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.

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. ...

Changes in Gas Bubble Disease Signs and Survival of Migrating Juvenile Salmonids Experimentally Exposed to Supersaturated Gasses, 1995-1996 Progress Report.

Date: November 1, 1997
Creator: Absolon, Randall F.
Description: Research conducted in 1996 to evaluate (1) changes in GBD signs in juvenile salmonids resulting from passage through turbine intakes and bypass systems, and (2) relative survival during migration through the lower Snake River for juvenile salmonids experimentally exposed to supersaturation of dissolved gas.

American Heritage Rivers

American Heritage Rivers

Date: August 3, 1998
Creator: Zinn, Jeffrey A & Cody, Betsy A
Description: This report discusses the American Heritage Rivers Initiative, implemented in 1998 by President Bill Clinton. The Initiative designed 14 rivers as "American Heritage Rivers," and declared that each "will receive help over the next five years tapping federal resources to carry out their plans for revitalizing their rivers and riverfronts." This report also discusses the reactions from both supporters and detractors of the initiative, and related legislation and appropriations.

Operations of the Bonifer and Minthorn Springs Juvenile Release and Adult Collection Facilities, 1984-1986 Annual Report.

Operations of the Bonifer and Minthorn Springs Juvenile Release and Adult Collection Facilities, 1984-1986 Annual Report.

Date: May 1, 1987
Creator: James, Gary A.
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 ...
