Columbia Riverkeeper sues Army Corps, says hot water discharge from dams kills fish
Columbia Riverkeeper filed suit Wednesday against the U.S. Army Corps of Engineers, alleging the federal agency is illegally polluting the Columbia River with hot water, oil, and toxic chemicals that are killing fish by the thousands. Four dams operated by the Army Corps on the Columbia River between Portland, OR, and Tri-Cities, WA, discharge illegal pollution in violation of the Clean Water Act, the complaint alleges.
 

Dams on the Columbia River make the water too hot for endangered salmon and steelhead, according to government studies. Last summer, Columbia Riverkeeper captured graphic images of sockeye salmon dying from hot water in the Columbia River Gorge. Clean Water Act permits would require the my Corps to reduce heat and other types of pollution from the dams.
