Wishon Dam
Wishon Dam (National ID # CA00411) is a dam in Fresno County, California in the Sierra National Forest, in the Sierra Nevada Mountain Range. It impounds the North Fork Kings River to form Wishon Reservoir. The earthen and rockfill gravity dam was constructed in 1958 (1958) by Pacific Gas and Electric Company (PG&E) with a height of 260 feet (79 m) and a length of 3,330 feet (1,010 m) at its crest. Wishon Dam and its companion Courtright Dam, which stands about five miles to the north, along with other smaller auxiliary gravity dam structures, are elements of PG&E's Haas-Kings River Project. Courtright Reservoir serves as the upper reservoir for the Helms Pumped Storage Plant.
