Hydroelectric powerEdit

The 123,000 acre·ft (152,000,000 m3) reservoir is formed by Mammoth Pool Dam, an earth-fill dam completed in 1960. It was built by Southern California Edison for hydroelectricity production. The dam's power plant can produce up to 190 megawatts. The dam, reservoir and power plant are part of the Big Creek Hydroelectric Project, perhaps the most extensive hydroelectric system in the world.


The reservoir is also a recreation area. Activities at the lake include, swimming, fishing, camping and boating.

The reservoir is closed to the public during the month of May and the first half of June to allow migrating deer to swim across the reservoir, which spend the summer in the Sierra Nevada highlands.

The reservoir is inaccessible following the first snowstorm, usually occurring in November, as the access road is not snowplowed.
