Increased Spring Spill Underway at Four Lower Snake River Dams by Evan Ellis Daily Fly, April 8, 2026

PULLMAN, WA -- Annual spring spill over the Four Lower Snake River Dams in Southeastern Washington is underway.

A recent federal court order is requiring increased spill this season. The annual action helps move young salmon and steelhead migrate downriver. The water that's spilled over the top of the dams is diverted away from the turbines for power generation. Spring spill began last week.

The U.S. Army Corps of Engineers is alerting river users to be cautious of faster currents and high water levels below the dams.
