For Release: April 23, 2010

The Bureau of Reclamation announces the 2010 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 1,310,000 acre-feet for Water Year 2010, based on a normal year river release hydrograph.  The 2010 Flow Schedule was recommended by the Trinity Management Council on April 8, 2010, and approved by Reclamation and the U.S. Fish and Wildlife Service.   

Beginning Thursday night, April 22, 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 6,000 cfs on May 2, 2010.  Flows will be reduced to the base summer flows of 450 cfs by August 2 and will remain at that level through September 30, the end of Water Year 2010.
