The Corps of Engineers provides for counting of adult salmon, lamprey, shad, sturgeon and bull trout migrating through Corps-owned hydro-electric facilities: Bonneville, The Dalles, John Day and McNary on the Columbia River; Ice Harbor, Lower Monumental, Little Goose and Lower Granite on the Snake River.
Fish counts are estimates of the actual numbers of passing fish. More detailed information about count schedules at each dam may be found in the current Fish Passage Plan
While fish counts are still being performed, we are currently experiencing technical difficulties with our fish count web application. In the meantime, you may view daily fish count reports by visiting the Fish Passage Center's Daily Passage Report
