The Bureau of Reclamation, NOAA Fisheries, and U.S. Fish and Wildlife Service announced the plan for two pulse flow releases from Keswick Dam into the Sacramento River. Pulse flows are rapid increases and decreases in dam-released flows, occurring over a short time frame. The release of water helps improve survival rates for out-migrating juvenile spring-run Chinook salmon smolts through the Sacramento River in addition to the planned releases of more than 10 million fall and winter-run Chinook salmon from the Coleman National Fish Hatchery. Pulse flows releases from Keswick Dam will be targeting flows at Wilkins Slough of 11,000 cubic feet per second. The flow release for the first pulse is scheduled to begin around April 24 and reach a peak of around 9,000 cfs. Flow rates will reduce to around 7,000 cfs by April 29. The second pulse flow will begin on or around May 8 and may reach a peak of around 12,000 cfs.
