History of Thomas A. Edison Lake

Like many lakes in the Sierra, Lake Thomas A. Edison was developed for the purposes of water storage and hydroelectric power generation. Lake Thomas A. Edison was completed in 1954 with the construction of Vermillion Dam across Mono Creek, a tributary of the South Fork of the San Joaquin River. The project was completed on the 75th anniversary of the invention of the electric light and the name of Thomas Alva Edison was given to the lake in honor of the inventor. Water impounded in this lake travels down Mono Creek into the Mono-Bear Siphon which diverts the water to Ward Tunnel and then into Huntington Lake.
