The Bureau of Reclamation, NOAA Fisheries, and U.S. Fish and Wildlife Service announced their plan today for pulse flow releases from Whiskeytown Dam into Clear Creek in May. Pulse flows are rapid increases and decreases in dam-released flows occurring over a short time. The release of water aims to advance recovery of threatened Central Valley spring-run Chinook salmon by attracting adult salmon to move upstream to take advantage of cooler summer water temperatures and improved habitat. Flow releases for the pulse will begin on May 7 and reach a peak of 900 cubic feet per second May 8 to 11.
