LEWISTON, Idaho (AP) — A controversial new study challenges long-standing science that pins salmon declines in the Snake River Basin on dams.
The Lewiston Morning Tribune reports the work by British Columbia scientist David Welch puts the blame for poor returns of adult Snake River spring and fall chinook salmon on conditions in the Pacific Ocean instead of the dams. The study argues that chinook runs from California to Alaska have suffered similar declines.
