In an effort to help young fish pass the dams safely to the ocean, the U.S. Army Corps of Engineers has begun implementing its 2015 Spring Fish Operations Plan. The FOP provides for spill at the four lower Snake River and four lower Columbia River dams to facilitate the timely and safe passage of juvenile salmon and steelhead. As specified in NOAA Fisheries’ 2014 Supplemental Biological Opinion, the FOP calls for spill to begin at the lower Snake River dams April 3 and lower Columbia River dams April 10. The annual plan, prepared by USACE, is coordinated with states, Tribes, and other federal agencies in the region.
