CORVALLIS, Ore. — The federal government should take action to protect fish runs in the Willamette River, according to a national conservation group.
American Rivers named the Willamette in Northwest Oregon to its annual list of “America’s Most Endangered Rivers,” released Tuesday, The Corvallis Gazette-Times reported Tuesday.
The Army Corps of Engineers should act to protect imperiled spring chinook salmon and winter steelhead runs by improving operations at its 13 Willamette Basin dams, American Rivers said, adding that Congress should secure funding for the work.
An estimated 300,000 spring chinook and 200,000 winter steelhead once came back from the ocean each year to spawn in the Willamette Basin.
But those numbers have plummeted since the dams’ construction, with fewer than 5,000 spring chinook and 1,000 winter steelhead making the return trip last year, the report said.
Without functioning fish ladders, salmon and steelhead swimming upstream to spawn must be collected and trucked to the tops of the dams, while juveniles migrating downstream cannot get past dams without being forced through power turbines, the report said.
The Corps should follow the terms of a federal biological opinion issued in 2008 following a lawsuit by nonprofit watchdog Willamette Riverkeeper, which called on the Corps to make significant improvements to fish passage and water quality at its Willamette Basin dams, the report said.
