Environmental Mitigation at Hydroelectric Projects: Volume II. Benefits and Costs of Fish Passage and Protection Open
The Department of Energy, through its hydropower program, is studying environmental mitigation practices at hydroelectric projects. The study of environmental mitigation is intended to provide greater understanding of environmental problem…
Radionuclide concentrations in white sturgeon from the Columbia River. Revision 1 Open
The objectives of this study were to (1) review and summarize historical data on radionuclide concentrations in white sturgeon from the Columbia River, (2) determine present-day radionuclide tissue burdens from different locations in the C…
Radionuclide concentrations in white sturgeon from the Columbia River Open
Although radioactive releases from the US Department of Energy's Hanford Site have been monitored in the environment since the reactors began operating in 1945, recent information regarding historical releases of radionuclides has led to r…
Radionuclide concentrations in white sturgeon from the Columbia River Open
Although radioactive releases from the US Department of Energy`s Hanford Site have been monitored in the environment since the reactors began operating in 1945, recent information regarding historical releases of radionuclides has led to r…
Impacts of the Snake River drawdown experiment on fisheries resources in Little Goose and Lower Granite Reservoirs, 1992 Open
In March 1992, the US Army Corps of Engineers initiated a test to help evaluate physical and environmental impacts resulting from the proposed future drawdown of Snake River reservoirs. Drawdown would reduce water levels in Snake River res…
Spawning and abundance of fall chinook salmon (Oncorhynchus tshawytscha) in the Hanford Reach of the Columbia River, 1948--1988 Open
The Hanford Reach of the Columbia River provides the only major spawning habitat for the upriver bright (URB) race of fall chinook salmon in the mainstem Columbia River. Hanford Site biologists have conducted aerial surveys of spawning sal…
