San Francisco Baykeeper, California Sportfishing Protection Alliance, Restore the Delta, and Friends of the River today filed a lawsuit against the US Fish and Wildlife Service and the Secretary of the US Department of the Interior for failing to deliver a legally required initial determination whether or not to list the San Francisco Bay’s population of White Sturgeon as a threatened species. … White Sturgeon are North America’s largest freshwater fish. … (T)he state plans to build new diversions—including Sites Reservoir and the Delta Tunnel—which represent an imminent threat to the White Sturgeon, as well as other native fish, including Central Valley Chinook Salmon that support the state’s coastal salmon fishery.
