Effects of Dissolved Gas Supersaturation on Fish Residing in the Snake and Columbia Rivers, 1996 Annual Report.

Effects of Dissolved Gas Supersaturation on Fish Residing in the Snake and Columbia Rivers, 1996 Annual Report.

Date: March 1, 1998
Creator: Schrank, Boyd P.
Description: Increased spill at dams has commonly brought dissolved gas supersaturation higher than levels established by state and federal water quality criteria in the Columbia and Snake Rivers. These increased spill volumes are intended to provide safe passage for migrating juvenile salmon. However, dissolved gas supersaturation resulting from spill in past decades has led to gas bubble disease (GBD) in fish. Therefore, during the period of high spill in 1996, the authors monitored the prevalence and severity of gas bubble disease by sampling resident fish in Priest Rapids Reservoir and downstream from Bonneville, Priest Rapids, and Ice Harbor Dams.

Effects of Dissolved Gas Supersaturation on Fish Residing in the Snake and Columbia Rivers, 1997 Annual Report.

Date: April 1, 1998
Creator: Ryan, Brad A.
Description: Large amounts of spill at dams has commonly generated levels of dissolved gas supersaturation that are higher than levels established by state and federal agencies setting criteria for acceptable water quality in the Columbia and Snake Rivers. Large spill volumes are sometimes provided voluntarily to increase the proportion of migrating juvenile salmon that pass dams through nonturbine routes. However, total dissolved gas supersaturation (TDGS) resulting from spill in past decades has led to gas bubble disease (GBD) in fish. Therefore, during the period of high spill in 1997, the authors monitored the prevalence and severity of gas bubble disease by sampling resident fish in Ice Harbor reservoir and downstream from Ice Harbor and Bonneville Dams.

Research and Recovery of Snake River Sockeye Salmon, 1994 Annual Report.

Research and Recovery of Snake River Sockeye Salmon, 1994 Annual Report.

Date: August 1, 1995
Creator: Kline, Paul A.
Description: On November 20, 1991, the National Marine Fisheries Service listed Snake River sockeye salmon oncorhynchus nerka as endangered under the Endangered Species Act of 1973. In 1991, the Shoshone-Bannock Tribe and the Idaho Department of Fish and Game initiated the Snake River Sockeye Salmon Sawtooth Valley Project to conserve and rebuild populations in Idaho. In 1994, the authors estimated the total September Redfish Lake O. nerka population at 51,529 fish (95% CI, {+-} 33,179). The Alturas Lake O. nerka population was estimated at 5,785 fish ({+-} 6,919). The total density and biomass of Alturas Lake was estimated at 27 fish/hectare ({+-} 33) and 0.7 kg/hectare, respectively. The total O. nerka population estimate for Pettit Lake was 14,743 fish ({+-} 3,683). Stanley Lake O. nerka total population size, density, and biomass was estimated at 2,695 fish ({+-} 963), 37 fish/hectare ({+-} 13), and 0.5 kg/hectare, respectively. Estimated numbers of O. nerka outmigrant smolts passing Redfish Lake Creek and Salmon River trapping sites increased in 1994. The authors estimated 1,820 (90% CI 1,229--2,671) and 945 (90% CI 331--13,000) smolts left Redfish and Alturas lakes, respectively. The total PIT tag detection rate at mainstem dams for Redfish Lake outmigrants was 21% in 1994. ...

Description: The Bonifer Springs salmon and steelhead juvenile release and adult collection facility is located in the upper Umatilla River drainage at Meacham Creek mile 2.0. The facility is one of two that are operated on the Umatilla Indian Reservation under contract with Bonneville Power Administration. Construction of the Bonifer facility was completed in the fall of 1983 and operations began in early 1984. The facility consists of a one acre spring-fed pond and a concrete fishway and adult fish holding area at the pond outlet. The facility is used for holding and spawning of adult summer steelhead and for acclimation/release of juvenile fall and spring chinook salmon and summer steelhead. The acclimation capacity is approximately 20,000 lbs. of fish. Minthorn Springs Creek is located about four miles east of Mission, Oregon, on the Umatilla Indian Reservation. It forms from several springs located immediately south of the Umatilla River. The total length of Minthorn Springs Creek is about one mile and the mouth is located at Umatilla River mile 63.7. The fishway and adult holding area of the Minthorn facility are located in Minthorn Springs Creek immediately upstream from the mouth. The juvenile raceways are located in the same general area ...

Description: The objective of the seismic reflection and side scan sonar survey is to determine the location, aerial extent, and depth of burial pits situated along the reservoir bottom of L Lake, Savannah River Site, SC. The results will be used in the overall characterization of L Lake by providing continuous profile line coverage of the bottom and subbottom sediment structure along the entire length of the project area. The results are also intended to supplement previous scientific information obtained from soil samples, aerial photography, and radiometric studies. Resultant information will be used as input for an Environmental Impact Statement of the site. Overall, the seismic reflection data will provide better descriptions of variations in the actual subbottom conditions and help identify the differing sediment layers. The side scan sonar will help identify the location of the burial pits and any other features on the bottom of the reservoir. A 3.5 kiloHertz (kHz), high resolution subbottom profiling system and an EG&G Model 260 side scan sonar system were used to meet the primary objectives of the investigation.

Description: The Confederated Tribes of the Umatilla Indian Reservation and Oregon Department of Fish and Wildlife (ODFW) are cooperating in a joint effort to increase steelhead and re-establish salmon runs in the Umatilla River Basin. As part of this program, Bonifer and Minthorn Acclimation Facilities are operated for holding and spawning adult steelhead and acclimation and release of juvenile salmon and steelhead. Regularly-scheduled maintenance was completed in 1989. Equipment and pumps received maintenance and repair. An automatic dialing system was incorporated into the alarm system at the Minthorn facility. A security company has replaced the function of the Umatilla Tribal Police which was to contact fisheries personnel in case of an alarm. The configuration of the alarm system was upgraded to activate the alarm faster and provide better access to project personnel with a pager system. A survey was completed in 1988 by Thomas Bumstead of Albrook Hydraulics Lab in Pullman, WA. to determine potential measures to address the change in course of the Umatilla River around Minthorn as a result of the flood of 1986. Options and recommendations were submitted in a report in 1989. Fish Management Consultants Inc. submitted the final reports of evaluations for both the Bonifer and ...

Redfish Lake Sockeye Salmon Captive Broodstock Rearing and Research, 1995-2000 Annual Report.

Redfish Lake Sockeye Salmon Captive Broodstock Rearing and Research, 1995-2000 Annual Report.

Date: January 1, 2001
Creator: Flagg, Thomas A.
Description: The National Marine Fisheries Service (NMFS) Northwest Fisheries Science Center, in cooperation with the Idaho Department of Fish and Game and the Bonneville Power Administration, has established captive broodstocks to aid recovery of Snake River sockeye salmon (Oncorhynchus nerka) listed as endangered under the US Endangered Species Act (ESA). Captive broodstock programs are a form of artificial propagation and are emerging as an important component of restoration efforts for ESA-listed salmon populations. However, they differ from standard hatchery techniques in one important respect: fish are cultured in captivity for the entire life cycle. The high fecundity of Pacific salmon, coupled with their potentially high survival in protective culture, affords an opportunity for captive broodstocks to produce large numbers of juveniles in a single generation for supplementation of natural populations. The captive broodstocks discussed in this report were intended to protect the last known remnants of this stock: sockeye salmon that return to Redfish Lake in the Sawtooth Basin of Idaho at the headwaters of the Salmon River. This report addresses NMFS research from January 1995 to August 2000 on the Redfish Lake sockeye salmon captive broodstock program and summarizes results since the beginning of the study in 1991.

Description: Large runs of salmon (Oncorhynchus spp.) and steelhead (O. mykiss) once supported productive Tribal and sport fisheries in the Umatilla River. By the 1920s, unscreened irrigation diversions, reduced in-stream flows, poor passage conditions, and habitat degradation had extirpated the salmon run and drastically reduced the summer steelhead run (CTUIR and ODFW 1989). Reintroduction of chinook salmon (O. tshawytscha) and coho salmon (O. kisutch) and enhancement of summer steelhead populations in the Umatilla River was initiated in the early and mid-1980s (CTUIR and ODFW 1989). Measures to rehabilitate the fishery and improve flows in the Umatilla River are addressed in the original Northwest Power Planning Council's Columbia River Basin Fish and Wildlife Program (NPPC 1987). These include habitat enhancement, hatchery production, holding and acclimation facilities, flow enhancement, passage improvement, and natural production enhancement. Detailed scope and nature of the habitat, flow, passage, and natural production projects are in the Umatilla River basin fisheries restoration plans (CTUIR 1984; Boyce 1986). The Umatilla Hatchery Master Plan (CTUIR and ODFW 1990) provides the framework for hatchery production and evaluation activities. Many agencies cooperate, coordinate, and exchange information in the Umatilla basin to ensure successful implementation of rehabilitation projects, including the Oregon Department of Fish ...

Date: January 1, 2000
Creator: Brun, Christopher
Description: The range of bull trout (Salvelinus confluentus) in the Deschutes River basin has decreased from historic levels due to many factors including dam construction, habitat degradation, brook trout introduction and eradication efforts. While the bull trout population appears to be stable in the Metolius River-Lake Billy Chinook system they have been largely extirpated from the upper Deschutes River (Buchanan et al. 1997). Little was known about bull trout in the lower Deschutes basin until BPA funded project No.9405400 began during 1998. In this progress report we describe the findings from the third year (2000) of the multi-year study aimed at determining the life history, genetics, habitat needs and limiting factors of bull trout in the lower Deschutes subbasin. Juvenile bull trout and brook trout (Salvelinus fontinalis) relative abundance was assessed in the Warm Springs River and Shitike Creek by night snorkeling. In the Warm Springs R. juvenile bull trout were slightly more numerous than brook trout, however, both were found in low densities. Relative densities of both species declined from 1999 observations. Juvenile bull trout vastly out numbered brook trout in Shitike Cr. Relative densities of juvenile bull trout increased while brook trout abundance was similar to 1999 observations in ...

Description: The Confederated Tribes of the Umatilla Indian Reservation (CTUIR) and Oregon Department of Fish and Wildlife (ODFW) are cooperating in a joint effort to supplement steelhead and re-establish salmon runs in the Umatilla River Basin. As part of this program, Bonifer and Minthorn Acclimation Facilities are operated for holding and spawning adult steelhead and fall chinook salmon and acclimation and release of juvenile salmon and steelhead. Regularly-scheduled maintenance of pumps, equipment and facilities was performed in 1991. Major repairs to one Minthorn pump were required and flood damage at Minthorn necessitated the replacement of rock and gravel around the pump house and steelhead brood holding area. Several modifications to the steelhead brood holding pond were also made to help reduce mortality. These changes appeared to be successful as evidenced by the reduced number of mortalities. Total prespawn mortality in 1990-91 was 10.4%. This compares to 20.0 to 39.0% for the previous three years at Minthorn. A total of 202 adult steelhead were collected for broodstock at Threemile Dam from November, 1990 through April, 1991 and held at Minthorn. Utilizing a 3 x 3 spawning matrix, a total of 410,356 eggs were taken from 64 females. The eggs were transferred to ...

PILOT TESTING OF MERCURY OXIDATION CATALYSTS FOR UPSTREAM OF WET FGD SYSTEMS

Date: October 4, 2002
Creator: Blythe, Gary M.
Description: This document summarizes progress on Cooperative Agreement DE-FC26-01NT41185, Pilot Testing of Mercury Oxidation Catalysts for Upstream of Wet FGD Systems, during the time period July 1, 2002 through September 30, 2002. The objective of this project is to demonstrate at pilot scale the use of solid honeycomb catalysts to promote the oxidation of elemental mercury in the flue gas from coal combustion. The project is being funded by the U.S. DOE National Energy Technology Laboratory under Cooperative Agreement DE-FC26-01NT41185. EPRI, Great River Energy (GRE), and City Public Service (CPS) of San Antonio are project co-funders. URS Group is the prime contractor. The mercury catalytic oxidation process under development uses catalyst materials applied to honeycomb substrates to promote the oxidation of elemental mercury in the flue gas from coal-fired power plants that have wet lime or limestone flue gas desulfurization (FGD) systems. Oxidized mercury is removed in the wet FGD absorbers and co-precipitates in a stable form with the byproducts from the FGD system. The coprecipitated mercury does not appear to adversely affect the disposal or reuse properties of the FGD byproduct. The current project will test previously identified, effective catalyst materials at a larger, pilot scale and in a commercial ...

Deepwater Spawning of Fall Chinook Salmon (Oncorhynchus Tshawytscha) : Spawning Near Ives and Pierce Island of the Columbia River, 2001 Annual Report.

Date: October 1, 2002
Creator: Mueller, Robert P.
Description: Pacific Northwest National Laboratory initiated studies to identify potential fall chinook salmon (Oncorhynchus tshawytscha) spawning habitat and assess the extent of spawning in deep water (>1 m) downstream of Bonneville Dam in the fall of 1999. This report provides results from 2001, the third year of our effort. The main objective of this study was to find deepwater spawning locations of fall chinook salmon in the main Columbia River channel, collect additional data on physical habitat parameters at spawning sites, and provide estimates of adult spawners in the area. The secondary objective was to map any chum salmon redds located in the deeper sections near Hamilton Slough. River flows during the spawning surveys in 2001 were lower than in 1999 and 2000. Peak spawning activity, based on redd counts and live fish seen near redds, was on or near November 9, 2001. The location of the spawning area was similar to that of 1999 and 2000. One difference was the majority of redds were found in deeper water (>1.5 m) and closer to the shoreline adjacent to Pierce Island. Because of the low river flows during the fall of 2001, only a handful of redds were found using the boat-deployed ...

Description: Concerns about the decline of native salmon and trout populations have increased among natural resource managers and the public in recent years. As a result, a multitude of initiatives have been implemented at the local, state, and federal government levels. These initiatives include management plans and actions intended to protect and restore salmonid fishes and their habitats. In 1998 bull trout (Salvelinus confluentus) were listed under the Endangered Species Act (ESA), as ''Threatened'', for the Walla Walla River and its tributaries. Steelhead (Oncorhynchus mykiss) were listed as ''Threatened'' in 1999 for the mid-Columbia River and its tributaries. These ESA listings emphasize the need for information about these threatened salmonid populations and their habitats. The Washington Department of Fish and Wildlife (WDFW) is entrusted with ''the preservation, protection, and perpetuation of fish and wildlife....[and to] maximize public recreational or commercial opportunities without impairing the supply of fish and wildlife (WAC 77.12.010).'' In consideration of this mandate, the WDFW submitted a proposal in December 1997 to the Bonneville Power Administration (BPA) for a study to assess salmonid distribution, relative abundance, genetics, and the condition of salmonid habitats in the Walla Walla River basin. The primary purposes of this project are to collect ...

DOE SAPPHIRE PROJECT

Date: March 1, 2000
Creator: Pickrell, Dr. Gary R.
Description: Since this is the first report for this project an extensive background section follows on the theory of operation of the single crystal sapphire sensor technology which will be developed and field tested at the Wabash River Coal Gasification Facility. Requirements for the temperature sensors for implementation in the coal gasifiers has been established in conjunction with the industrial partner, Dynegy. Coal slag immersion tests indicate good corrosion resistance of the single crystal sapphire. However, a more sophisticated corrosion apparatus has been constructed in order to test the optical attenuation of a single crystal sapphire fiber immersed in the coal slag at high temperature. These results will be reported in the next period. The data to date for sapphire sensor development is promising. More extensive data on the sapphire fiber sensor development will be reported for the next period.
