Willamette River Basin Project Supplemental Biological Assessment

July 11, 2008, NOAA Fisheries released a biological opinion (BiOp) addressing the effect of the operation of 13 dams on Willamette River tributaries and 42 miles of levees on 13 populations of salmon and steelhead protected by the federal Endangered Species Act (ESA).

The Willamette BiOp covers actions through 2023 and strengthens the initial proposal from the U.S. Army Corps of Engineers, Bonneville Power Administration and the U.S. Bureau of Reclamation (Action Agencies) to provide adequate protection for two ESA-listed species on the Willamette River: winter steelhead and chinook salmon.

The additional measures (in a Reasonable and Prudent Alternative), combined with the Action Agencies' Proposed Action, will allow for survival of the species with an adequate potential for recovery and avoid modification of critical habitat.
