San Andreas Lake
The San Andreas Lake ( Laguna de San Andreas Spanish ) is an artificial lake at 138 meters above sea level in the reduction of the San Andreas Fault, near the cities of Millbrae and San Bruno in San Mateo County, California, United States. It is crossed by the San Andreas Creek and fed by the flowing water of a catchment area of eleven square kilometers and holds a water volume of 23.469 million cubic meters. He has a water surface of 220 hectares, which is stretched to a maximum length of 4.8 kilometers.
Gaspar de Portolà arrived here on November 4, 1769, shortly before his discovery of the bay of San Francisco over. The valley of the San Andreas Creek was named in 1774 by Francisco Palou as " Cañada de San Andrés ". Professor Andrew Cowper Lawson of the University of California, Berkeley, who discovered the San Andreas fault in the vicinity of the lake, named in 1895 after the rejection of the lake. The original smaller natural water basin was enlarged in 1875 by the establishment of an earth dam and now serves as a water reservoir and must therefore not be used as a bathing water. The dam survived the San Francisco earthquake of 1906 without damage.
