Courtright Reservoir is a reservoir in Fresno County, California. The reservoir is at an elevation of 8,170 feet (2,490 m) in the Sierra National Forest, in the Sierra Nevada Mountain Range, bordering the John Muir Wilderness and the Dinkey Lakes Wilderness.
The high Sierra reservoir is formed by Courtright Dam in Helms Creek canyon and has a capacity of 123,300 acre-feet (152,100,000 m3). The dam is composed of rock-fill and is 315 feet (96 m) tall, measured from the crest to the original streambed. It was completed in 1958 (67 years ago) and is owned by Pacific Gas and Electric. In 1984 the Helms Pumped Storage Powerhouse was added to the reservoir allowing it to pump water from Wishon to Courtright. Its primary purpose is hydroelectricity production.
