The Salton Sea, California’s Largest Lake – March 22nd, 201033.2N 115.7W
The Salton Sea is a saline, endorheic rift lake located directly on the San Andreas Fault. The lake occupies the lowest elevations of the Salton Sink in the Colorado Desert of Imperial and Riverside Counties in Southern California, near the border with Mexico.
The lake covers a surface area of approximately 376 sq mi (970 km2), 241,000+/- acres, the largest in California. While it varies in dimensions and area with changes in agricultural runoff and rain, it averages 15 mi (24 km) by 35 mi (56 km), with a maximum depth of 52 ft (16 m), giving a total volume of about 7,500,000 acre·ft (9.25 km3), and annual inflows averaging 1,360,000 acre·ft (1.68 km3).
The lake’s salinity, about 44 g/L, is greater than the waters of the Pacific Ocean (35 g/L), but less than that of the Great Salt Lake and is increasing by about 1 percent annually.
