Even the basaltic terrain and the rocksthemselves, were put to productive use. 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 CreekIdahosince Underwater time- lapse videography is a passive methodology that does not trap or handle this Endangered Species Act listed species.

Peak net upstream movement of 41 adults occurred on July 8. Because flood boundaries could not be located exactly, only a generalized flood-prone map was developed. The last fish passed through the Lake Creek fish counting station on September 6.

Seventeen completed redds 2. Model simulation of the year peak flow cubic feet per second in reaches upstream from State Highway 22 indicated that flow was confined within channels even when all flow was routed to one channel. Dissolution of evaporite minerals, associated with Pleistocene Lake. This project has successfully demonstrated the application of underwater video monitoring to accurately quantify chinook salmon abundance in Lake Creek inand The adult salmon spawner escapement estimate into Lake Creek in was fish, the largest escapement since the project began.

Water from a third spring contained slightly anomalous amounts of uranium, and two species of mosses at the spring contained anomalous uranium and high levels of both cadmium and lead.

Secesh River chinook salmon represent a wild spawning aggregate that has not been directly supplemented with hatchery fish. Resource managers are implementing a program to restore these spring creeks for the recovery of Yellowstone cutthroat trout and ecosystem health.

The reach-based geomorphic functional scoring provides an indicator of relative restoration potential for each reach, and is one of the factors used in determining site-specific priorities for protecting, enhancing, and restoring spring creeks on the Fort Hall Bottoms. 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 CreekIdahosince Underwater time-lapse videography is a passive methodology that does not trap or handle this Endangered Species Act listed species.

Gass, Carrie; Olson, Jim M. Data relating to supplementation treatment releases, juvenile sampling, juvenile PIT tagging, brood stock spawning and rearing, spawning ground surveys, and snorkel surveys were used to evaluate project data points and augment past data.

Adopting an ecological perspective, the paper concludes with a discussion of the possible functions of these unique resources for the desert populations that once called the INL home.

Birch Creek flows southward about 40 miles through an alluvium-filled valley onto the northern part of the Idaho National Engineering and Environmental laboratory site on the eastern Snake River Plain. Over the past 13, years, human populations have lived in and productively utilized the natural resources offered by the cold desert environment of the northeastern Snake River Plain in eastern Idaho.

Flow also was simulated with the culvert removed.

Within an overall framework of hunting and gathering, groups relied on an intimate familiarity with the natural world and developed a variety of technologies to extract the resources that they needed to survive. The water samples were analyzed for field parameters, major ions, silica, nutrients, dissolved organic carbon, trace elements, tritium, and the stable isotope ratios of hydrogen, oxygen, carbon, sulfur, and nitrogen. The exact location of flood boundaries on Birch Creek could not be determined because of the highly braided channel and the many anthropogenic features such as the trench, highway, and diversion channels in the study area that affect flood hydraulics and flow.

Simulated water-surface elevation at this crossing was 0. Arkosic sandstones and conglomerates of Tertiary age beneath the Challis Volcanics of Eocene age at Basin Creek10 km northeast of Stanley, Idahocontain uranium-bearing vitrainized carbon fragments.

This project has successfully demonstrated the application of underwater video monitoring to accurately quantify chinook salmon abundance in Lake Creek in, and The adult salmon spawner escapement into Lake Creek in was fish. The remaining cubic feet per second flowed southwestward in a trench along the north side of the highway. 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 ly reported.

Redd count expansion methods were compared to underwater video determined salmon spawner abundance in Lake Creek in Expanded index area redd count point estimates and intensive area redd counts inestimated from 1. A large wetland and floodplain complex adjacent to the Snake River in southeastern IdahoUSA, encompasses numerous spring-fed creeks that originate on the floodplain and discharge at their confluence with the Snake River and American Falls Reservoir. Twenty-six ventral clipped, and 28 natural adult spring chinook were transported above the weir.

from the geomorphic assessment fostered the development of a conceptual model for spring creek function, whereby degraded bank conditions represent the primary controlling factor of decreased geomorphic function and fish habitat quality. In there were 2. These suggest that, in the Basin Creek area, moss sampling at springs may give a more reliable indication of uranium occurrence than would water sampling.

Forty-three females were used for supplementation brood stock, and 45 supplementation ventral fin-clipand 45 natural unmarked adults were released upstream of KNFH to spawn naturally. Useful items were abundant and found everywhere on the landscape.

Spatial and temporal distribution of 37 adults released above the KNFH weir was determined through the use of radio telemetry.

Groundwater geochemistry was influenced by reactions with rocks of the geologic terranes—carbonate rocksrhyolite, basalt, evaporite deposits, and sediment comprised of all of these rocks. These data were summarized in a GIS database and used to quantify the overall geomorphic functioning of each reach. Simulation of water-surface elevations for a hypothetical year peak flow in Birch Creek at the Idaho National Engineering and Environmental Laboratory, Idaho.

The U. This effort requires an understanding of the natural and anthropogenic geochemistry of groundwater at the INL and of the important physical and chemical processes controlling the geochemistry. The economic potential of these sandstones and conglomerates is currently being assessed.

The studyconceptual model and restoration strategy were communicated to resource managers and regional stakeholders through a graphically. The mineralogy of the sediment and rock samples was analyzed with X-ray diffraction, and the mineralogy and petrology of the rock samples were examined in thin sections.

Geochemistry of groundwater in the Beaver and Camas Creek drainage basins, eastern Idaho. Migrating salmon in Lake Creek. The primary geochemical processes appear to be precipitation or dissolution of calcite and dissolution of silicate minerals. This paper presents a preliminary classification scheme for rock structures built on the Idaho National Laboratory landscape by prehistoric aboriginal populations, including discussions of the overall architecture of the structures, associated artifact assemblages, and topographic placement.

Data used in this study include petrology and mineralogy from 2 sediment and 3 rock samples, and water-quality analyses from 4 surface-water and 18 groundwater samples. A geomorphic assessment along 38 km of three spring creeks was completed by collecting data at several transects within distinct geomorphic reaches, and by collecting data continuously throughout all reaches.

Uranium in spring water and bryophytes at Basin Creek in central Idaho. Redd count expansion values had unknown variation associated with the point estimates. Where the highway crosses Birch Creekabout cubic feet per second of water was estimated to move downstream cubic feet per second through a culvert and cubic feet per second over the highway.

Agricultural practices near and south of Dubois and application of road anti-icing liquids on U. Interstate Highway 15 were likely sources of nitrate, chloride, calcium, and magnesium to groundwater. Several domestic wells in close proximity to this line have exhibited increasing fl The approximate 51, acre project area is located about two miles east of Council, Idaho.

Delineation of areas at the Idaho National Engineering and Environmental Laboratory devonian Idaho date night would be inundated by a year peak flow in Birch Creek is needed by the US Department of Energy to fulfill flood-plain regulatory requirements.

Two redds were observed and no carcasses were collected on Pete King Creek. The first fish passage on Lake Creek was recorded on June 26, 15 days after installation of the fish counting station. Fish per redd s in Lake Creek have varied widely. Peak net upstream movement of 52 adults occurred on June Peak of total movement activity was July 3. A total of 69 redds were counted and 79 carcasses were recovered on Clear Creek.

Monitoring and evaluation of spawning success was continued on Clear and Pete King creeks. For Clear Creekminimum survival estimates to Lower Granite Dam of hatchery produced supplementation and naturally produced PIT tagged smolts, were For Pete King Creekminimum survival estimates to Lower Granite Dam, of hatchery produced supplementation smolts and naturally produced smolts PIT tagged as parr and presmolts, were Adults collected for broodstock in represented the final adult broodstock group collected for the ISS project.

Our objectives were to evaluate the physical characteristics of these spring creeksdevelop a conceptual model of their geomorphic function, compare the restoration potential of individual reaches, and communicate our findings to a broad audience of resource managers and regional stakeholders in order to foster restoration planning.
