Clear Lake is a natural freshwater lake in Lake County, California and is fed by runoff flowing into many streams as well as springs in Soda Bay. The springs in Soda Bay bring carbon dioxide to the surface, hence the name of the bay. The lake's sole outlet is Cache Creek. In 1914, Cache Creek Dam was constructed at this point in order to increase the lake's capacity and to regulate its outflow.BackgroundClear Lake is 19mi by 8mi at its widest point, with surface area of 43785acre and a 1155000acre.ft capacity. Average depth is 27ft, maximum is 60ft, lake elevation is 1329ft, average water temp is 40F in winter and 76F in summer.Clear Lake is believed to be one of the oldest lakes in North America, due to a geological fluke. The lake sits on a huge block of stone which slowly tilts in the northern direction at the same rate as the lake fills in with sediment, thus keeping the water at roughly the same depth. Core samples of the lake's sediments, taken by U.S. Geological Survey geologists in 1973 and 1980, indicate that the lake is at least 480,000 years old. Some experts feel that Mono Lake, to the east of the Sierra Nevada in California, is older than Clear Lake. However, the sedimentary history of Clear Lake is unbroken, while Mono Lake's sediments have been disturbed by past eruptions of the Long Valley Caldera and associated volcanoes.

  • Seriously, "Clearlake", it is not. This lake has so much filamentous blue-green algae that a more fitting name, as many reviewers have noted, would be "Green Pea Soup Lake. Excess nutrients (sewage, f...  more »
