The Salton Sea is a large, shallow, saline lake located in Southern California within Riverside County and Imperial County. While the dimensions vary depending upon rain and agricultural runoff, it averages 35 miles by 15 miles with a maximum depth of 44 feet. It is the largest lake in California. The lake’s salinity is greater than the Pacific Ocean, but less than that of the Great Salt Lake in Utah. The level of salt has been increasing over the years limiting the types of fish that can survive. The primary inflows are the Alamo River, the New River, and the Whitewater River. There are no major outflows. There are a number of groups, including the Salton Sea Authority and the Sonny Bono Salton Sea National Wildlife Refuse organization, working on strategies to save the Salton Sea. Towns along the Salton Sea include: Bombay Beach, Desert Beach, Desert Shores, Salton City, Salton Sea Beach, and North Shore.
