The Bureau of Reclamation announces the 2009 Flow Schedule from Lewiston Dam to the Trinity River.  The Flow Schedule is based on the April 1 forecast for inflows to Trinity Reservoir of 852,000 acre-feet for Water Year 2009, based on a dry year river release hydrograph.  The 2009 Flow Schedule was recommended by the Trinity Management Council on April 2, 2009, and approved by Reclamation and the U.S. Fish and Wildlife Service on April 23, 2009.    

Beginning on Sunday night, April 26, 2009, the releases on the Trinity River below Lewiston Dam will be increased incrementally from the winter base flow of 300 cubic feet per second (cfs) to a peak release of 4,500 cfs on May 1, 2009.  Flows will be reduced to the base summer flows of 450 cfs by July 5, and will remain at that level through September 30, the end of Water Year 2009.
