Clear Lake (bottom right quadrant) is the largest natural freshwater lake entirely in California, and has the largest surface area of any freshwater lake entirely in California, the tenth largest by capacity.
The geology of Clear Lake is chaotic, with numerous small faults being present in the south end of the lake as well as many old volcanoes, the largest being Mount Konocti, sitting at the middle of the lake’s south shore (visible near the bottom edge of this this orthorectified image).
