PORTLAND, OR — In a stinging rebuke to the current administration’s environmental policies, U.S. District Judge Michael Simon ruled on Wednesday, February 25, 2026, in favor of a coalition of states, tribes, and conservation groups seeking to protect endangered salmon in the Columbia River Basin. The ruling effectively overrides President Trump’s June 2025 executive order, which had labeled previous salmon recovery efforts as “radical environmentalism” and withdrew the U.S. from a landmark $1 billion restoration agreement.
Judge Simon’s 47-page opinion lamented the “disappointing history of government avoidance and manipulation” and warned that the iconic fish are “disappearing from the landscape.”
The Ruling: Restoring the “Spill”
The preliminary injunction mandates immediate changes to how eight federal dams on the Columbia and Snake Rivers are operated, prioritizing fish survival over maximum hydropower generation.
- Increased “Spill”: The judge ordered the federal government to increase the amount of water “spilled” over dam crests rather than sent through power-generating turbines. This allows juvenile salmon (smolts) to bypass lethal machinery during their spring and summer migrations.
- Lower Reservoirs: The order requires dams to maintain lower reservoir levels, creating swifter, colder currents that help young fish reach the ocean more quickly.
- Rejecting the Status Quo: Simon rejected the administration’s argument that the dams were operating safely, noting that for some populations, the current “rate of slaughter” is so high it leads to generational decline.
The Political Fallout: “Radical” vs. “Essential”
The legal battle was revived after the Trump administration torpedoed the 2023 Resilient Columbia Basin Agreement—a hard-won deal between the Biden administration, Oregon, Washington, and four Native American tribes.
| Stakeholder | Position |
| The White House | Called the 2023 deal “onerous” and a threat to grid reliability and farming. |
| Gov. Tina Kotek (D-OR) | Praised the ruling, stating the judge “made the right call” against the refusal to uphold protections. |
| Tribal Nations | (Nez Perce, Yakama, Umatilla, Warm Springs) Argued the decline of salmon is a violation of 19th-century treaties. |
| Utility Groups | Warned that the ruling could lead to a 17% rate increase for Northwest electricity customers. |
The Cost of “Salmon Power”
The Bonneville Power Administration (BPA) and other federal defendants argued that the injunction would compromise the “beating heart” of the region’s energy grid.
- Grid Reliability: Opponents claim reducing hydropower during peak migration months increases the risk of blackouts.
- Carbon Emissions: Critics argue that lost hydro capacity will be replaced by natural gas plants, ironically increasing the region’s carbon footprint.
- Agriculture & Navigation: The Inland Ports and Navigation Group stated that lowering reservoirs disrupts the flow of commerce and “places the species at an alarming risk” due to infrastructure stress.
What’s Next?
- Spring Migration: The new operational changes must be implemented by March 2026 to coincide with the start of the juvenile salmon migration season.
- Long-term Litigation: This ruling is a preliminary injunction. The broader lawsuit regarding the legality of the administration’s withdrawal from the $1 billion agreement is expected to continue throughout 2026.
- The “Breaching” Question: While this ruling focuses on water flow, it keeps the door open for the highly controversial proposal to breach the four Lower Snake River dams—a move the President has vowed to block.
