On September 1, 2021, the U.S. District Court for the District of Oregon issued an interim injunction that requires the Corps to undertake specified actions to improve fish passage and water quality at several Willamette Valley Project dams for the benefit of Upper Willamette River (UWR) spring Chinook salmon and UWR winter steelhead salmon, both of which are listed as threatened under the Endangered Species Act. The Corps is working in coordination with the National Marine Fisheries Service, U.S. Fish and Wildlife Service, Bonneville Power Administration, and U.S. Bureau of Reclamation to implement the injunction measures, some of which began in fall 2021.
The interim injunction describes the specific measures and is available on this page. Some of the injunction measures necessitate additional refinement by a panel appointed by the Court. Future court-ordered implementation plans for those measures will be posted to this page as they become available. The Corps will also post the results of research, monitoring, and evaluation (RM&E) associated with the injunction measures on this page as they become available.
