Save the California Delta Alliance (STCDA) has filed its third lawsuit to stop the Delta Twin Tunnels, Sept. 15, in Sacramento Superior Court. The Delta Tunnels project, sometimes called the Bay Delta Conservation Plan (BDCP) or California WaterFix, would divert water from the Sacramento River near Hood and carry it underground in twin 40-foot-diameter tunnels, 40 miles south to the export pumps near Tracy. STCDA, known for its “Stop the Tunnels” signs and T-shirts seen all over Discovery Bay, has been fighting the tunnel project for almost 11 years.
