On December 14, 2010, the United States District Court for the Eastern District of California issued a 225 page decision (pdf) granting in part plaintiffs’ motions for summary judgment in The Consolidated Delta Smelt Cases, No. 09-407 (E.D. Cal. Dec. 14, 2010). The matter consists of five consolidated actions that all challenge the December 2008 biological opinion, jeopardy and adverse modification determinations, and reasonable and prudent alternative (RPA) for continued operation of the Central Valley Project (CVP) and State Water Project (SWP) issued by the Fish and Wildlife Service (FWS). The CVP and SWP provide water for approximately 25 million Californians. The court held for plaintiffs on numerous grounds.
