Case Filings

Case Information:

Upper Willamette River wild spring Chinook salmon and winter steelhead are facing the threat of extinction due largely to dam operations in Oregon’s Willamette River basin. Advocates for the West filed an emergency injunction in federal court to compel the U.S. Army Corps of Engineers (the Corps) to make immediate operational changes at four of these dams.

Advocates for the West is seeking an order requiring the Corps to take immediate measures to reduce mortality and harm to these iconic fish. Such measures include:

  • Prioritizing dam operations for the benefit of the threatened fish except as needed for flood control and human health.
  • Providing deeper reservoir drawdowns at Detroit, Cougar, Fall Creek, and Lookout Point dams to aid fish passage.
  • Regulating outlets to discharge cooler water at Lookout Point and Detroit dams.
  • Improving monitoring and coordination with state and federal agencies.
