Clear Lake is the largest natural freshwater lake entirely in California (why Tahoe is not?), and has the largest surface area of any freshwater lake entirely in California, the tenth largest by capacity. It is located in Lake County and is fed by runoff flowing into many streams as well as springs in Soda Bay. Its sole outlet is Cache Creek. There is a dam on Cache Creek to increase the lake’s capacity and to regulate outflow.
