Huntington Lake, Mountain reservoir in Fresno County, California.

Huntington Lake is a reservoir on Big Creek in the Sierra Nevada at 6,955 feet, formed by four dams and covering 1,441 acres. Its long arm reaches eastward behind a tree-covered ridge, with small floating structures moored near the western shore. State Route 168 runs along the east shore.

Huntington Lake was created in 1912 as part of the Big Creek Hydroelectric Project conceived by engineer John S. Eastwood to power a growing California. It was named for railroad magnate Henry Edwards Huntington, who financed the earliest development work. Three dams were completed in 1913; a fourth, finished in 1919, raised capacity, and the original three were later raised and faced with concrete.

The lake's name honors Henry Edwards Huntington, the railroad magnate who financed the earliest work on the Big Creek project. Today the Fresno Yacht Club organizes the annual High Sierra Regatta, and nine campgrounds and scout camps such as Camp Kern and Camp Oljato occupy the shores.

Nine campgrounds around the lake offer facilities for tent and vehicle camping with varying amenities and setups. Most locations require booking in advance, especially during warmer months.

The B-24 that crashed into the lake on December 6, 1943, had taken off from Hammer Field in Fresno to search for another bomber missing since the previous day. Two of the eight men aboard bailed out and survived; the wreckage and the six remaining crew were found in August 1955 when the lake was drained for dam repairs.
