Oregon, Conservation Groups Seek Emergency Dam Changes to Protect Columbia–Snake Salmon

The motions follow the U.S. withdrawal from a 2023 restoration pact that had paused the long-running case.

Overview

  • Separate preliminary-injunction motions were filed in U.S. District Court in Oregon by the state and the National Wildlife Federation, represented by Earthjustice.
  • Plaintiffs seek to lower reservoir levels and increase spill to speed juvenile salmon passage and reduce turbine encounters.
  • The requests target eight federal projects: Ice Harbor, Lower Monumental, Little Goose, Lower Granite, Bonneville, The Dalles, John Day and McNary.
  • Named defendants include the National Marine Fisheries Service and the U.S. Army Corps of Engineers, with several federal contacts returning furlough notices to requests for comment.
  • Port and navigation groups warn higher spill would hinder barge traffic and disrupt regional commerce.
