide Creek, Jefferson River, Salmon River, Horse Prairie, Beaverhead River, and upper Ruby River Basins are considered favorable for uranium deposits in sandstone. Present are suitable uraniferous source rocks such as the Boulder batholith, rhyolitic flow breccia, laharic deposits, or strongly welded tuffs; permeable sediments, including most sandstones and conglomerates, providing they do not contain devitrified glass; suitable reductants such as lignite, pyrite, or low-Eh geothermal water; and uranium occurrences.

    The Idaho Department of Fish and Game (IDFG) has been monitoring and evaluating existing and proposed habitat improvement projects for steelhead and chinook in the Clearwater and Salmon subbasins since 1984. Projects included in the monitoring are funded by, or proposed for funding by, the Bonneville Power Administration (BPA) under the Northwest Power Planning Act as off-site mitigation for downstream hydropower development on the Snake and Columbia Rivers. This monitoring project is also funded under the same authority. A mitigation record is being developed to use actual and potential increases in smolt production as the best measures of benefit from a habitat improvement project. This project is divided into two subprojects: general and intensive monitoring. Primary objectives of the general monitoring subproject are to determine natural production increases due to habitat improvement projects in terms of parr production and to determine natural production status and trends in Idaho. The second objective is accomplished by combining parr density from monitoring and evaluation of BPA habitat projects and from other IDFG management and research activities. The primary objective of the intensive monitoring subproject is to determine the relationships between spawning escapement, parr production, and smolt production in two Idaho streams; the upper Salmon River and Crooked River. Results of the intensive monitoring will be used to estimate mitigation benefits in terms of smolt production and to interpret natural production monitoring in Idaho. 30 refs., 19 figs., 34 tabs.

This evaluation project is also funded under the same authority (Fish and Wildlife Program, Northwest Power Planning Council). A mitigation record is being developed using increased carrying capacity and/or survival as the best measure of benefit from a habitat enhancement project. Determination of full benefit from a project depends on completion or maturation of the project and presence of adequate numbers of fish to document actual increases in fish production. The depressed status of upriver anadromous stocks has precluded measuring full benefits of any habitat project in Idaho. Partial benefit is credited to the mitigation record in the interim period of run restoration.

    Effective management of wild anadromous fisheries is partly dependent on defining relationships between escapement and production. These productivity relationships (or reproduction curves) depend on the nature of density-dependent mechanisms that control the population. Inherent is developing any relationship is specifying the fish population of interest and what is meant by escapement and production by that population. This report is a summary of sampling programs at all existing and proposed anadromous fish weirs in Idaho as of fall 1992. Only permanent or semi-permanent structures where long-term data could be collected are included. The summary is stratified by class of fish and by cell or drainage using the same classifications as the Idaho Anadromous Fish Management Plan. Included in the summary are escapement objectives above the existing and proposed weirs. Recommendations based on this summary were developed to provide coverage for all classes and most major drainages, yet minimize cost and duplication of efforts. this was a usefull approach as some chinook salmon weirs were identified that could be modified to monitor steelhead trout.

    A multi-class, multi-residue analytical method based on LC-MS/MS detection was developed for the screening and confirmation of 28 veterinary drug and metabolite residues in flatfish, shrimp and eel. The chosen veterinary drugs are prohibited or unauthorised compounds in Korea, which were categorised into various chemical classes including nitroimidazoles, benzimidazoles, sulfones, quinolones, macrolides, phenothiazines, pyrethroids and others. To achieve fast and simultaneous extraction of various analytes, a simple and generic liquid extraction procedure using EDTA-ammonium acetate buffer and acetonitrile, without further clean-up steps, was applied to sample preparation. The final extracts were analysed by ultra-high-performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS). The method was validated for each compound in each matrix at three different concentrations (5, 10 and 20 ng g(-1)) in accordance with Codex guidelines (CAC/GL 71-2009). For most compounds, the recoveries were in the range of 60-110%, and precision, expressed as the relative standard deviation (RSD), was in the range of 5-15%. The detection capabilities (CCβs) were below or equal to 5 ng g(-1), which indicates that the developed method is sufficient to detect illegal fishery products containing the target compounds above the residue limit (10 ng g(-1)) of the new regulatory system (Positive List System - PLS).

    1982-04-01

    The magnetotelluric (MT) method was used as one of several geophysical tools to study part of the Idaho Engineering Laboratory (INEL) facility. The purpose of the geophysical study on INEL was to investigate the facility for a possible site to drill a geothermal exploration well. A successful geothermal well would be used to provide hot water for a chemical processing plant. The MT method was employed to map any large-scale structures or conductivity anomalies that might prove interesting as geothermal exploration targets. In addition to the MT data, direct current resistivity soundings, gravity data, aeromagnetic data, and seismic refraction data were obtained in the course of the geophysical study. In the MT survey described in this paper, an additional goal was to provide a better understanding of the electrical units mapped in the regional study of the Snake River Plain (SNRP) by Stanley et al. (1977). It was thought that a widespread conductive layer found beneath surface basalts in the 1977 study could be categorized petrologically by a deep well and additional MT soundings done nearby. Also, INEL is located on the margin of the SNRP, and it was desired to have MT data in the area to study the electrical nature of the margin of the plain. The MT sounding interpretations did not indicate any conductivity anomalies or significant structures near the chemical processing plant which could be used to guide the location of the proposed geothermal well to be drilled to a depth of 3 km. The initial interpretation of the MT sounding data was done with one-dimensional models consisting of four or five layers, the minimum number required to fit the data. After the test well (INEL-1) was completed, the electric log was used to guide an improved one-dimensional ID interpretation of the MT sounding data. Profile models derived from the well log provided good agreement with velocity models derived from refraction seismic data. A resolution study using generalized inverse

    The Idaho Department of Fish and Game has been monitoring and evaluating existing and proposed habitat improvement projects for steelhead (Salmo gairdneri) and chinook salmon (Oncorhynchus tshawytscha) in the Clearwater and Salmon River drainages over the last four years. Projects included in the evaluation are funded by, or proposed for funding by, the Bonneville Power Administration (BPA) under the Northwest Power Planning Act as off-site mitigation for downstream hydropower development on the Snake and Columbia rivers. A mitigation record is being developed to use increased smolt production at full seeding as the best measure of benefit from a habitat enhancement project. Determination of full benefit from a project depends on presence of adequate numbers of fish to document actual increases in fish production. The depressed nature of upriver anadromous stocks have precluded attainment of full benefit of any habitat project in Idaho. Partial benefit will be credited to the mitigation record in the interim period of run restoration. According to the BPA Work Plan, project implementors have the primary responsibility for measuring physical habitat and estimating habitat change. To date, Idaho habitat projects have been implemented primarily by the US Forest Service (USFS). The Shoshone-Bannock Tribes (SBT) have sponsored three projects (Bear Valley Mine, Yankee Fork, and the proposed East Fork Salmon River projects). IDFG implemented two barrier-removal projects (Johnson Creek and Boulder Creek) that the USFS was unable to sponsor at that time. The role of IDFG in physical habitat monitoring is primarily to link habitat quality and habitat change to changes in actual, or potential, fish production. Individual papers were processed separately for the data base.

    As a federal agency, the U.S. Department of Energy has been directed by Congress, the U.S. president, and the American public to provide leadership in the preservation of prehistoric, historic, and other cultural resources on the lands it administers. This mandate to preserve cultural resources in a spirit of stewardship for the future is outlined in various federal preservation laws, regulations, and guidelines such as the National Historic Preservation Act, the Archaeological Resources Protection Act, and the National Environmental Policy Act. The purpose of this Cultural Resource Management Plan is to describe how the Department of Energy, Idaho Operations Office will meet these responsibilities at Idaho National Laboratory in southeastern Idaho. The Idaho National Laboratory is home to a wide variety of important cultural resources representing at least 13,500 years of human occupation in the southeastern Idaho area. These resources are nonrenewable, bear valuable physical and intangible legacies, and yield important information about the past, present, and perhaps the future. There are special challenges associated with balancing the preservation of these sites with the management and ongoing operation of an active scientific laboratory. The Department of Energy, Idaho Operations Office is committed to a cultural resource management program that accepts these challenges in a manner reflecting both the spirit and intent of the legislative mandates. This document is designed for multiple uses and is intended to be flexible and responsive to future changes in law or mission. Document flexibility and responsiveness will be assured through regular reviews and as-needed updates. Document content includes summaries of Laboratory cultural resource philosophy and overall Department of Energy policy; brief contextual overviews of Laboratory missions, environment, and cultural history; and an overview of cultural resource management practices.

    2009-05-07

    Pacific lamprey Lampetra tridentata have received little attention in fishery science until recently, even though abundance has declined significantly along with other anadromous fish species in Idaho. Pacific lamprey in Idaho have to navigate over eight lower Snake River and Columbia River hydroelectric facilities for migration downstream as juveniles to the Pacific Ocean and again as adults migrating upstream to their freshwater spawning grounds in Idaho. The number of adult Pacific lamprey annually entering the Snake River basin at Ice Harbor Dam has declined from an average of over 18,000 during 1962-1969 to fewer than 600 during 1998-2006. Based on potential accessible streams and adult escapement over Lower Granite Dam on the lower Snake River, we estimate that no more than 200 Pacific lamprey adult spawners annually utilize the Clearwater River drainage in Idaho for spawning. We utilized electrofishing in 2000-2006 to capture, enumerate, and obtain biological information regarding rearing Pacific lamprey ammocoetes and macropthalmia to determine the distribution and status of the species in the Clearwater River drainage, Idaho. Present distribution in the Clearwater River drainage is limited to the lower sections of the Lochsa and Selway rivers, the Middle Fork Clearwater River, the mainstem Clearwater River, the South Fork Clearwater River, and the lower 7.5 km of the Red River. In 2006, younger age classes were absent from the Red River.

    Mineral-resource studies of the Selway-Bitterroot Wilderness in Idaho County, Idaho, and Missoula and Ravalli Counties, Montana, were carried out. Four areas with probable and one small area of substantiated mineral-resource potential were recognized. The areas of the Running Creek, Painted Rocks, and Whistling Pig plutons of Tertiary age have probable resource potential for molybdenum, although detailed geochemical sampling and surface investigations failed to recognize mineralized systems at the surface. Randomly distributed breccia zones along a fault in the vicinity of the Cliff mine have a substantiated potential for small silver-copper-lead resources.

    1999-08-01

    In 1991, the Idaho Supplementation Studies (ISS) project was implemented to address critical uncertainties associated with hatchery supplementation of chinook salmon Oncorhynchus tshawytscha populations in Idaho. The project was designed to address questions identified in the Supplementation Technical Work Group (STWG) Five-Year-Workplan (STWG 1988). Two goals of the project were identified: (1) assess the use of hatchery chinook salmon to increase natural populations in the Salmon and Clearwater river drainages, and (2) evaluate the genetic and ecological impacts of hatchery chinook salmon on naturally reproducing chinook salmon populations. Four objectives to achieve these goals were developed: (1) monitor and evaluate the effects of supplementation on presmolt and smolt numbers and spawning escapements of naturally produced fish; (2) monitor and evaluate changes in natural productivity and genetic composition of target and adjacent populations following supplementation; (3) determine which supplementation strategies (broodstock and release stage) provide the quickest and highest response in natural production without adverse effects on productivity; and (4) develop supplementation recommendations. This document reports on the first five years of the long-term portion of the ISS project. Small-scale studies addressing specific hypotheses of the mechanisms of supplementation effects (e.g., competition, dispersal, and behavior) have been completed. Baseline genetic data have also been collected. Because supplementation broodstock development was to occur during the first five years, little evaluation of supplementation is currently possible. Most supplementation adults did not start to return to study streams until 1997. The objectives of this report are to: (1) present baseline data on production and productivity indicators such as adult escapement, redd counts, parr densities, juvenile emigrant estimates, and juvenile survival to Lower Granite Dam (lower Snake

    In 2000, we continued our assessment of the Sawtooth Hatchery steelhead stock to reestablish natural populations in Beaver and Frenchman creeks in the upper Salmon River. We stocked both streams with 15 pair of hatchery adults and estimated the potential smolt production from the 1999 outplant. I estimated that about nine smolts per female could be produced in both streams from the 1999 outplant. The smolt-to-adult return would need to exceed 20% to return two adults at this level of production. In the Red River drainage, we stocked Dworshak hatchery stock fingerlings and smolts, from 1993 to 1999, to assess which life-stage produces more progeny when the adults return to spawn. In 2000, we operated the Red River weir to trap adults that returned from these stockings, but none were caught from either group. We continued to monitor wild steelhead populations in the Lochsa and Selway river drainages. We estimated that 26 wild adult steelhead returned to Fish Creek. This is the lowest adult escapement we have documented (when the weir was intact all spring) since we began monitoring Fish Creek in 1992. I estimated that nearly 25,000 juvenile steelhead migrated out of Fish Creek this year. Juvenile steelhead densities in Lochsa and Selway tributaries were similar to those observed in 1999. In 2000, we obtained funding for a DNA analysis to assess Idaho's steelhead stock structure. We collected fin samples from wild steelhead in 70 streams of the Clearwater, Snake, and Salmon River drainages and from our five hatchery stocks. The DNA analysis was subcontracted to Dr. Jennifer Nielsen, Alaska Biological Science Center, Anchorage, and will be completed in 2001.

    In 2009, the U.S. Geological Survey in cooperation with the U.S. Department of Energy's Naval Reactors Laboratory Field Office, Idaho Branch Office cored and completed well NRF-16 for monitoring the eastern Snake River Plain (SRP) aquifer. The borehole was initially cored to a depth of 425 feet below land surface and water samples and geophysical data were collected and analyzed to determine if well NRF-16 would meet criteria requested by Naval Reactors Facility (NRF) for a new upgradient well. Final construction continued after initial water samples and geophysical data indicated that NRF-16 would produce chemical concentrations representative of upgradient aquifer water not influenced by NRF facility disposal, and that the well was capable of producing sustainable discharge for ongoing monitoring. The borehole was reamed and constructed as a Comprehensive Environmental Response Compensation and Liability Act monitoring well complete with screen and dedicated pump. Geophysical and borehole video logs were collected after coring and final completion of the monitoring well. Geophysical logs were examined in conjunction with the borehole core to identify primary flow paths for groundwater, which are believed to occur in the intervals of fractured and vesicular basalt and to describe borehole lithology in detail. Geophysical data also were examined to look for evidence of perched water and the extent of the annular seal after cement grouting the casing in place. Borehole videos were collected to confirm that no perched water was present and to examine the borehole before and after setting the screen in well NRF-16. Two consecutive single-well aquifer tests to define hydraulic characteristics for well NRF-16 were conducted in the eastern SRP aquifer. Transmissivity and hydraulic conductivity averaged from the aquifer tests were 4.8 x 103 ft2/d and 9.9 ft/d, respectively. The transmissivity for well NRF-16 was within the range of values determined from past aquifer

    2012-01-01

    In 2011, the U.S. Geological Survey, in cooperation with the U.S. Department of Energy, cored and completed borehole USGS 136 for stratigraphic framework analyses and long-term groundwater monitoring of the eastern Snake River Plain aquifer at the Idaho National Laboratory. The borehole was initially cored to a depth of 1,048 feet (ft) below land surface (BLS) to collect core, open-borehole water samples, and geophysical data. After these data were collected, borehole USGS 136 was cemented and backfilled between 560 and 1,048 ft BLS. The final construction of borehole USGS 136 required that the borehole be reamed to allow for installation of 6-inch (in.) diameter carbon-steel casing and 5-in. diameter stainless-steel screen; the screened monitoring interval was completed between 500 and 551 ft BLS. A dedicated pump and water-level access line were placed to allow for aquifer testing, for collecting periodic water samples, and for measuring water levels. Geophysical and borehole video logs were collected after coring and after the completion of the monitor well. Geophysical logs were examined in conjunction with the borehole core to describe borehole lithology and to identify primary flow paths for groundwater, which occur in intervals of fractured and vesicular basalt. A single-well aquifer test was used to define hydraulic characteristics for borehole USGS 136 in the eastern Snake River Plain aquifer. Specific-capacity, transmissivity, and hydraulic conductivity from the aquifer test were at least 975 gallons per minute per foot, 1.4 × 105 feet squared per day (ft2/d), and 254 feet per day, respectively. The amount of measureable drawdown during the aquifer test was about 0.02 ft. The transmissivity for borehole USGS 136 was in the range of values determined from previous aquifer tests conducted in other wells near the Advanced Test Reactor Complex: 9.5 × 103 to 1.9 × 105 ft2/d. Water samples were analyzed for cations, anions, metals, nutrients, total organic

    This report presents chemical compositions determined from 84 subsamples and 5 quality-assurance split subsamples of basalt core from the eastern Snake River Plain. The 84 subsamples were collected at selected depths from 5 coreholes located on the Idaho National Engineering Laboratory, Idaho. This report was jointly prepared by Lockheed Idaho Technologies Company and the U.S. Geological Survey, in cooperation with the U.S. Department of Energy, Idaho Operations Office. Ten major elements and as many as 32 trace elements were determined for each subsample either by wavelength dispersive X-ray fluorescence spectrometry, inductively coupled plasma mass spectrometry, or by both methods. Descriptive statistics for each element were calculated and tabulated by analytical method for each corehole.

  5. Cowlitz Falls Fish Passage.

    SciTech Connect

    1995-09-01

    The upper Cowlitz was once home to native salmon and steelhead. But the combined impacts of overharvest, farming, logging and road building hammered fish runs. And in the 1960s, a pair of hydroelectric dams blocked the migration path of ocean-returning and ocean-going fish. The lower Cowlitz still supports hatchery runs of chinook, coho and steelhead. But some 200 river miles in the upper river basin--much of it prime spawning and rearing habitat--have been virtually cut off from the ocean for over 26 years. Now the idea is to trap-and-haul salmon and steelhead both ways and bypass previously impassable obstacles in the path of anadromous fish. The plan can be summarized, for the sake of explanation, in three steps: (1) trap and haul adult fish--collect ocean-returning adult fish at the lowermost Cowlitz dam, and truck them upstream; (2) reseed--release the ripe adults above the uppermost dam, and let them spawn naturally, at the same time, supplement these runs with hatchery born fry that are reared and imprinted in ponds and net pens in the watershed; (3) trap and haul smolts--collection the new generation of young fish as they arrive at the uppermost Cowlitz dam, truck them past the three dams, and release them to continue their downstream migration to the sea. The critical part of any fish-collection system is the method of fish attraction. Scientists have to find the best combination of attraction system and screens that will guide young fish to the right spot, away from the turbine intakes. In the spring of 1994 a test was made of a prototype system of baffles and slots on the upriver face of the Cowlitz Falls Dam. The prototype worked at 90% efficiency in early tests, and it worked without the kind of expensive screening devices that have been installed on other dams. Now that the success of the attraction system has been verified, Harza engineers and consultants will design and build the appropriate collection part of the system.

    1994-02-01

    The Idaho Department of Fish and Game (IDFG) has been monitoring and evaluating proposed and existing habitat improvement projects for rainbow-steelhead trout Oncorhynchus mykiss and chinook salmon O. tshawytscha in the Clearwater River and Salmon River drainages on a large scale for the past 8 years. Projects included in the evaluation are funded by, or proposed for funding by, the Bonneville Power Administration (BPA) under the Northwest Power Planning Act as off-site mitigation for downstream hydropower development on the Snake and Columbia rivers. A mitigation record is being developed using increased carrying capacity and/or survival as the best measures of benefit from a habitat enhancement project. Determination of full benefit from a project depends on completion or maturation of the project and presence of adequate numbers of fish to document actual increases in fish production. The depressed status of upriver anadromous stocks has precluded measuring full benefits of any habitat project in Idaho. Partial benefit is credited to the mitigation record in the interim period of run restoration.

    A beam emittance measurement of the 16 MeV S-band High Repetition Rate Linac (HRRL) was performed at Idaho State University's Idaho Accelerator Center (IAC). The HRRL linac structure was upgraded beyond the capabilities of a typical medical linac so it can achieve a repetition rate of 1 kHz. Measurements of the HRRL transverse beam emittance are underway that will be used to optimize the production of positrons using HRRL's intense electron beam on a tungsten converter. In this paper, we describe a beam imaging system using on an OTR screen and a digital CCD camera, a MATLAB tool to extract beamsize and emittance, detailed measurement procedures, and the measured transverse emittances for an arbitrary beam energy of 15 MeV.

    Kurath, G.; Winton, J.

    2008-01-01

    Many important viral pathogens of fish are members of the family Rhabdoviridae. The viruses in this large group cause significant losses in populations of wild fish as well as among fish reared in aquaculture. Fish rhabdoviruses often have a wide host and geographic range, and infect aquatic animals in both freshwater and seawater. The fish rhabdoviruses comprise a diverse collection of isolates that can be placed in one of two quite different groups: isolates that are members of the established genusNovirhabdovirus, and those that are most similar to members of the genus Vesiculovirus. Because the diseases caused by fish rhabdoviruses are important to aquaculture, diagnostic methods for their detection and identification are well established. In addition to regulations designed to reduce the spread of fish viruses, a significant body of research has addressed methods for the control or prevention of diseases caused by fish rhabdoviruses, including vaccination. The number of reported fish rhabdoviruses continues to grow as a result of the expansion of aquaculture, the increase in global trade, the development of improved diagnostic methods, and heightened surveillance activities. Fish rhabdoviruses serve as useful components of model systems to study vertebrate virus disease, epidemiology, and immunology.

  1. Fish flavor.

    PubMed

    Kawai, T

    1996-02-01

    This article reviews features of flavor in three groups of fishes and summarizes them as follows: (1) fresh saltwater fish are nearly odorless because they contain a small quantity of volatiles; (2 freshwater fish give off pyrrolidine and earthy-odor compounds, which are responsible for their maturity and surrounding water pollution, and (3) euryhaline fish exhibit a variety of unsaturated carbonyls and alcohols derived from enzymatic and nonenzymatic oxidation of polyunsaturated fatty acids (PAs). These features are discussed, as are the effects of different enzymatic activities on PA oxidation and the effects of pH on mechanisms of formation of the volatiles. The monotonous volatile constitution of saltwater fish is likely caused by an unknown antioxidation system restraining the fish from oxidizing. The variety of constitution of euryhaline fish, especially that of anadromous fish under spawning conditions, could result from the loss of that system. The thermal environments of heated foods are also reviewed. The basic environment of fish, which allows the formation of flavor compounds, is discussed to confirm the volatiles found in unheated fish.

  4. Lu-Hf garnet geochronology of the Salmon River Suture Zone, West-Central Idaho

    Wilford, D. E.; Vervoort, J. D.; Lewis, R.; Tikoff, B.

    2011-12-01

    The Salmon River Suture Zone (SRSZ) in west-central Idaho records the accretion of island arc terranes to North America. It is modified by the Western Idaho Shear Zone (WISZ), a high strain zone within the SRSZ, which defines the present-day boundary between old continental North America and the accreted oceanic assemblages. Timing of the onset of deformation on the WISZ is not well established, primarily due to a poorly constrained metamorphic history. Existing garnet geochronologic studies of units within the SRSZ, using the Sm-Nd isotope system, have provided a framework towards a progressive accretion of arc-derived rocks to North America [1,2]. In this study, we report on the application of the Lu-Hf isotope system to provide ages of garnet growth within the suture zone. This system has the advantage of being insensitive to light rare earth element (LREE)-rich inclusions in garnet, which can complicate Sm-Nd geochronology. Samples were taken from several locations from both along and perpendicular to the suture zone. We report results on two of these samples, within and east of the WISZ. First, a garnet bearing leucocratic layer in a gneissic meta-sedimentary screen near Cascade, Idaho, yields a garnet age of 98 ± 2.0 Ma (2SD). The screen occurs completely within the orthogneisses of the WISZ, and displays similar fabrics and kinematics. Second, a biotite quartzo-feldspathic garnet gneiss from Elk City, Idaho, yields an age 100 ± 2.9 Ma (2SD). This location is ~35 km east of the WISZ, on a sub-parallel deformation zone that was active at the same time. Both samples were single-stage garnet fractions consisting of inclusion-free to inclusion-bearing fragments and whole rock pairs. These ages provide two important implications for the Mesozoic evolution of the western edge of North America. First, transpressional deformation in the WISZ occurred simultaneously with deformation on parallel structures in central Idaho, indicating that a wide zone of deformation

    The purpose of this study is to assess the design and operation of rotary drum screens. Chinook salmon Oncorhynchus tshawytscha and steelhead O. mykiss are the potentially affected fish. Cold-branded fish are released upstream of the screen facilities. For descaling tests, the fish are captured as they exit the facility and are examined for injuries, descaling, and post-test mortalities. For screen passage tests, nets are placed in the irrigation ditch, downstream of the screen facilities, to determine if fish can pass through or over the screens. More than 100 tests have been conducted with almost 35,000 fish. Additionally, nearly 2000 native fish have been evaluated. Usually less than 2% of the test fish are injured or dead, and the condition of test fish does not differ from the controls. Less than 2% of the fish pass through or over the screens when the screen seals are properly installed and maintained.

    Anadromous fish populations in the Columbia River Basin have plummeted in the last 100 years. This severe decline led to Federal listing of chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) stocks as endangered or threatened under the Endangered Species Act (ESA) in the 1990s. Historically, the upper Salmon River Basin (upstream from the confluence with the Pahsimeroi River) in Idaho provided migration corridors and significant habitat for these ESA-listed species, in addition to the federally listed bull trout (Salvelinus confluentus). Human development has modified the original streamflow conditions in many streams in the upper Salmon River Basin. Summer streamflow modifications, as a result of irrigation practices, have directly affected the quantity and quality of fish habitat and also have affected migration and (or) access to suitable spawning and rearing habitat for these fish. As a result of these ESA listings and Action 149 of the Federal Columbia River Power System Biological Opinion of 2000, the Bureau of Reclamation was tasked to conduct streamflow characterization studies in the upper Salmon River Basin to clearly define habitat requirements for effective species management and habitat restoration. These studies include the collection of habitat and streamflow information for the Physical Habitat Simulation (PHABSIM) model, a widely applied method to determine relations between habitat and discharge requirements for various fish species and life stages. Model results can be used by resource managers to guide habitat restoration efforts in the evaluation of potential fish habitat and passage improvements by increasing streamflow. Instream flow characterization studies were completed on Pole, Fourth of July, Elk, and Valley Creeks during 2003. Continuous streamflow data were collected upstream from all diversions on each stream. In addition, natural summer streamflows were estimated for each study site using regression

    At the end of May 2007, 830 and 2600 kilograms of EBR-II driver and blanket metal fuel have been treated by a pyroprocess since spent fuel operations began in June 1996. A new metal waste furnace has completed out-of-cell testing and is being installed in the Hot Fuel Examination Facility. Also, ceramic waste process development and qualification is progressing so integrated nuclear fuel separations and high level waste processes will exist at Idaho National Laboratory. These operations have provided important scale-up and performance data on engineering scale operations. Idaho National Laboratory is also increasing their laboratory scale capabilities so new process improvements and new concepts can be tested before implementation at engineering scale. This paper provides an overview of recent achievements and provides the interested reader references for more details.

    On April 14, 1973, a magnitude 4.75 earthquake occurred in Oneida County, Idaho. The intensity of ground motion was too slight to cause damage, and local interest in this event was so slight that it was not even noted in the weekly newspaper, the Idaho Enterprise, published in Malad City, the county seat. Two years later, an earthquake of magnitude 6.1 and three shocks, each of a magnitude greater than 4, occurred in nearly the same place under Pocatello Valley (fig 1). The main shock on March 27, 1975, was the strongest in the United States since the 1971 San Fernando Valley, Calif., event and was reported in newspapers across the country.

    In response to decreasing funding levels available to support activities at the Idaho Chemical Processing Plant (ICPP) and a desire to be cost competitive, the Department of Energy Idaho Operations Office (DOE-ID) and Lockheed Idaho Technologies Company have increased their emphasis on cost-saving measures. The ICPP Effectiveness Improvement Initiative involves many activities to improve cost effectiveness and competitiveness. This report documents the methodology and results of one of those cost cutting measures, the Process Efficiency Improvement Activity. The Process Efficiency Improvement Activity performed a systematic review of major work processes at the ICPP to increase productivity and to identify nonvalue-added requirements. A two-phase approach was selected for the activity to allow for near-term implementation of relatively easy process modifications in the first phase while obtaining long-term continuous improvement in the second phase and beyond. Phase I of the initiative included a concentrated review of processes that had a high potential for cost savings with the intent of realizing savings in Fiscal Year 1996 (FY-96.) Phase II consists of implementing long-term strategies too complex for Phase I implementation and evaluation of processes not targeted for Phase I review. The Phase II effort is targeted for realizing cost savings in FY-97 and beyond.

    1987-01-01

    The major aquifers in Idaho are categorized under two rock types, sedimentary and volcanic, and are grouped into six hydrologic basins. Areas with adequate, minimally adequate, or deficient data available for groundwater-quality evaluations are described. Wide variations in chemical concentrations in the water occur within individual aquifers, as well as among the aquifers. The existing data base is not sufficient to describe fully the ground-water quality throughout the State; however, it does indicate that the water is generally suitable for most uses. In some aquifers, concentrations of fluoride, cadmium, and iron in the water exceed the U.S. Environmental Protection Agency's drinking-water standards. Dissolved solids, chloride, and sulfate may cause problems in some local areas. Water-quality data are sparse in many areas, and only general statements can be made regarding the areal distribution of chemical constituents. Few data are available to describe temporal variations of water quality in the aquifers. Primary concerns related to special problem areas in Idaho include (1) protection of water quality in the Rathdrum Prairie aquifer, (2) potential degradation of water quality in the Boise-Nampa area, (3) effects of widespread use of drain wells overlying the eastern Snake River Plain basalt aquifer, and (4) disposal of low-level radioactive wastes at the Idaho National Engineering Laboratory. Shortcomings in the ground-water-quality data base are categorized as (1) multiaquifer sample inadequacy, (2) constituent coverage limitations, (3) baseline-data deficiencies, and (4) data-base nonuniformity.

    The Hells Canyon Complex (HCC) is a hydroelectric project built and operated by the Idaho Power Company (IPC) that consists of three dams on the Snake River along the Oregon and Idaho border (fig. 1). The dams have resulted in the creation of Brownlee, Oxbow, and Hells Canyon Reservoirs, which have a combined storage capacity of more than 1.5 million acre-feet and span about 90 miles of the Snake River. The Snake River upstream of and through the HCC historically has been impaired by water-quality issues related to excessive contributions of nutrients, algae, sediment, and other pollutants. In addition, historical data collected since the 1960s from the Snake River and tributaries near the HCC have documented high concentrations of mercury in fish tissue and sediment (Harris and Beals, 2013). Data collected from more recent investigations within the HCC continue to indicate elevated concentrations of mercury and methylmercury in the water column, bottom sediments, and biota (Clark and Maret, 1998; Essig, 2010; Fosness and others, 2013). As a result, Brownlee and Hells Canyon Reservoirs are listed as impaired for mercury by the State of Idaho, and the Snake River from the Oregon and Idaho border through the HCC downstream to the Oregon and Washington border is listed as impaired for mercury by the State of Oregon.

    2007-01-01

    An important issue surrounding biomonitoring in large rivers is the minimum sampling effort required to collect an adequate number of fish for accurate and precise determinations of biotic condition. During the summer of 2002, we sampled 15 randomly selected large-river sites in southern Idaho to evaluate the effects of sampling effort on an index of biotic integrity (IBI). Boat electrofishing was used to collect sample populations of fish in river reaches representing 40 and 100 times the mean channel width (MCW; wetted channel) at base flow. Minimum sampling effort was assessed by comparing the relation between reach length sampled and change in IBI score. Thirty-two species of fish in the families Catostomidae, Centrarchidae, Cottidae, Cyprinidae, Ictaluridae, Percidae, and Salmonidae were collected. Of these, 12 alien species were collected at 80% (12 of 15) of the sample sites; alien species represented about 38% of all species (N = 32) collected during the study. A total of 60% (9 of 15) of the sample sites had poor IBI scores. A minimum reach length of about 36 times MCW was determined to be sufficient for collecting an adequate number of fish for estimating biotic condition based on an IBI score. For most sites, this equates to collecting 275 fish at a site. Results may be applicable to other semiarid, fifth-order through seventh-order rivers sampled during summer low-flow conditions. ??

    Underwater time- lapse video technology has been used to monitor adult spring and summer chinook salmon (Oncorhynchus tshawytscha) escapement into the Secesh River and Lake Creek, Idaho, since 1998. Underwater time-lapse videography is a passive methodology that does not trap or handle this Endangered Species Act listed species. Secesh River chinook salmon represent a wild spawning aggregate that has not been directly supplemented with hatchery fish. The Secesh River is also a control stream under the Idaho Salmon Supplementation study. This project has successfully demonstrated the application of underwater video monitoring to accurately quantify chinook salmon abundance in Lake Creek in 1998, 1999, 2001 and 2002. The adult salmon spawner escapement into Lake Creek in 2002 was 410 fish. Jack salmon comprised 7.1 percent of the run. Estimated hatchery composition was 6.1 percent of the spawning run. The first fish passage on Lake Creek was recorded on June 26, 15 days after installation of the fish counting station. Peak net upstream movement of 41 adults occurred on July 8. Peak of total movement activity was August 18. The last fish passed through the Lake Creek fish counting station on September 2. Snow pack in the drainage was 91% of the average during the winter of 2001/2002. Video determined salmon spawner abundance was compared to redd count expansion method point estimates in Lake Creek in 2002. Expanded index area redd count and extensive area redd count point estimates in 2002, estimated from one percent fewer to 56 percent greater number of spawners than underwater video determined spawner abundance. Redd count expansion methods varied from two percent fewer to 55 percent greater in 2001, 11 to 46 percent fewer in 1999 and 104 to 214 percent greater in 1998. Redd count expansion values had unknown variation associated with the point estimates.

The Secesh River is also a control stream under the Idaho Salmon Supplementation study. This project has successfully demonstrated the application of underwater video monitoring to accurately quantify chinook salmon abundance in Lake Creek in 1998, 1999 and 2001. The adult salmon spawner escapement estimate into Lake Creek in 2001 was 697 fish, the largest escapement since the project began. Jack salmon comprised 10% of the spring migration. Snow pack in the drainage was 38% of the average during the winter of 2000/2001. The first fish passage on Lake Creek was recorded on June 9, 19 days after installation of the fish counting station and two weeks earlier than previously reported. Peak net upstream movement of 52 adults occurred on June 22. Peak of total movement activity was July 3. The last fish passed through the Lake Creek fish counting station on September 6. Redd count expansion methods were compared to underwater video determined salmon spawner abundance in Lake Creek in 2001. Expanded index area redd count point estimates and intensive area redd counts in 2001, estimated from 1.3 percent fewer to 56 percent greater number of spawners than underwater video determined spawner abundance. Redd count expansion values had unknown variation associated with the point estimates. Fish per redd numbers in Lake Creek have varied widely. In 2001 there were 2.07 fish per redd. In 1999, there were 3.58 fish per redd, and in 1998, with no jacks returning to spawn, there were 1.02 fish per redd. Migrating salmon in Lake Creek

Underwater time-lapse videography is a passive methodology that does not trap or handle this Endangered Species Act listed species. Secesh River chinook salmon represent a wild spawning aggregate that has not been directly supplemented with hatchery fish. The Secesh River is also a control population under the Idaho Salmon Supplementation study. This project has demonstrated the successful application of underwater video adult salmon abundance monitoring technology in Lake Creek in 1998 and 1999. Emphasis of the project in 2000 was to determine if the temporary fish counting station could be installed early enough to successfully estimate adult spring and summer chinook salmon abundance in the Secesh River (a larger stream). Snow pack in the drainage was 93% of the average during the winter of 1999/2000, providing an opportunity to test the temporary count station structure. The temporary fish counting station was not the appropriate technology to determine adult salmon spawner abundance in the Secesh River. Due to its temporary nature it could not be installed early enough, due to high stream discharge, to capture the first upstream migrating salmon. A more permanent structure used with underwater video, or other technology needs to be utilized for accurate salmon escapement monitoring in the Secesh River. A minimum of 813 adult chinook salmon spawners migrated upstream past the Secesh River fish counting station to spawning areas in the Secesh River drainage. Of these fish, more than 324 migrated upstream into Lake Creek. The first upstream migrating adult chinook salmon passed the Secesh River and Lake Creek sites prior to operation of the fish counting stations on June 22. This was 17 and 19 days earlier than the first fish arrival at Lake Creek in 1998 and 1999

    The U. S. Department of Energy, Idaho Operations Office is considering options for construction of a facility for disposal of Idaho National Laboratory (INL) generated remote-handled low-level waste. Initial screening has resulted in the identification of two recommended alternative locations for this new facility: one near the Advanced Test Reactor (ATR) Complex and one near the Idaho Comprehensive Environmental Response, Compensation, and Liability Act Disposal Facility (ICDF). In April and May of 2010, the INL Cultural Resource Management Office conducted archival searches, intensive archaeological field surveys, and initial coordination with the Shoshone-Bannock Tribes to identify cultural resources that may be adversely affected by new construction within either one of these candidate locations. This investigation showed that construction within the location near the ATR Complex may impact one historic homestead and several historic canals and ditches that are potentially eligible for nomination to the National Register of Historic Places. No resources judged to be of National Register significance were identified in the candidate location near the ICDF. Generalized tribal concerns regarding protection of natural resources were also documented in both locations. This report outlines recommendations for protective measures to help ensure that the impacts of construction on the identified resources are not adverse.

    An independent assessment of the remediation of the BORAX-V (Boiling Water Reactor Experiment) turbine building at the Idaho National Engineering Laboratory (INEL), Idaho Falls, Idaho, was accomplished by the Oak Ridge National Laboratory Pollutant Assessments Group (ORNL/PAG). The purpose of the assessment was to confirm the site`s compliance with applicable Department of Energy guidelines. The assessment included reviews of both the decontamination and decommissioning Plan and data provided from the pre- and post-remedial action surveys and an independent verification survey of the facility. The independent verification survey included determination of background exposure rates and soil concentrations, beta-gamma and gamma radiation scans, smears for detection of removable contamination, and direct measurements for alpha and beta-gamma radiation activity on the basement and mezzanine floors and the building`s interior and exterior walls. Soil samples were taken, and beta-gamma and gamma radiation exposure rates were measured on areas adjacent to the building. Results of measurements on building surfaces at this facility were within established contamination guidelines except for elevated beta-gamma radiation levels located on three isolated areas of the basement floor. Following remediation of these areas, ORNL/PAG reviewed the remedial action contractor`s report and agreed that remediation was effective in removing the source of the elevated direct radiation. Results of all independent soil analyses for {sup 60}Co were below the detection limit. The highest {sup 137}Cs analysis result was 4.6 pCi/g; this value is below the INEL site-specific guideline of 10 pCi/g.

    The study described in this report evaluated spawning distribution, overlap with naturally-arriving spawners, and pre-spawning mortality of spring chinook salmon, Oncorhynchus tshawytscha, outplanted as adults in the Clearwater River Subbasin in 2001. Returns of spring chinook salmon to Snake River Basin hatcheries and acclimation facilities in 2001 exceeded needs for hatchery production goals in Idaho. Consequently, management agencies including the U.S. Fish and Wildlife Service (FWS), Idaho Department of Fish and Game (IDFG) and Nez Perce Tribe (NPT) agreed to outplant chinook salmon adults as an adaptive management strategy for using hatchery adults. Adult outplants were made in streams or stream sections that have been typically underseeded with spawners. This strategy anticipated that outplanted hatchery chinook salmon would spawn successfully near the areas where they were planted, and would increase natural production. Outplanting of adult spring chinook salmon from hatcheries is likely to be proposed in years when run sizes are similar to those of the 2001 run. Careful monitoring of results from this year's outplanting can be used to guide decisions and methods for future adult outplanting. Numbers of spring chinook salmon outplanted was based on hatchery run size, hatchery needs, and available spawning habitat. Hatcheries involved in outplanting in the Clearwater Basin included Dworshak National Fish Hatchery, Kooskia National Fish Hatchery, Clearwater Anadromous Fish Hatchery, and Rapid River Fish Hatchery. The NPT, IDFG, FWS, and the National Marine Fisheries Service (NMFS) agreed upon outplant locations and a range of numbers of spring chinook salmon to be outplanted (Table 1). Outplanting occurred mainly in the Selway River Subbasin, but additional outplants were made in tributaries to the South Fork Clearwater River and the Lochsa River (Table 1). Actual outplanting activities were carried out primarily by the NPT with supplemental outplanting done

    We collected eggs in nests, hatchlings and eggs with advanced embryos on the ground, and prefledgling young of Great Blue Herons (Ardea herodias) at three nesting colonies in Washington and Idaho. Intact fish were also collected on the ground at the Idaho colony. The Ft. Lewis colony near Puget Sound in Washington and the Lake Chatcolet colony in northern Idaho were located near areas extensively polluted with heavy metals from minning or smelting activities. The Hanford Reservation colony near Richland, Washington was located some distance from point sources of heavy metal pollution. Heavy metals in heron samples were generally low and were all below concentrations known to induce mortality or adversely affect reproductive success. The elevated copper in one of three prefledglings from Ft. Lewis paralleled that found in an occasional nestling of several species of birds in other studies; the significance of this relationship is unclear. Breeding herons apparently fed near their colonies in areas removed from the sites of heaviest contamination, but birds in the Lake Chatcolet colony were preying on fish containing as much as 6 mu-g/g lead.

  14. Feasibility study for the City of Twin Falls Sewage Hydroelectric Project in Twin Falls County, Idaho

    1981-08-01

    The City of Twin Falls, Idaho authorized J-U-B Engineers, Inc., to assess the feasibility of installing a small hydropower plant on the discharge of the City's Grandview sewage trunk line. The concept of developing hydropower from sewage flow is novel and may have applications in other areas of the nation if its technical feasibility can be established. No conventional turbine would be suitable in this application without extensively screening the influent. Therefore, finding a turbine which would work satisfactorily, was one of the major aspects of the study. A solution to this problem was found in a staged, non-clog, hydraulic turbine manufactured by Cornell Pump Co. A preliminary design configuration is presented using these turbines. The economical feasibility of the project depends on future sewage flows from Idaho Frozen Foods Company, a large contributor to the present Twin Falls sewage flows. The yearly revenue, would decrease by about one-third, if Idaho Frozen Foods disconnects from the City's sewage system. Therefore, the project is less feasible, economically, without the flow contributed by Idaho Frozen Foods. The cost of energy production is 47 mils per kilowatt-hour (kWh) with this flow, and about 60 mils/kWh without this flow. At the higher flow rate (5 cfs) the total capital investment is estimated to be $270,200 or approximately $2250 per installed kW capacity. Estimated annual energy production at 5.0 cfs is 440,650 kWh with a subsequent first year annual revenue of $59,460. Power could be put on line within nine months of the time the Twin Falls City Council makes a decision to develop the project.

  15. Classification of species attributes for Pacific Northwest freshwater fishes

    1999-01-01

    Fish assemblages integrate physical and chemical habitat conditions and are used to evaluate the condition of water resources in the Pacific Northwest. To facilitate such evaluations, we classified each of the 132 freshwater fish species known to occur in the Pacific Northwest (Idaho, Oregon, Washington) by its origin, overall pollution tolerance, adult habitat, adult feeding, and water temperature preference. Recommendations from regional fishery experts, published literature, and the aggregate experience of the authors were used to classify species. The attribute classifications were responsive to human disturbance of aquatic habitats when applied to fish assemblages sampled from throughout the region. Our attribute classification of fish species promotes use of fish assemblages to evaluate water resource conditions regionally and fosters greater acceptance of biological measures of water resource quality.

    Warren, James W.

    1989-08-15

    Augmented Fish Health Monitoring Contract AI79-87BP35585 was implemented on July 20, 1987. Second year activities focused on full implementation of disease surveillance activities and histopathological support services to participating state agencies. Persistent and sometimes severe disease losses were caused by infectious hematopoietic necrosis (IHN) in summer steelhead trout in Idaho and in spring chinook salmon at hatcheries on the lower Columbia River. Diagnostic capability was enhanced by the installation, for field use, of enzyme-linked immunosorbent assay (ELISA) technology at the Dworshak Fish Health Center for the detection and assay of bacterial kidney disease and by a dot-blot'' training session for virus identification at the Lower Columbia Fish Health Center. Complete diagnostic and inspection services were provided to 13 Columbia River basin National Fish hatcheries. Case history data was fully documented in a computerized data base for storage and analysis. This report briefly describes work being done to meet contract requirements for fish disease surveillance at Service facilities in the Columbia River basin. It also summarizes the health status of fish reared at those hatcheries and provides a summary of case history data for calendar year 1988. 2 refs., 4 tabs.

    1990-10-01

    The objective of this project was to evaluate and test solids removal techniques from wastewater and sludge disposal technology for the fish farming industry of southern Idaho. This work provided scientists and engineers from the Department of Energy's Idaho National Engineering Laboratory (INEL) opportunities to: explore and promote the conversion of a waste product to an energy source (i.e., fertilizer) and expand knowledge in the treatment of low strength wastewaters that affect the quality of water resources. Specifically, our concern was the removal and utilization of solids that could pollute surface waters. This project was a collaborative effort between the Idaho Aquaculture Association (IAA), the College of Southern Idaho (CSI), state and federal agricultural agencies, and state universities. 40 refs., 8 figs., 1 tab.

    2001-03-01

    Tribal people in southeast Idaho sincerely desire that archaeologists include Shoshone concepts of spirituality when investigating archaeological materials and sites. However, most archaeologists and resource managers have little understanding about these concepts and this creates difficulties. We examine two important aspects of the Shoshone soul, Mugua’ and Nabushi’aipe, and discuss how understanding these attributes aid in explaining why certain archaeological remains are considered sacred. A greater understanding of Shoshone spirituality will begin to bridge the needs of both tribal people and archaeologists.

    1986-01-01

    The purpose of the project was to achieve full chinook salmon and steelhead trout production in the Panther Creek, Idaho, basin. Plans were developed to eliminate the sources of toxic effluent entering Panther Creek. Operation of a cobalt-copper mine since the 1930's has resulted in acid, metal-bearing drainage entering the watershed from underground workings and tailings piles. The report discusses plans for eliminating and/or treating the effluent to rehabilitate the water quality of Panther Creek and allow the reestablishment of salmon and trout spawning runs. (ACR)

    1984-01-01

    Geologic, geophysical, and geochemical surveys, and an examination of mines and prospects were made in the Mount Naomi Roadless Area, Utah and Idaho. No significant precious-metal, base-metal, other trace-metal, or uranium anomalies are apparent in the geochemical data from the Mount Naomi Roadless Area, and no exploration targets were detected. However, a belt of probable resource potential for stratabound copper, lead, and zinc occurrences exists on the west side of the area in limestone and shale. The possibility that oil and gas concentration lie deeply buried beneath the roadless area cannot be evaluated from available data.

    During 2015, the U.S. Geological Survey, in cooperation with the U.S. Department of Energy, collected groundwater samples from 31 wells at or near the Idaho Nuclear Technology and Engineering Center (INTEC) at the Idaho National Laboratory for purgeable organic compounds (POCs). The samples were collected and analyzed for the purpose of evaluating whether purge water from wells located inside an areal polygon established downgradient of the INTEC must be treated as a Resource Conservation and Recovery Act listed waste.POC concentrations in water samples from 29 of 31 wells completed in the eastern Snake River Plain aquifer were greater than their detection limit, determined from detection and quantitation calculation software, for at least one to four POCs. Of the 29 wells with concentrations greater than their detection limits, only 20 had concentrations greater than the laboratory reporting limit as calculated with detection and quantitation calculation software. None of the concentrations exceeded any maximum contaminant levels established for public drinking water supplies. Most commonly detected compounds were 1,1,1-trichoroethane, 1,1-dichloroethene, and trichloroethene.

    Parma were higher than those in undeveloped basins sampled nationwide by the USGS. Total phosphorus concentrations at Glenwood, Middleton, and Parma also exceeded those in undeveloped basins. Macroinvertebrate and fish communities were used to evaluate the long-term integration of water-quality contaminants and loss of habitat in the lower Boise. Biological integrity of the macroinvertebrate population was assessed with the attributes (metrics) of Ephemeroptera, Plecoptera, and Trichoptera (EPT) richness and metrics used in the Idaho River Macroinvertebrate Index (RMI): taxa richness; EPT richness; percent dominant taxon; percent Elmidae (riffle beetles); and percent predators. Average EPT was about 10, and RMI scores were frequently below 16, which indicated intermediate or poor water quality. The number of EPT taxa and RMI scores for the lower Boise were half those for least-impacted streams in Idaho. The fine sediment bioassessment index (FSBI) was used to evaluate macroinvertebrate sediment tolerance. The FSBI scores were lower than those for a site upstream in the Boise River Basin near Twin Springs, a site not impacted by urbanization and agriculture, which indicated that the lower Boise macroinvertebrate population may be impacted by fine sediment. Macroinvertebrate functional feeding groups and percent tolerant species, mainly at Middleton and Parma, were typical of those in areas of degraded water quality and habitat. The biological integrity of the fish population was evaluated using the Idaho River Fish Index (RFI), which consists of the 10 metrics: number of coldwater native species, percent sculpin, percent coldwater species, percent sensitive native individuals, percent tolerant individuals, number of nonindigenous species, number of coldwater fish captured per minute of electrofishing, percent of fish with deformities (eroded fins, lesions, or tumors), number of trout age classes, and percent carp.

    Mancuso, Michael; Moseley, Robert

    1994-12-01

    The Craig Mountain Wildlife Mitigation Area was purchased by Bonneville Power Administration (BPA) as partial mitigation for wildlife losses incurred with the inundation of Dworshak Reservoir on the North Fork Clearwater River. Upon completion of the National Environmental Protection Act (NEPA) process, it is proposed that title to mitigation lands will be given to the Idaho Department of Fish and Game (IDFG). Craig Mountain is located at the northern end of the Hells Canyon Ecosystem. It encompasses the plateau and steep canyon slopes extending from the confluence of the Snake and Salmon rivers, northward to near Waha, south of Lewiston, Idaho. The forested summit of Craig Mountain is characterized by gently rolling terrain. The highlands dramatically break into the canyons of the Snake and Salmon rivers at approximately the 4,700 foot contour. The highly dissected canyons are dominated by grassland slopes containing a mosaic of shrubfield, riparian, and woodland habitats. During the 1993 and 1994 field seasons, wildlife, habitat/vegetation, timber, and other resources were systematically inventoried at Craig Mountain to provide Fish and Game managers with information needed to draft an ecologically-based management plan. The results of the habitat/vegetation portion of the inventory are contained in this report. The responsibilities for the Craig Mountain project included: (1) vegetation data collection, and vegetation classification, to help produce a GIS-generated Craig Mountain vegetation map, (2) to determine the distribution and abundance of rare plants populations and make recommendations concerning their management, and (3) to establish a vegetation monitoring program to evaluate the effects of Fish and Game management actions, and to assess progress towards meeting habitat mitigation goals.

To that end, TVA conducts the Water Resources and Biological Monitoring Program that includes physical, chemical, and biological data collection components. Biological monitoring targets the following selected elements within three zones of the reservoir (inflow, transition, and forebay): Sediment/Water-column Acute Toxicity Screening (forebay and transition zone only); Benthic macroinvertebrates Fish Reservoir fish monitoring is divided into the following activities: Fish Biomass; Fish Tissue Contamination; Fish Community Monitoring; Fish Health Assessment. This report presents the results of fall1991 fish community monitoring and fish health assessment data using a new analytical approach: Reservoir Index of Biotic Integrity (RIBI). Fish health assessment is included in this report as one of the RIBI metrics.

    The U.S. Geological Survey (USGS) Project Office at the Idaho National Engineering Laboratory (INEL), in cooperation with the U.S. Department of Energy and Idaho State University, analyzed 66 samples from sedimentary interbed cores during a 38-month period beginning in October 1990 to determine bulk and clay mineralogy. These cores had been collected from 19 sites in the Big Lost River Basin, 2 sites in the Birch Creek Basin, and 1 site in the Mud Lake Basin, and were archived at the USGS lithologic core library at the INEL. Mineralogy data indicate that the core samples from the Big Lost River Basin have larger mean and median percentages of quartz, total feldspar, and total clay minerals, but smaller mean and median percentages of calcite than the core samples from the Birch Creek Basin. Core samples from the Mud Lake Basin have abundant quartz, total feldspar, calcite, and total clay minerals.

    The Bonneville Power Administration (BPA) initiated the Augmented Fish Health Monitoring project in 1986. This project was a five year interagency project involving fish rearing agencies in the Columbia Basin. Participating agencies included: Washington Department of Fisheries (WDF), Oregon Department of Fish and Wildlife, Idaho Department of Fish and Game, and the US Fish and Wildlife Service (USFWS). This is the final data report for the Augmented Fish Health Monitoring project. Data collected and sampling results for 1990 and 1991 are presented within this report. An evaluation of this project can be found in Augmented Fish Health Monitoring, Volume 1, Completion Report.'' May, 1991. Pathogen detection methods remained the same from methods described in Augmented Fish Health Monitoring, Annual Report 1989,'' May, 1990. From January 1, 1990 to June 30, 1991 fish health monitoring sampling was conducted. In 1990 21 returning adult stocks were sampled. Juvenile pre-release exams were completed on 20 yearling releases, and 13 sub-yearling releases in 1990. In 1991 17 yearling releases and 11 sub-yearling releases were examined. Midterm sampling was completed on 19 stocks in 1990. Organosomatic analysis was performed at release on index station stocks; Cowlitz spring and fall chinook, Lewis river early coho and Lyons Ferry fall chinook.

    This volume includes a series of four exhibits relating to impacts of impingement on fish populations, together with a collection of critical evaluations of testimony prepared for the utilities by their consultants. The first exhibit is a quantitative evaluation of four sources of bias (collection efficiency, reimpingement, impingement on inoperative screens, and impingement survival) affecting estimates of the number of fish killed at Hudson River power plants. The two following exhibits contain, respectively, a detailed assessment of the impact of impingement on the Hudson River white perch population and estimates of conditional impingement mortality rates for seven Hudson River fish populations. The fourth exhibit is an evaluation of the engineering feasibility and potential biological effectiveness of several types of modified intake structures proposed as alternatives to cooling towers for reducing impingement impacts. The remainder of Volume II consists of critical evaluations of the utilities' empirical evidence for the existence of density-dependent growth in young-of-the-year striped bass and white perch, of their estimate of the age-composition of the striped bass spawning stock in the Hudson River, and of their use of the Lawler, Matusky, and Skelly (LMS) Real-Time Life Cycle Model to estimate the impact of entrainment and impingement on the Hudson River striped bass population.

    1992-10-01

    The Idaho Water Rental Pilot Project was implemented as a part of the Non-Treaty Storage Fish and Wildlife Agreement (NTSA) between Bonneville Power Administration and the Columbia Basin Fish and Wildlife Authority. The goal of the project is to improve juvenile and adult salmon and steelhead passage in the lower Snake River with the use of rented water for flow augmentation. The primary purpose of this project is to summarize existing resource information and provide recommendations to protect or enhance resident fish and wildlife resources in Idaho with actions achieving flow augmentation for anadromous fish. Potential impacts of an annual flow augmentation program on Idaho reservoirs and streams are modeled. Potential sources of water for flow augmentation and operational or institutional constraints to the use of that water are identified. This report does not advocate flow augmentation as the preferred long-term recovery action for salmon. The state of Idaho strongly believes that annual drawdown of the four lower Snake reservoirs is critical to the long-term enhancement and recovery of salmon (Andrus 1990). Existing water level management includes balancing the needs of hydropower production, irrigated agriculture, municipalities and industries with fish, wildlife and recreation. Reservoir minimum pool maintenance, water quality and instream flows are issues of public concern that will be directly affected by the timing and quantity of water rental releases for salmon flow augmentation, The potential of renting water from Idaho rental pools for salmon flow augmentation is complicated by institutional impediments, competition from other water users, and dry year shortages. Water rental will contribute to a reduction in carryover storage in a series of dry years when salmon flow augmentation is most critical. Such a reduction in carryover can have negative impacts on reservoir fisheries by eliminating shoreline spawning beds, reducing available fish habitat

    The INEL underwent a year of transition in 1986. Success with new business initiatives, the prospects of even better things to come, and increased national recognition provided the INEL with a glimpse of its promising and exciting future. Among the highlights were: selection of the INEL as the preferred site for the Special Isotope Separation Facility (SIS); the first shipments of core debris from the Three Mile Island Unit 2 reactor to the INEL; dedication of three new facilities - the Fluorinel Dissolution Process, the Remote Analytical Laboratory, and the Stored Waste Experimental Pilot Plant; groundbreaking for the Fuel Processing Restoration Facility; and the first IR-100 award won by the INEL, given for an innovative machine vision system. The INEL has been assigned project management responsibility for the SDI Office-sponsored Multimegawatt Space Reactor and the Air Force-sponsored Multimegawatt Terrestrial Power Plant Project. New Department of Defense initiatives have been realized in projects involving development of prototype defense electronics systems, materials research, and hazardous waste technology. While some of our major reactor safety research programs have been completed, the INEL continues as a leader in advanced reactor technologies development. In April, successful tests were conducted for the development of the Integral Fast Reactor. Other 1986 highlights included the INEL's increased support to the Office of Civilian Radioactive Waste Management for complying with the Nuclear Waste Policy Act of 1982. Major INEL activities included managing a cask procurement program, demonstrating fuel assembly consolidation, and testing spent fuel storage casks. In addition, the INEL supplied the Tennessee Valley Authority with management and personnel experienced in reactor technology, increased basic research programs at the Idaho Research Center, and made numerous outreach efforts to assist the economies of Idaho communities.

  18. Dynamics of an introduced and unexploited Lake Whitefish population in Lake Pend Oreille, Idaho

    2014-01-01

    To evaluate biological potential of a commercial fishery for an unexploited Lake Whitefish Coregonus clupeaformis population in Lake Pend Oreille, Idaho, we estimated population parameters related to production and yield. The length frequency based on trap-netting in autumn 2005 was normal with a mean of 448 mm TL, whereas the length frequency based on gillnetting in spring 2006 was bimodal with a mean of 390 mm TL. Sex composition was skewed toward females (0.66) during autumn trap-netting. Shape parameters β of weight–length models for females (β = 3.38) and males (β = 3.45) were similar to those of other unexploited populations. Instantaneous growth rates K for females (K = 0.144 per year) and males (K = 0.153 per year) were among the lowest for unexploited populations across the species’ range. Age at 50% maturity (females: 6.5 years; males: 6.0 years) and length at 50% maturity (females: 390 mm TL; males: 378 mm TL) were high for unexploited populations. The natural mortality rate M (0.149 per year, ages 11–36) was among the lowest observed for unexploited populations. Adult population density was lower than that of other populations based on total surface area (mean = 1.35 fish/ha; 95% confidence interval [CI] = 1.11–1.78 fish/ha) but was average based on lake area shallower than 70 m (4.07 fish/ha; 95% CI = 3.35–5.35 fish/ha). Population density of juveniles and adults averaged 84 fish/ha (95% CI = 52–143 fish/ha) over the entire surface area and 278 fish/ha (95% CI = 173–474 fish/ha) over depths shallower than 70 m. The difference between the low M of the unexploited population in Lake Pend Oreille (M = 0.149 per year; annual mortality rate A = 14%) and the high sustainable total mortality Z of exploited stocks in the Laurentian Great Lakes (Z = 1.204; A = 70%) suggests a large scope for sustainable fishing mortality F (1.055 per year; exploitation rate u = 61%) that is equivalent to a sustainable Lake Whitefish harvest of 55

    We present new P-to-S receiver functions at 86 broadband seismic stations that we deployed in Eastern Oregon and Western Idaho as part of the IDOR (IDaho-ORegon) Earthscope project. We obtained a 3D lithospheric image detailing the crustal structure and architecture of the Idaho Batholith and Salmon River suture/Western Idaho Shear Zone (WISZ) at depth. The suture marks the sharp ~110-90 Ma contact between the accreted oceanic terranes (Blue Mountains province) and the North American Craton and is characterized largely by the near vertical dextral transpressional system of the WISZ, which closely follows the Sr 0.706 isopleth. The Idaho Batholith (Atlanta and Bitterroot lobes) is characterized by long-lived magmatism ranging between 108 and 50 Ma occurring during and after the deformation in the WISZ. To understand the evolution of this portion of the western North American plate boundary and the transition from Mesozoic transpressional tectonics west of the Idaho batholith to current basin-and-range-like tectonics to the east, we analyzed more than 350 teleseismic events generated at epicentral distances between 30 and 95 degrees. We constructed receiver functions using a modified version of the Ligorria and Ammon (1999) iterative deconvolution technique, and then applied the H-k stacking procedure of Zhu and Kanamori (2000) for each station to estimate Vp/Vs ratios and depths to different boundary interfaces. In addition we applied the common conversion point stacking method (CCP) of Dueker and Sheehan (1997) for bins of receiver functions. Preliminary results show an important variation of the crustal thickness beneath the IDOR area, with a thicker crust beneath the Atlanta lobe of the Idaho Batholith.

    The Steelhead Supplementation Study (SSS) has two broad objectives: (1) investigate the feasibility of supplementing depressed wild and natural steelhead populations using hatchery populations, and (2) describe the basic life history and genetic characteristics of wild and natural steelhead populations in the Salmon and Clearwater Basins. Idaho Department of Fish and Game (IDFG) personnel stocked adult steelhead from Sawtooth Fish Hatchery into Frenchman and Beaver creeks and estimated the number of age-1 parr produced from the outplants since 1993. On May 2, 2002, both Beaver and Frenchman creeks were stocked with hatchery adult steelhead. A SSS crew snorkeled the creeks in August 2002 to estimate the abundance of age-1 parr from brood year (BY) 2001. I estimated that the yield of age-1 parr per female stocked in 2001 was 7.3 and 6.7 in Beaver and Frenchman creeks, respectively. SSS crews stocked Dworshak hatchery stock fingerlings and smolts from 1993 to 1999 in the Red River drainage to assess which life stage produces more progeny when the adults return to spawn. In 2002, Clearwater Fish Hatchery personnel operated the Red River weir to trap adults that returned from these stockings. Twelve PIT-tagged adults from the smolt releases and one PIT-tagged adult from fingerling releases were detected during their migration up the mainstem Columbia and Snake rivers, but none from either group were caught at the weir. The primary focus of the study has been monitoring and collecting life history information from wild steelhead populations. An adult weir has been operated annually since 1992 in Fish Creek, a tributary of the Lochsa River. The weir was damaged by a rain-on-snow event in April 2002 and although the weir remained intact, some adults were able to swim undetected through the weir. Despite damage to the weir, trap tenders captured 167 adult steelhead, the most fish since 1993. The maximum likelihood estimate of adult steelhead escapement was 242. A screw trap

    Gelatin is a multifunctional ingredient used in foods, pharmaceuticals, cosmetics, and photographic films as a gelling agent, stabilizer, thickener, emulsifier, and film former. As a thermoreversible hydrocolloid with a narrower gap between its melting and gelling temperatures, both of which are below human body temperature, gelatin provides unique advantages over carbohydrate-based gelling agents. Gelatin is mostly produced from pig skin, and cattle hides and bones. Some alternative raw materials have recently gained attention from both researchers and the industry not just because they overcome religious concerns shared by Jews and Muslims but also because they provide, in some cases, technological advantages over mammalian gelatins. Fish skins from a number of fish species are among the other sources that have been comprehensively studied as sources for gelatin production. Fish skins have a significant potential for the production of high-quality gelatin with different melting and gelling temperatures over a much wider range than mammalian gelatins, yet still have a sufficiently high gel strength and viscosity. Gelatin quality is industrially determined by gel strength, viscosity, melting or gelling temperatures, the water content, and microbiological safety. For gelatin manufacturers, yield from a particular raw material is also important. Recent experimental studies have shown that these quality parameters vary greatly depending on the biochemical characteristics of the raw materials, the manufacturing processes applied, and the experimental settings used for quality control tests. In this review, the gelatin quality achieved from different fish species is reviewed along with the experimental procedures used to determine gelatin quality. In addition, the chemical structure of collagen and gelatin, the collagen-gelatin conversion, the gelation process, and the gelatin market are discussed.

    The Idaho Supplementation Studies (ISS) was developed to evaluate the utility of supplementation as a recovery tool for Snake River basin chinook salmon (Supplementation Technical Workgroup 1987), and to help define the potential role of supplementation in managing Idaho's anadromous fisheries (IDFG 1990; IDFG 1992). Supplementation as defined by the Regional Assessment of Supplementation Project group is the use of artificial propagation in the attempt to maintain or increase natural production while maintaining the long-term fitness of the target population (RASP 1992). Poor survival has led to the decline and continued depression of upriver chinook salmon stocks due to mainstem passage and mortality factors associated with the lower Snake and Columbia river dams. Although immediate efforts should focus on alleviating the poor passage and flow conditions, supplementation may concurrently be a viable tool to meet the Northwest Power Planning Council's interim goal of doubling anadromous fish runs in the Columbia River Basin (NPPC 1987) and avoiding short-term loss of spawning aggregates.

    In 2002 Idaho Department of Fish and Game continued investigation into the status of Pacific lamprey populations in Idaho's Clearwater River drainage. Trapping, electrofishing, and spawning ground redd surveys were used to determine Pacific lamprey distribution, life history strategies, and habitat requirements in the South Fork Clearwater River, Lochsa River, Selway River, and Middle Fork Clearwater River subbasins. Five-hundred forty-one ammocoetes were captured electroshocking 70 sites in the South Fork Clearwater River, Lochsa River, Selway River, Middle Fork Clearwater River, Clearwater River, and their tributaries in 2002. Habitat utilization surveys in Red River support previous work indicating Pacific lamprey ammocoete densities are greater in lateral scour pool habitats compared to riffles and rapids. Presence-absence survey findings in 2002 augmented 2000 and 2001 indicating Pacific lamprey macrothalmia and ammocoetes are not numerous or widely distributed. Pacific lamprey distribution was confined to the lower reaches of Red River below rkm 8.0, the South Fork Clearwater River, Lochsa River (Ginger Creek to mouth), Selway River (Race Creek to mouth), Middle Fork Clearwater River, and the Clearwater River (downstream to Potlatch River).

    We studied Bald Eagle foraging ecology on the South Fork Boise River,Idaho, during the winters of 1990-92. We compared habitat variables at 29 foraging sites, 94 perch sites, and 131 random sites.Habitat variables included river habitat (pool, riffle, run), distance to the nearest change in river habitat, distance to nearest available perch, number and species of surrounding perches, and average river depth and flow. Eagles foraged more at pools than expected, and closer( (15 m) to changes in river habitat than expected. Where eagles foraged at riffles, those riffles were slower than riffles where they perched or riffles that were available at random. Where eagles foraged at runs, those runs were shallower than runs at either perch or random sites. Eagles perched less at riffles and more at sites where trees were available than expected. Changes in river habitat represent habitat edges where river depth and flow change, making fish more vulnerable to eagle predation. Fish are more susceptible to predation at shallower river depths and slower flows. Slower river flows may be related to decreased surface turbulence, which also increases vulnerability of fish to aerial predation.

    Anadromous fish populations in the Columbia River Basin have plummeted in the last 100 years. This severe decline led to Federal listing of Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) stocks as endangered or threatened under the Endangered Species Act (ESA) in the 1990s. Historically, the upper Salmon River Basin (upstream of the confluence with the Pahsimeroi River) in Idaho provided migration corridors and significant habitat for these ESA-listed species, in addition to the ESA-listed bull trout (Salvelinus confluentus). Human development has modified the original streamflow conditions in many streams in the upper Salmon River Basin. Summer streamflow modifications resulting from irrigation practices, have directly affected quantity and quality of fish habitat and also have affected migration and (or) access to suitable spawning and rearing habitat for these fish. As a result of these ESA listings and Action 149 of the Federal Columbia River Power System Biological Opinion of 2000, the Bureau of Reclamation was tasked to conduct streamflow characterization studies in the upper Salmon River Basin to clearly define habitat requirements for effective species management and habitat restoration. These studies include collection of habitat and streamflow information for the Physical Habitat Simulation System (PHABSIM) model, a widely applied method to determine relations between habitat and discharge requirements for various fish species and life stages. Model simulation results can be used by resource managers to guide habitat restoration efforts by evaluating potential fish habitat and passage improvements by increasing or decreasing streamflow. In 2005, instream flow characterization studies were completed on Big Boulder, Challis, Bear, Mill, and Morgan Creeks. Continuous streamflow data were recorded upstream of all diversions on Big Boulder. Instantaneous measurements of discharge were also made at selected sites. In

    he U.S. Geological Survey (USGS), in cooperation with Idaho Department of Environmental Quality, developed spreadsheet mass-balance models for total phosphorus using results from three synoptic sampling periods conducted in the lower Boise River watershed during August and October 2012, and March 2013. The modeling reach spanned 46.4 river miles (RM) along the Boise River from Veteran’s Memorial Parkway in Boise, Idaho (RM 50.2), to Parma, Idaho (RM 3.8). The USGS collected water-quality samples and measured streamflow at 14 main-stem Boise River sites, two Boise River north channel sites, two sites on the Snake River upstream and downstream of its confluence with the Boise River, and 17 tributary and return-flow sites. Additional samples were collected from treated effluent at six wastewater treatment plants and two fish hatcheries. The Idaho Department of Water Resources quantified diversion flows in the modeling reach. Total phosphorus mass-balance models were useful tools for evaluating sources of phosphorus in the Boise River during each sampling period. The timing of synoptic sampling allowed the USGS to evaluate phosphorus inputs to and outputs from the Boise River during irrigation season, shortly after irrigation ended, and soon before irrigation resumed. Results from the synoptic sampling periods showed important differences in surface-water and groundwater distribution and phosphorus loading. In late August 2012, substantial streamflow gains to the Boise River occurred from Middleton (RM 31.4) downstream to Parma (RM 3.8). Mass-balance model results indicated that point and nonpoint sources (including groundwater) contributed phosphorus loads to the Boise River during irrigation season. Groundwater exchange within the Boise River in October 2012 and March 2013 was not as considerable as that measured in August 2012. However, groundwater discharge to agricultural tributaries and drains during non-irrigation season was a large source of discharge and

    McLeod, J.D. )

    1993-08-01

    Between 1903 and 1988, approximately 145 wells were drilled to explore for commercial hydrocarbon deposits in Idaho. Although deep drilling has thus far failed to locate oil or gas reserves, a wealth of geological, geophysical, and geochemical data have been collected, and areas worthy of more exploration have been identified. The wells also have encountered potable groundwater, potential geothermal resources, evaporites, phosphate rock, and brine that may one day prove to be of economic significance. Most exploration has occurred in two geologic provinces: (1) the upper Tertiary sediments and interbedded volcanic rocks of ancient Lake Idaho that underlie the western Snake River Plain, and (2) the predominantly marine Paleozoic and Mesozoic sedimentary rocks in the thrust belt of southeast Idaho. Additional scattered deep tests have penetrated the eastern Snake River Plain, the Cassia and Beaverhead-Centennial mountain areas, the Idaho panhandle, and the eastern margin of the Columbia Plateau. Of all the regions explored, the northern part of the Idaho thrust belt beneath the Caribou Range appears most promising for future exploration. It is characterized by prominent surface anticlines, a thick stratigraphic section from Cambrian through fine-grained Cretaceous rocks, the potential for source and reservoir beds, and numerous oil and gas shows. In contrast to other areas of the Idaho thrust belt, deep formations also contain connate water, suggesting effective early sealing of prospective reservoir beds.

    The study of the Casto quadrangle was undertaken as the first item in a project to obtain more thorough knowledge of the general geology of southcentral Idaho on which to base study of the ore deposits of t he region. The quadrangle conta ins fragmentary exposures of Algonkian and Paleozoic sedimentary rocks, extensive deposits of old volcanic strata, presumably Permian, not heretofore recognized in this part of Idaho, and a thick succession of Oligocene(?) lava and pyroclastic rocks. The Idaho batholith and its satellites extend into the quadrangle, and in addition there a re large masses of Tertiary granitic rock, not previously distinguished in Idaho, and many Tertiary dikes, some of which are genetically associated with contact-metamorphic deposits. The area contains injection gneiss of complex origin, largely related to the Idaho batholith but in part resulting from injection by ~he Tertiary granitic rocks under relatively light load. Orogenic movement took place in Algonkian, Paleozoic, and Tertiary time. There is a summit peneplain or par tial peneplain of Tertiary, perhaps Pliocene age, and the erosional history since its elevation has been complex. The ore deposits include lodes and placers. The lodes are related to both the Idaho batholith and the Tert iary intrusive rocks and have yielded gold and copper ore of a total value of about 1,000,000. Placers, largely formed in an interglacial inter val, have yielded about an equal amount. There has been some prospecting but almost no production since 1916.

    It is the policy of the Department of Energy (DOE) that pollution prevention and sustainable environmental stewardship will be integrated into DOE operations as a good business practice to reduce environmental hazards, protect environmental resources, avoid pollution control costs, and improve operational efficiency and mission sustainability. In furtherance of this policy, DOE established five strategic, performance-based Pollution Prevention (P2) and Sustainable Environmental Stewardship goals and included them as an attachment to DOE O 450.1, Environmental Protection Program. These goals and accompanying strategies are to be implemented by DOE sites through the integration of Pollution Prevention into each site's Environmental Management System (EMS). This document presents a P2 and Sustainability Program and corresponding plan pursuant to DOE Order 450.1 and DOE O 435.1, Radioactive Waste Management. This plan is also required by the state of Idaho, pursuant to the Resource Conservation and Recovery Act (RCRA) partial permit. The objective of this document is to describe the Idaho National Laboratory (INL) Site P2 and Sustainability Program.

    2010-07-06

    This talk is about fishing and the friendships that have resulted in its pursuit. It is also about theoretical physics, and the relationship of imagination and fantasy to the establishment of ideas about nature. Fishermen, like theoretical physicists, are well known for their inventive imaginations. Perhaps neither are as clever as sailors, who conceived of the mermaid. If one doubts the power of this fantasy, one should remember the ghosts of the many sailors who drowned pursuing these young nymphs. An extraordinary painting by J. Waterhouse is shown as Fig. 1. The enchantment of a mermaid must reflect an extraordinary excess of imagination on the part of the sailor, perhaps together with an impractical turn of mind. A consummated relationship with a mermaid is after all, by its very nature a fantasy incapable of realization. To a theoretical physicist, she is symbolic of many ideas we develop. There are many truths known to fisherman in which one might also find parallels to the goals of scientists: (1) A fish is the only animal that keeps growing after its death; (2) Nothing makes a fish bigger than almost being caught; (3) ''...of all the liars among mankind, the fisherman is the most trustworthy.'' (William Sherwood Fox, in Silken Lines and Silver Hooks); and (4) Men and fish are alike. They both get into trouble when they open their mouths. These quotes may be interpreted as reflecting skepticism regarding the honesty of fisherman, and probably do not reflect adequate admiration for a creative imagination. Is it fair to criticize a person for believing a falsehood that he or she sincerely believes to be true? The fisherman simultaneously invents the lie, and believes in it himself. The parallel with theoretical physics is perhaps only approximate, although we physicists may invent stories that we come to believe, on some rare occasions our ideas actually correspond to a more or less true descriptions of nature. These minor philosophical differences are not

    Sampling for radionuclides in groundwater was conducted at the Idaho National Engineering Laboratory during September to November 5 1987. Water samples from 80 wells that obtain water from the Snake River Plain aquifer and 1 well that obtains water from a shallow, discontinuous perched-water body at the Radioactive Waste Management Complex were collected and analyzed for tritium, strontium-90, plutonium-238, plutonium-239, -240 (undivided), americium-241, cesium-137, cobalt-60, and potassium-40--a naturally occurring radionuclide. The groundwater samples were analyzed at the Idaho National Engineering Laboratory in Idaho. Tritium and strontium-90 concentrations ranged from below the reporting level to 80.6 +/-0.000005 and 193 +/-5x10 to the minus eight micrograms Ci/ml, respectively. Water from a disposal well at Test Area North--which has not been used to dispose of waste water since September 1972--contained 122 +/-9x10 to the minus eleven micrograms Ci/ml of plutonium-238, 500 +/-20x10 to the minus eleven of plutonium-239, -240 (undivided), 21 +/-4x10 to the minus eleven micrograms Ci/ml of americium-241, and 750 +/-20x10 to the minus eight micrograms Ci/ml cesium-137; the presence of these radionuclides was verified by resampling and reanalysis. The disposal well had 8.9 +/-0.0000009 micrograms Ci/ml of cobalt-60 on October 28, 1987, but cobalt-60 was not detected when the well was resampled on January 11, 1988. Potassium-40 concentrations were less than the reporting level in all wells. (USGS)

    The Kootenai Tribe of Idaho, in cooperation with local, State, Federal, and Canadian agency co-managers and scientists, is assessing the feasibility of a Kootenai River habitat restoration project in Boundary County, Idaho. This project is oriented toward recovery of the endangered Kootenai River white sturgeon (Acipenser transmontanus) population, and simultaneously targets habitat-based recovery of other native river biota. Projects currently (2010) under consideration include modifying the channel and flood plain, installing in-stream structures, and creating wetlands to improve the physical and biological functions of the ecosystem. River restoration is a complex undertaking that requires a thorough understanding of the river. To assist in evaluating the feasibility of this endeavor, the U.S. Geological Survey collected and analyzed the physical and chemical nature of sediment cores collected at 24 locations in the river. Core depths ranged from 4.6 to 15.2 meters; 21 cores reached a depth of 15.2 meters. The sediment was screened for the presence of chemical constituents that could have harmful effects if released during restoration activities.

    2000-01-01

    Recent decline of Pacific lamprey Lampetra tridentata adult migrants to the Snake River drainage has focused attention on the species. Adult returns in 1995-1999 were more than ten magnitudes less than returns in the early 1960's. Human activities in the Snake River and Clearwater River drainages have altered ecosystem habitat in the last 100 years and likely the productive potential of Pacific lamprey habitat. Logging, stream impoundment, road construction, grazing, mining, and community development have dominated habitat alteration in the Clearwater River system and Snake River corridor. Hydroelectric projects in the Snake River corridor impact juvenile Pacific lamprey outmigrants and returning adults. Juvenile lamprey outmigrants potentially pass through turbines, turbine bypass and collection systems, and spillway structures at lower Snake River hydroelectric dams. Clearwater River drainage hydroelectric facilities including the Pacific Power and Light Dam on the Clearwater River in Lewiston, Idaho, impacted Pacific lamprey populations, however, the degree of impact is unknown (1920's-early 1970's). Hydroelectric dam construction (Harpster Dam) on the South Fork of the Clearwater River resulted in obstructed salmonid passage in the mid-1900's. Habitat alterations in the Snake River basin and Clearwater River drainage have had numerous negative effects on salmon Oncorhynchus spp. and steelhead trout O. mykiss populations (wild fish), but the magnitude of impacts on lamprey productivity and survival is unknown. Thorough understanding of Pacific lamprey habitat use and life history processes is needed to facilitate management and restoration of the species. Through Bonneville Power Administration support, the Idaho Department of Fish and Game began investigation into the status of Pacific lamprey populations in Idaho's Clearwater River drainage in 2000. Trapping, electrofishing, and spawning ground redd surveys were used to determine where Pacific lamprey persist

    Recent decline of Pacific lamprey Lampetra tridentata adult migrants to the Snake River drainage has focused attention on the species. Adult Pacific lamprey counted passing Ice Harbor Dam fishway averaged 18,158 during 1962-69 and 361 during 1993-2000. Human resource manipulations in the Snake River and Clearwater River drainages have altered ecosystem habitat in the last 120 years, likely impacting the productive potential of Pacific lamprey habitat. Timber harvest, stream impoundment, road construction, grazing, mining, and community development have dominated habitat alteration in the Clearwater River system and Snake River corridor. Hydroelectric projects in the Snake River corridor impact juvenile/larval Pacific lamprey outmigrants and returning adults. Juvenile and larval lamprey outmigrants potentially pass through turbines, turbine bypass/collection systems, and over spillway structures at the four lower Snake River hydroelectric dams. Clearwater River drainage hydroelectric facilities have impacted Pacific lamprey populations to an unknown degree. The Pacific Power and Light Dam on the Clearwater River in Lewiston, Idaho, restricted chinook salmon Oncorhynchus tshawytscha passage in the 1927-1940 period, altering the migration route of outmigrating Pacific lamprey juveniles/larvae and upstream adult migrants (1927-1972). Dworshak Dam, completed in 1972, eliminated Pacific lamprey spawning and rearing in the North Fork Clearwater River drainage. Construction of the Harpster hydroelectric dam on the South Fork of the Clearwater River resulted in obstructed fish passage 1949-1963. Through Bonneville Power Administration support, the Idaho Department of Fish and Game continued investigation into the status of Pacific lamprey populations in Idaho's Clearwater River drainage in 2001. Trapping, electrofishing, and spawning ground redd surveys were used to determine Pacific lamprey distribution, life history strategies, and habitat requirements in the South Fork

    This document has been prepared by the Department of Energy`s (DOE) Environmental Management (EM) Office of Technology Development (OTD) in order to highlight research, development, demonstration, testing, and evaluation (RDDT&E) activities funded through the Idaho Operations Office. Technologies and processes described have the potential to enhance DOE`s cleanup and waste management efforts, as well as improve US industry`s competitiveness in global environmental markets. OTD programs are designed to make new, innovative, and more cost-effective technologies available for transfer to DOE environmental restoration and waste management end-users. Projects are demonstrated, tested, and evaluated to produce solutions to current problems. Transition of technologies into more advanced stages of development is based upon technological, regulatory, economic, and institutional criteria. New technologies are made available for use in eliminating radioactive, hazardous, and other wastes in compliance with regulatory mandates. The primary goal is to protect human health and prevent further contamination. OTD`s technology development programs address three major problem areas: (1) groundwater and soils cleanup; (2) waste retrieval and processing; and (3) pollution prevention. These problems are not unique to DOE, but are associated with other Federal agency and industry sites as well. Thus, technical solutions developed within OTD programs will benefit DOE, and should have direct applications in outside markets.

    1985-01-01

    The Sawtooth batholith is one of several anorogenic granite plutons in Central Idaho. These epizonal plutons, emplaced during the Challis volcanic-plutonic event, are for the most part associated with cauldera complexes of Tertiary age. Miarolitic cavities and small pegmatite dikes in the Sawtooth batholith contain a suite of uncommon minerals. The more common minerals of this suite are quartz (commonly smoky), microcline, albite, fluorite, hematite, topaz, and beryl (variety aquamarine). In addition a less common suite of Mn-rich minerals is found. These include helvite, spessartine garnet, zinnwaldite-masutomilite series micas, and a Mn-K-Li-rich member of the carpholite group. Of these rarer minerals the most interesting are the carpholite group member and the micas. The K occupies a crystallographic site which is normally vacant in carpholite group minerals and can have a maximum occupancy of 1. This mineral most likely represents a new species in the carpholite group. The zinnwaldite-masutomilite micas are rather low in Li and have Fe:Mn ratios ranging from about 2.2 to 0.5. These Li contents are typical of zinnwaldites from anorogenic granite pegmatites. However, all other reported occurrences of masutomilite have been richer in Li.

    There is explicit need for characterization of the materials for possible commercialization as little characterization data exists. Pinyon-juniper woodlands are a major ecosystem type found in the Southwest and the Intermountain West regions of the United States including Nevada, Idaho and Oregon. These widespread ecosystems are characterized by the presence of several different species of pinyon and juniper as the dominant plant cover. Since the 1800s, pinyon-juniper woodlands have rapidly expanded their range at the expense of existing ecosystems. Additionally, existing woodlands have become denser, progressively creating potential fire hazards as seen in the Soda Fire, which burned more than 400 sq. miles. Land managers responsible for these areas often desire to reduce pinyon-juniper coverage on their lands for a variety of reasons, as stated in the Working Group objectives. However, the cost of clearing thinning pinyon-juniper stands can be prohibitive. One reason for this is the lack of utilization options for the resulting biomass that could help recover some of the cost of pinyon-juniper stand management. The goal of this TAP effort was to assess the feedstock characteristics of biomass from a juniper harvested from Owyhee County to evaluate possible fuel and conversion utilization options.

    1980-01-01

    Fifty-four pronghorn (Antilocapra americana) were radio-collared out of 232 captured on 3 winter ranges in southeastern Idaho. Radioed pronghorn were followed for up to 21 months each, from December 1975 through August 1977. Winter home ranges showed a difference (P < 0.005) in size among valleys the 1st winter and were different in size and location within valleys between years. Snow covered the ground 1 week earlier and lasted 3 weeks longer in 1975 to 1976 than in 1976 to 1977. Spring migration began more than 1 month earlier in 1977 than 1976, and appeared related to loss of snow cover on the winter ranges in both years. Distances that pronghorn migrated in spring 1976 were different among valleys (P < 0.05) but directions were, in general, upward to areas near the heads of the valleys. Summer home ranges of all radioed pronghorn averaged 2033 +- 322 (SE) ha. Yearlings wandered during summer and their home ranges were 2 to 5 times as large as ranges of adults. Fall migration in 1976 began after 1 October and was not prompted by snowfall. Percent moisture in vegetation is suggested as a stimulus for onset of fall migration, and snowfall is suggested as a factor influencing distance migrated and location of winter.

    Phosphate ores contain elevated levels of natural radioactivity, some of which is released to the environment during processing or use of solid byproducts. The effect of radionuclides from Idaho phosphate processing operations on the local communities has been the subject of much research and study. The literature is reviewed in this report. Two primary radionuclide pathways to the environment have been studied in detail: (1) airborne release of volatile radionuclides, primarily /sup 210/Po, from calciner stacks at the two elemental phosphorus plants; and (2) use of byproduct slag as an aggregate for construction in Soda Springs and Pocatello. Despite the research, there is still no clear understanding of the population dose from radionuclide emissions, effluents, and solid wastes from phosphate processing plants. Two other potential radionuclide pathways to the environment have been identified: radon exhalation from phosphogypsum and ore piles and contamination of surface and ground waters. Recommendations on further study needed to develop a data base for a complete risk assssment are given in the report.

  11. A mycosis-like granuloma of fish

    Mycoses of systemic distribution are rarely observed in fresh-water fish in this country. In a recent review of atypical cell growths in fishes, Nigrelli cited the only known instance of a mycetoma in a North American fresh-water fish which occurred in the head of fingerling landlocked salmon from an Idaho hatchery. The fungus associated with this granuloma was characterized by a branching septate mycelium. Rucker reported a streptomycete which was pathogenic to blueblack salmon. This organism produced internal nodules containing masses of hyphae but no inflammatory response. A pathogenic fungus has been observed frequently in marine fish, however, and in both marine and fresh-water fish in Europe. This organism was tentatively classified as a Phycomycete in or near the order Chytridiales and was assigned to the genus and species Ichthyophonus hoferi, later reclassified as Ichthyosporidium hoferi. The graduloma described in this report occurs in fresh-water trout and is apparently caused by a budding, yeast-like form with no hyphae which evokes a tremendous inflammatory reaction. Morphologically, the organism does not resemble the previously described Ichthyosporidium. The lesions were first seen accidentally in sections prepared from a diplobacillus infection of brook trout termed “kidney disease.” Subsequently, the granuloma was observed in three widely separated infections involving the diplobacillus in each instance.The histological material was received in a fixed condition; thus, no cultural data was available and the nomenclature and classification of the mycotic organism were not attempted. The present distribution of the disease, however, with its potential threat to domestic fish populations, seemed to warrant a description and discussion of the disease. Efforts are in progress to culture the organism.

    Aqueous chemical and radioactive wastes have been discharged to shallow ponds and to shallow or deep wells on the Idaho National Engineering Laboratory (INEL) since 1952 and has affected the quality of the ground water in the underlying Snake River Plain aquifer. Ongoing studies conducted from 1974 through 1978 have shown the perpetuation of a perched ground-water zone in the basalt underlying the waste disposal ponds at the INEL 's Test Reactor Area and of several waste plumes in the regional aquifer created by deep well disposal at the Idaho Chemical Processing Plant (ICPP). The perched zone contains tritium, chromium-51, cobalt-60, strontium-90, and several nonradioactive chemicals. Tritium has formed the largest waste plume south of the ICPP, and accounts for 95 percent of the total radioacticity disposed of through the ICPP disposal well. Waste plumes with similar configurations and flowpaths contain sodium, chloride, and nitrate. Strontium-90, iodine-129, and cesium-137 are also discharged through the well but they are sorbed from solution as they move through the aquifer or are discharged in very small quantities. Strontium-90 and iodine-129 have formed small waste plumes and cesium-137 is not detectable in ground-water samples. Radionuclide plume size and concentrations therein are controlled by aquifer flow conditions, the quantity discharged, radioactive decay, sorption, dilution by dispersion, and perhaps other chemical reactions. Chemical wastes are subject to the same processes except for radioactive decay. (USGS)

    Strontium distribution coefficients (Kd's) were measured for 24 basalt core samples collected from selected sites at the Idaho National Engineering and Environmental Laboratory (INEEL). The measurements were made to help assess the variability of strontium Kd's as part of an ongoing investigation of strontium transport properties through geologic materials at the INEEL. The investigation is being conducted by the U.S. Geological Survey and Idaho State University in cooperation with the U.S. Department of Energy. Batch experiments were used to measure Kd's of basalt core samples using an aqueous solution representative of wastewater in waste-disposal ponds at the INEEL. Calculated strontium Kd's of the 24 basalt core samples ranged from 3.6{+-}1.3 to 29.4{+-}1.6 milliliters per gram. These results indicate a narrow range of variability in the strontium sorptive capacities of basalt relative to those of the sedimentary materials at the INEEL. The narrow range of the basalt Kd's can be attributed to physical and chemical properties of the basalt, and to compositional changes in the equilibrated solutions after being mixed with the basalt. The small Kd's indicate that basalt is not a major contributor in preventing the movement of strontium-90 in solution.

  15. Subsurface information from eight wells drilled at the Idaho National Engineering Laboratory, southeastern Idaho

    1982-01-01

    The Idaho National Engineering Laboratory (INEL) covers about 890 square miles of the eastern Snake River Plain, in southeastern Idaho. The eastern Snake River Plain is a structural basin which has been filled with thin basaltic lava flows, rhyolitic deposits, and interbedded sediments. These rocks form an extensive ground-water reservoir known as the Snake River Plain aquifer. Six wells were drilled and two existing wells were deepened at the INEL from 1969 through 1974. Interpretation of data from the drilling program confirms that the subsurface is dominated by basalt flows interbedded with layers of sediment, cinders, and silicic volcanic rocks. Water levels in the wells show cyclic seasonal fluctuations of maximum water levels in winter and minimum water levels in mid-summer. Water levels in three wells near the Big Lost River respond to changes in recharge to the Snake River Plain aquifer from the Big Lost River. Measured water levels in multiple piezometers in one well indicate increasing pressure heads with depth. A marked decline in water levels in the wells since 1977 is attributed to a lack of recharge to the Snake River Plain aquifer.

    Underwater time-lapse video technology was used to monitor adult spring and summer chinook salmon abundance in spawning areas in Lake Creek and the Secesh River, Idaho, in 1999. This technique is a passive methodology that does not trap or handle this Endangered Species Act listed species. This was the third year of testing the remote application of this methodology in the Secesh River drainage. Secesh River chinook salmon represent a wild salmon spawning aggregate that has not been directly supplemented with hatchery fish. Adult chinook salmon spawner abundance was estimated in Lake Creek with the remote time-lapse video application. Adult spawner escapement into Lake Creek in 1999 was 67 salmon. Significant upstream and downstream spawner movement affected the ability to determine the number of fish that contributed to the spawning population. The first passage on Lake Creek was recorded on July 11, two days after installation of the fish counting station. Peak net upstream adult movement occurred at the Lake Creek site on July 20, peak of total movement activity was August 19 with the last fish observed on August 26. A minimum of 133 adult chinook salmon migrated upstream past the Secesh River fish counting station to spawning areas in the Secesh River drainage. The first upstream migrating adult chinook salmon passed the Secesh River site prior to the July 15 installation of the fish counting station. Peak net upstream adult movement at the Secesh River site occurred July 19, peak of total movement was August 15, 17 and 18 and the last fish passed on September 10. Migrating salmon in the Secesh River and Lake Creek exhibited two behaviorally distinct segments of fish movement. Mainly upstream only, movement characterized the first segment. The second segment consisted of upstream and downstream movement with very little net upstream movement. Estimated abundance was compared to single and multiple-pass redd count surveys within the drainage. There were

    Forage fish support the largest fisheries in the world but also play key roles in marine food webs by transferring energy from plankton to upper trophic-level predators, such as large fish, seabirds, and marine mammals. Fishing can, thereby, have far reaching consequences on marine food webs unless safeguards are in place to avoid depleting forage fish to dangerously low levels, where dependent predators are most vulnerable. However, disentangling the contributions of fishing vs. natural processes on population dynamics has been difficult because of the sensitivity of these stocks to environmental conditions. Here, we overcome this difficulty by collating population time series for forage fish populations that account for nearly two-thirds of global catch of forage fish to identify the fingerprint of fisheries on their population dynamics. Forage fish population collapses shared a set of common and unique characteristics: high fishing pressure for several years before collapse, a sharp drop in natural population productivity, and a lagged response to reduce fishing pressure. Lagged response to natural productivity declines can sharply amplify the magnitude of naturally occurring population fluctuations. Finally, we show that the magnitude and frequency of collapses are greater than expected from natural productivity characteristics and therefore, likely attributed to fishing. The durations of collapses, however, were not different from those expected based on natural productivity shifts. A risk-based management scheme that reduces fishing when populations become scarce would protect forage fish and their predators from collapse with little effect on long-term average catches.

  4. Testing Phoenix Mars Lander Parachute in Idaho

    NASA Technical Reports Server (NTRS)

    2008-01-01

    NASA's Phoenix Mars Lander will parachute for nearly three minutes as it descends through the Martian atmosphere on May 25, 2008. Extensive preparations for that crucial period included this drop test near Boise, Idaho, in October 2006.

    The parachute used for the Phoenix mission is similar to ones used by NASA's Viking landers in 1976. It is a 'disk-gap-band' type of parachute, referring to two fabric components -- a central disk and a cylindrical band -- separated by a gap.

    Although the Phoenix parachute has a smaller diameter (11.8 meters or 39 feet) than the parachute for the 2007 Mars Pathfinder landing (12.7 meters or 42 feet), its Viking configuration results in slightly larger drag area. The smaller physical size allows for a stronger system because, given the same mass and volume restrictions, a smaller parachute can be built using higher strength components. The Phoenix parachute is approximately 1.5 times stronger than Pathfinder's. Testing shows that it is nearly two times stronger than the maximum opening force expected during its use at Mars.

    Engineers used a dart-like weight for the drop testing in Idaho. On the Phoenix spacecraft, the parachute is attached the the backshell. The backshell is the upper portion of a capsule around the lander during the flight from Earth to Mars and protects Phoenix during the initial portion of the descent through Mars' atmosphere.

    Phoenix will deploy its parachute at about 12.6 kilometers (7.8 miles) in altitude and at a velocity of 1.7 times the speed of sound. A mortar on the spacecraft fires to deploy the parachute, propelling it away from the backshell into the supersonic flow. The mortar design for Phoenix is essentially the same as Pathfinder's. The parachute and mortar are collectively called the 'parachute decelerator system.' Pioneer Aerospace, South Windsor, Conn., produced this system for Phoenix. The same company provided the parachute decelerator systems for Pathfinder, Mars Polar

    Rockland basin comprises about 320 sq mi of the Snake River drainage in southeastern Idaho. Mountain ranges bordering the basin are composed predominantly of limestone and are complexly faulted. Major aquifers include Holocene alluvium, Quaternary-Tertiary volcanic rocks, and Tertiary sedimentary rocks. Groundwater occurs under water table conditions except where it is locally confined. Groundwater discharges to springs in the Deep Creek Mountains and maintains perennial streamflow. Near the mouth of Rock Creek, groundwater movement is northward toward the Snake River. Underflow is estimated to be 51,000 acre-ft/yr. Total water yield available to Rockland basin is estimated to be 5.0 in. (85,000 acre-ft) of the estimated 17.3 in. of annual precipitation. Evapotranspiration ranges from 9.9 to 17 in./yr, depending, in part, on altitude of the land surface. An estimated 12,000 acre-ft of surface water and 3,500 acre-ft of groundwater are used annually for irrigation. Less than 100 acre-ft of water is used for public supply, domestic, and stock supplies. East Fork Rock Creek supplies the most surface water for irrigation of agricultural lands. At the present (1980) state of groundwater development in Rockland basin, streams and aquifers are hydraulically connected. Pumping of groundwater in increased quantities from wells near streams will affect groundwater movement and may diminish streamflow. There are no long-term regional water table declines at present. Continued water level monitoring of selected wells may aid in documenting effects of future management practices on the groundwater system. (Author 's abstract)

  7. Selective removal of ATP degradation products from food matrices II: Rapid screening of hypoxanthine and inosine by molecularly imprinted matrix solid-phase dispersion for evaluation of fish freshness.

    A water compatible molecularly imprinted polymer (MIP), synthesized using theophylline (TPH) as dummy-template and acrylamide (AM) as functional monomer, has been employed as supporting material in matrix solid-phase dispersion combined with ultra performance liquid chromatography-photodiode array detection (MSPD-UPLC-PDA) for selective determination of adenosine triphosphate (ATP) derivatives in fish samples. ATP degradation products are used as freshness index for assessment of fish quality. The solid sample was directly blended with MIP in MSPD procedure resulting in sample disruption and subsequent adsorption of the compounds on the MIP. By using n-hexane and ammonium hydroxide aqueous solution at pH 9 as the washing and elution solvent, respectively, satisfactory recoveries and clean chromatograms have been obtained. Good linearity for hypoxanthine (HYP) and inosine (INO) has been observed with correlation coefficients (R(2)) of 0.9987 and 0.9986, respectively. The recoveries of the two ATP derivatives at three different spiked levels ranged from 106.5% to 113.4% for HYP and from 103.1% to 111.2% for INO, with average relative standard deviations lower than 4.2% in both cases. This new method, which is rapid, simple and sensitive, can be used as an alternative tool to conventional tedious methods. PMID:25640126

    Benthic macroinvertebrates with elevated concentrations of metals were collected from the Coeur d'Alene (CDA) River, Idaho, pasteurized, and fed to cutthroat trout Oncorhynchus clarki in the laboratory from start of feeding until 90 d posthatch. Invertebrates were collected from two sites known to contain elevated concentrations of metals: near Pinehurst in the South Fork of the CDA River and at Cataldo, approximately 5 km below the confluence of the South Fork and the North Fork. Invertebrates collected from a relatively clean site in the North Fork were used as a reference diet. We performed measurements of fish health that indicate reduced fitness of fish fed the South Fork and Cataldo diets. Effects measured were reduced feeding activity, increased number of macrophage aggregates and hyperplasia of cells in the kidney, degeneration of mucosal epithelium in the pyloric caecae, and metallothionein induction. These effects would likely reduce growth and survival of fish in the wild. Vacuolization of glial cells were also observed in fish fed the Cataldo diet. Metals in the water often exacerbated the histological effects observed. Although the invertebrates collected near Cataldo had lower concentrations of arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn) than the invertebrates from the South Fork, fish fed the Cataldo diet had equally high or higher concentrations of all metals except as by day 44. The Cataldo diet also caused the most deleterious effects on survival and growth. These findings are especially important for early life stage fish, whose diet consists wholly of benthic macroinvertebrates. Therefore, fish feeding on invertebrates in the CDA River below the Bunker Hill smelting complex are at risk of reduced fitness.

    The etiologic agent for the bacterial disease, "fish tuberculosis" (more correctly "mycobacteriosis"), was first observed in carp in 189& from a pond in France. Subsequently similar agents have been isolated from or observed in fish in fresh water, salt water, and brackish water, in fish in aquaria, hatcheries, and natural habitat~ (wild populations of fish). The disease has been recognized as an important infection among hatchery reared salmonid fishes on the West Coast of the United States, and in aquarium fishes such as the neon tetra, the Siamese fighting fish, and in salt water fish held in zoological displays.

    The Tennessee Valley Authority (TVA) operates 9 reservoirs on the Tennessee River and 37 reservoirs on its tributaries. TVA is committed to maintaining the health of aquatic resources created when the reservoir system was built. To that end, TVA in cooperation with Valley states, operates a water resource monitoring program that includes physical, chemical, and biological data collection components. Biological monitoring will target the following selected elements within three zones of the reservoir (inflow, transition, and forebay): Sediment/Water-column Acute Toxicity Screening, Benthic macroinvertebrates, and Fish. Reservoir fisheries monitoring is divided into the following activities: Fish Biomass, Fish Tissue Contamination, Fish Community Monitoring, and Fish Health Assessment. This report presents the results of fish community monitoring and fish health assessments.

    The Bonneville Power Administration (BPA) initiated the Augmented Fish Health Monitoring project in 1986. This project was a five year interagency project involving fish rearing agencies in the Columbia Basin. Historically, all agencies involved with fish health in the Columbia Basin were conducting various levels of fish health monitoring, pathogen screening and collection. The goals of this project were; to identify, develop and implement a standardized level of fish health methodologies, develop a common data collection and reporting format in the area of artificial production, evaluate and monitor water quality, improve communications between agencies and provide annual evaluation of fish health information for production of healthier smolts. This completion report will contain a project evaluation, review of the goals of the project, evaluation of the specific fish health analyses, an overview of highlights of the project and concluding remarks. 8 refs., 1 fig., 4 tabs.

    Project 83-7 was established under the Northeast Power Planning Council's 1982 Fish and Wildlife Program, Measure 704 (d) (1) to monitor natural production of anadromous fish, evaluate Bonneville Power Administration habitat improvement project, and develop a credit record for off-site mitigation projects in Idaho. Project 83-7 is divided into two sub-projects: general and intensive monitoring. Results of the intensive monitoring sub-project are reported here. Results from the general monitoring sub-project will be reported in a separate document. The purpose of this intensive monitoring project is to determine the number of returning chinook and steelhead adults necessary to achieve optimal smolt production, and develop mitigation accounting based on increases in smolt production. Two locations are being intensively studied to meet these objectives. Information from this research will be applied to parr monitoring streams statewide to develop escapement objectives and determine success of habitat enhancement projects. Field work began in 1987 in upper Salmon River and Crooked River (South Fork Clearwater River tributary). Methods include using weirs to trap adults, conducting ground and aerial redd counts, snorkeling to estimate parr populations, PIT-tagging juveniles to determine parr-tosmolt survival, trapping fall and spring downstream emigrants with scoop traps, and outplanting adults to determine juvenile carrying capacity. PIT tags also provide a wide range of other information such as migration timing, effects of flow and passage conditions on smolt survival, other factors affecting smolt survival, and growth.

    In 1975, 3.2 km of Summit Creek, Idaho were fenced by the Bureau of Land Management to exclude livestock from the riparian area. Six stream sections were electrofished in 1979 to determine differences in trout abundance, size, and growth between grazed and ungrazed stream sections. Electrofishing stations were paired by habitat type. There were more trout in ungrazed sections than in grazed sections in all three habitat types sampled. With one exception, there were more catachable-sized (200 mm long or longer) rainbow trout (Salmo gairdneri) and brook trout (Salvelinus fontinalis) in the ungrazed area than in the grazed area. There was also evidence that the average size of the fish was less in grazed sections. Fish population data were not collected prior to fencing; therefore, it cannot be firmly concluded that the trout population increased within the livestock enclosure as a result of fencing the riparian area. However, the combined results of previous trout habitat improvements documented for Summit Creek, as a result of the fencing, and this study support the conclusion that trout prefer stream areas in ungrazed habitat over grazed habitat.

    The Visi Screen OSS-C, marketed by Vision Research Corporation, incorporates image processing technology originally developed by Marshall Space Flight Center. Its advantage in eye screening is speed. Because it requires no response from a subject, it can be used to detect eye problems in very young children. An electronic flash from a 35 millimeter camera sends light into a child's eyes, which is reflected back to the camera lens. The photorefractor then analyzes the retinal reflexes generated and produces an image of the child's eyes, which enables a trained observer to identify any defects. The device is used by pediatricians, day care centers and civic organizations that concentrate on children with special needs.

    Southeastern Idaho exhibits numerous warm springs, warm water from shallow wells, and hot water from oil and gas test wells that indicate a potential for geothermal development in the area. We have estimated reservoir temperatures from chemical composition of thermal waters in southeastern Idaho using an inverse geochemical modeling technique (Reservoir Temperature Estimator, RTEst) that calculates the temperature at which multiple minerals are simultaneously at equilibrium while explicitly accounting for the possible loss of volatile constituents (e.g., CO2), boiling and/or water mixing. The temperature estimates in the region varied from moderately warm (59 °C) to over 175 °C. Specifically, hot springs near Preston, Idaho, resulted in the highest reservoir temperature estimates in the region.

    Rodney Hunt Co. shipped two 30-foot by 28-foot fabricated steel roller gates to Idaho Power Co.'s Swan Falls Dam Project, where they will be installed as draft tube gates. Rodney Hunt said the gates, each weighing approximately 55 tons, are the largest roller gates the company has manufactured. The company supplied the gates under the terms of a contract worth more than $500,000. The gates were ordered as part of Idaho Power's rehabilitation of Swan Falls Dam, which will double the power plant's capacity to 25 MW. New units will begin producing power in 1993, and the project will be completed in 1994. Elsewhere on the Snake River, Idaho Power intends to increase the capacity of its Twin Falls project to 52 MW from 10 MW. Construction is scheduled to start in June 1993.

    Those phosphate related and food processing industries in Southeastern Idaho are identified which require large energy inputs and the potential for direct application of geothermal energy is assessed. The total energy demand is given along with that fractional demand that can be satisfied by a geothermal source of known temperature. The potential for geothermal resource development is analyzed by examining the location of known thermal springs and wells, the location of state and federal geothermal exploration leases, and the location of federal and state oil and gas leasing activity in Southeast Idaho. Information is also presented regarding the location of geothermal, oil, and gas exploration wells in Southeast Idaho. The location of state and federal phosphate mining leases is also presented. This information is presented in table and map formats to show the proximity of exploration and development activities to current food and phosphate processing facilities and phosphate mining activities.

  6. Influences of body size and environmental factors on autumn downstream migration of bull trout in the Boise River, Idaho

    Many fishes migrate extensively through stream networks, yet patterns are commonly described only in terms of the origin and destination of migration (e.g., between natal and feeding habitats). To better understand patterns of migration in bull trout,Salvelinus confluentus we studied the influences of body size (total length [TL]) and environmental factors (stream temperature and discharge) on migrations in the Boise River basin, Idaho. During the autumns of 2001-2003, we tracked the downstream migrations of 174 radio-tagged bull trout ranging in size from 21 to 73 cm TL. The results indicated that large bull trout (>30 cm) were more likely than small fish to migrate rapidly downstream after spawning in headwater streams in early autumn. Large bull trout also had a higher probability of arriving at the current terminus of migration in the system, Arrowrock Reservoir. The rate of migration by small bull trout was more variable and individuals were less likely to move into Arrowrock Reservoir. The rate of downstream migration by all fish was slower when stream discharge was greater. Temperature was not associated with the rate of migration. These findings indicate that fish size and environmentally related changes in behavior have important influences on patterns of migration. In a broader context, these results and other recent work suggest, at least in some cases, that commonly used classifications of migratory behavior may not accurately reflect the full range of behaviors and variability among individuals (or life stages) and environmental conditions. ??

    1988-01-01

    From 1953 to 1983, an estimated 0.01 to 0.136 Ci (curies)/year of iodine-129 were contained in wastewater generated by the ICPP (Idaho Chemical Processing Plant) at the Idaho National Engineering Laboratory. The wastewater was directly discharged to the Snake River Plain aquifer through a deep disposal well until February 9, 1984, when the well was replaced by an unlined infiltration pond; a second pond was put into use on October 17, 1985. For 1984-86, the annual amount of iodine-129 in wastewater discharged to the ponds ranged from 0.0064 to 0.039 Ci. In August 1986, iodine-129 concentrations in water from 35 wells near the ICPP ranged from less than the reporting level to 3.6 +or-0.4 pCi/L (picocuries/L). By comparison, in April 1977 the water from 20 wells contained a maximum of 27 +or-1 pCi/L of iodine-129; in 1981, the maximum concentration in water from 32 wells was 41 +or-2 pCi/L. The average concentrations of iodine-129 in water from 18 wells that were sampled in 1977, 1981 and 1986 were 4.0, 6.7 and 1.3 pCi/L, respectively. The marked decrease in the iodine-129 concentration from 1981 to 1986 is the result of three factors: (1) The amount of iodine-129 disposed annually; (2) a change from the routine use of the disposal well to the infiltration ponds; and (3) a dilution of the iodine-129 in the aquifer by recharge from the Big Lost River.

    1992-02-01

    The purpose of this report is to develop an engineering design package to protect the Federal Emergency Management Agency (FEMA) National Radio System (FNARS) facilities from the effects of high- altitude electromagnetic pulses (HEMPs). This report was developed specifically for the Idaho State Emergency Operating Center (EOC) in Boise, Idaho. It is highly probable that there will be a heavy dependence upon high-frequency (hf) radio communications for long- haul communications following a nuclear attack on the continental United States, should one occur. To maintain the viability of the FEMA hf radio network during such a situation, steps must be taken to protect the FNARS facilities against the effects of HEMP that are likely to be created in a nuclear confrontation. The solution must than be to reduce HEMP-induced stresses on the system by means of tailored retrofit hardening measures using commercial protection devices when available. It is the intent of this report to define the particular hardening measures that will minimize the susceptibility of system components to HEMP effects. To the extent economically viable, protective actions have been recommended for implementation, along with necessary changes or additions, during the period of the FNARS upgrade program. This report addresses electromagnetic pulse (EMP) effects only and disregards any condition in which radiation effects may be a factor. It has been established that, except for the source region of a surface burst, EMP effects of high-altitude bursts are more severe than comparable detonations in either air or surface regions. Any system hardened to withstand the more extreme EMP environment will survive the less severe EMP conditions. The threatening environment will therefore be limited to HEMP situations.

    1989-01-01

    A complex sequence of layered basalt flows, cinders, and sediment underlies the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory in southeastern Idaho. Wells drilled to 700 ft penetrate a sequence of 10 basalt-flow groups and 7 major sedimentary interbeds that range in age from about 100,000 to 600,000 years old. The 10 flow groups consist of 22 separate lava flows and flow-units. Each flow group is made up of from one to five petrographically similar flows that erupted from common source areas during periods of less than 200 years. Sedimentary interbeds consist of fluvial, lacustrine, and wind-blown deposits of clay, silt, sand, and gravel that accumulated during periods of volcanic inactivity ranging from thousands to hundreds of thousands of years. Flows and sediment are unsaturated to a depth of about 600 ft. Flows and sediment below a depth of 600 ft are saturated and make up the uppermost part of the Snake River Plain aquifer. The areal extent of flow groups and interbeds was determined from well cuttings, cores, geophysical logs, potassium-argon ages, and geomagnetic properties. Stratigraphical control was provided by four sequential basalt flows near the base of the unsaturated zone that have reversed geomagnetic polarity and high emission of natural gamma radiation compared to other flows. Natural gamma logs were used as a primary correlation tool. Natural-gamma emissions, which are generally uniform in related, petrographically similar flows, increase or decrease between petrographically dissimilar flows of different age and source. (USGS)

    In 2001, the intentional release of anthrax spores in the eastern United States increased concern about exposure to anthrax nationwide, and residents of Idaho sought assistance. Response from state and local agencies was required, increasing the strain on epidemiologists, laboratorians, and communications personnel. In late 2001, Idaho's public health communications system handled 133 calls about suspicious powders. For each call, a multiagency bridge call was established, and participants (public health officials, epidemiologists, police, Federal Bureau of Investigation personnel, hazardous materials officials, and others) determined which samples would be tested by the state public health laboratory. A triage system for calls helped relieve the burden on public safety and health systems. PMID:12396922

  2. Yakima Basin Fish Passage Project, Phase 2

    SciTech Connect

    Not Available

    1991-08-01

    Implementation of the Yakima Basin Fish Passage Project -- Phase 2 would significantly improve the production of anadromous fish in the Yakima River system. The project would provide offsite mitigation and help to compensate for lower Columbia River hydroelectric fishery losses. The Phase 2 screens would allow greater numbers of juvenile anadromous fish to survive. As a consequence, there would be higher returns of adult salmon and steelhead to the Yakima River. The proposed action would play an integral part in the overall Yakima River anadromous fish enhancement program (fish passage improvement, habitat enhancement, hatchery production increases, and harvest management). These would be environmental benefits associated with implementation of the Fish Passage and Protective Facilities Phase 2 Project. Based on the evaluation presented in this assessment, there would be no significant adverse environmental impacts if the proposed action was carried forward. No significant adverse environmental effects have been identified from construction and operation of the Yakima Phase 2 fish passage project. Proper design and implementation of the project will ensure no adverse effects will occur. Based on the information in this environmental analysis, BPA's and Reclamation's proposal to construct these facilities does not constitute a major Federal action that could significantly affect the quality of the human environment. 8 refs., 4 figs., 6 tabs.

  3. Assessment of Native Salmonids Above Hells Canyon Dam, Idaho, 2002-2003 Annual Report.

    Meyer, Kevin A.; Lamansky, Jr., James A.

    2004-03-01

    We assessed the relationships between specific stream attributes and Yellowstone cutthroat trout Oncorhynchus clarki bouvieri distribution and biomass at 773 stream reaches (averaging 100 m in length) throughout the Upper Snake River Basin in Idaho, in an effort to identify possible limiting factors. Because limiting factors were expected to vary across the range of cutthroat trout distribution in Idaho, separate logistic and multiple regression models were developed for each of the nine major river drainages to relate stream conditions to occurrence and biomass of cutthroat trout. Adequate stream flow to measure fish and habitat existed at 566 sites, and of those, Yellowstone cutthroat trout were present at 322 sites, while rainbow trout O. mykiss (or rainbow x cutthroat hybrids) and brook trout Salvelinus fontinalis occurred at 108 and 181 sites, respectively. In general, cutthroat trout presence at a specific site within a drainage was associated with a higher percentage of public property, higher elevation, more gravel and less fine substrate, and more upright riparian vegetation. However, there was much variation between drainages in the direction and magnitude of the relationships between stream characteristics and Yellowstone cutthroat trout occurrence and biomass, and in model strength. This was especially true for biomass models, in which we were able to develop models for only five drainages that explained more than 50% of the variation in cutthroat trout biomass. Sample size appeared to affect the strength of the biomass models, with a higher explanation of biomass variation in drainages with lower sample sizes. The occurrence of nonnative salmonids was not strongly related to cutthroat trout occurrence, but their widespread distribution and apparent ability to displace native cutthroat trout suggest they may nevertheless pose the largest threat to long-term cutthroat trout persistence in the Upper Snake River Basin.

  4. The influence of PDO and ONI on the timing of snowmelt in Idaho

    NASA Astrophysics Data System (ADS)

    Kunkel, M. L.; Pierce, J. L.

    2009-12-01

    Oceanic and atmospheric conditions in the months preceding spring snowmelt appear to greatly influence the timing of final snowmelt in Idaho. A recently published dataset of reconstructed final snowmelt dates in Idaho’s watershed uses streamflow to extend records of final snowmelt to the early 1900’s. Using this dataset, we evaluated teleconnections between the timing of final snowmelt and reconstructions of the last >100 years of coupled Pacific Decadal Oscillation (PDO) and Oceanic Nino Index (ONI). These combined datasets provide the temporal depth needed to detect correlations between changes in the timing of snowmelt and decadal-scale variations in climate (e.g. PDO). This provides a context with which to examine the factors (e.g. total snowfall, winter and spring temperatures) that control the accumulation of snow and timing of snowmelt in Idaho. Six distinct climatic regions in Idaho’s watershed appear to react uniquely to the coupled PDO/ONI induced conditions and exhibit distinct differences in the timing of final snowmelt. Idaho spans a large latitudinal gradient (42-49o N) and climatic influences on the state range from being highly influenced by Pacific-derived moisture (NW) to increased summer convective storms and monsoonal influence in the Greater Yellowstone region. When snowmelt timing was evaluated with PDO as a single element, regional final snowmelt dates responded similarly ~65% of the time during comparably coupled PDO/ONI conditions. When the timing of snowmelt was compared with PDO as two distinct phases, warm and cold, the coupled PDO/ONI conditions help to account for ~80% (warm) and 85% (cold) of the variability in the combined regional final snowmelt dates. Regionally, the coupled PDO/ONI indices could not account for ~14% to ~25% of the variability in the timing of snowmelt. We will use this study to investigate the probable response of Idaho’s snowpack to projected global increases in atmospheric and oceanic temperatures and

    2003-02-01

    In order to meet the need for protective fish screening, the Walla Walla County Conservation District (WWCCD) and the Washington Department of Fish and Wildlife (WDFW) formed a partnership to implement the WDFW Cooperative Compliance Review and Cost-Share Program. The program provides technical and financial assistance to irrigators in order to bring existing surface water diversions into compliance with state and federal juvenile fish screen criteria. The Walla Walla basin has two priority salmonid species currently listed as threatened under the Endangered Species Act, the Bull Trout and Mid-Columbia Basin Steelhead. Other partners in this effort include the Washington Department of Ecology, National Marine Fisheries Service, US Fish and Wildlife Service, and the Walla Walla Community College Irrigation Department. A Screening Oversight Committee of representatives from these agencies sets policy and resolves issues.

    Twining, Brian V.; Bartholomay, Roy C.; Hodges, Mary K.V.

    2014-01-01

    In 2013, the U.S. Geological Survey, in cooperation with the U.S. Department of Energy, drilled and constructed boreholes USGS 140 and USGS 141 for stratigraphic framework analyses and long-term groundwater monitoring of the eastern Snake River Plain aquifer at the Idaho National Laboratory in southeast Idaho. Borehole USGS 140 initially was cored to collect continuous geologic data, and then re-drilled to complete construction as a monitor well. Borehole USGS 141 was drilled and constructed as a monitor well without coring. Boreholes USGS 140 and USGS 141 are separated by about 375 feet (ft) and have similar geologic layers and hydrologic characteristics based on geophysical and aquifer test data collected. The final construction for boreholes USGS 140 and USGS 141 required 6-inch (in.) diameter carbon-steel well casing and 5-in. diameter stainless-steel well screen; the screened monitoring interval was completed about 50 ft into the eastern Snake River Plain aquifer, between 496 and 546 ft below land surface (BLS) at both sites. Following construction and data collection, dedicated pumps and water-level access lines were placed to allow for aquifer testing, for collecting periodic water samples, and for measuring water levels. Borehole USGS 140 was cored continuously, starting from land surface to a depth of 543 ft BLS. Excluding surface sediment, recovery of basalt and sediment core at borehole USGS 140 was about 98 and 65 percent, respectively. Based on visual inspection of core and geophysical data, about 32 basalt flows and 4 sediment layers were collected from borehole USGS 140 between 34 and 543 ft BLS. Basalt texture for borehole USGS 140 generally was described as aphanitic, phaneritic, and porphyritic; rubble zones and flow mold structure also were described in recovered core material. Sediment layers, starting near 163 ft BLS, generally were composed of fine-grained sand and silt with a lesser amount of clay; however, between 223 and 228 ft BLS, silt

    This report covers efforts to monitor age composition of wild adult spring/summer chinook salmon returning to the Snake River Basin. Accurately determining the ocean age proportions of wild adult spring/summer chinook salmon is important information for monitoring the status and trends of these species. During this report period, project personnel selected the preferred structure for aging, set up a database to track all samples collected, developed procedures and ordered equipment for structure preparation and reading, and aged the adults that were sampled in 1999. Chinook salmon carcasses were sampled from representative spawning areas throughout the Snake River Basin. Ocean age proportions were determined for each 5 centimeter fork length group for wild adult spring/summer chinook salmon returning to the Snake River. These ocean age proportions were applied to the number and estimated length frequency distribution of wild chinook salmon adults passing Lower Granite Dam to estimate the number of adult returns for each ocean age group.

    The U.S. Department of Energy has established long-term stewardship programs to protect human health and the environment at sites where residual contamination remains after site cleanup. At the Idaho National Laboratory Site, Comprehensive Environmental Response, Compensation, and Liability Act (CERLA) long-term stewardship activities performed under the aegis of regulatory agreements, the Federal Facility Agreement and Consent Order for the Idaho National Laboratory, and state and federal requirements are administered primarily under the direction of the Idaho Cleanup Project. It represents a subset of all on-going environmental activity at the Idaho National Laboratory Site. This plan provides a listing of applicable CERCLA long-term stewardship requirements and their planned and completed implementation goals. It proffers the Long-Term Stewardship Environmental Data Warehouse for Sitewide management of environmental data. This plan will be updated as needed over time, based on input from the U.S. Department of Energy, its cognizant subcontractors, and other local and regional stakeholders.
