Lake McClure is a reservoir in the Sierra Nevada foothills of western Mariposa County, California.
It is formed by the New Exchequer Dam impounding the Merced River, which is a tributary of the San Joaquin River. It is about 40 miles (64 km) east of Modesto.
The lake was first created by the original Exchequer Dam, built between 1924 and 1926, a concrete gravity arch dam. Exchequer Reservoir's original capacity was 281,000 acre·ft (347,000,000 m3). In 1926 its name was changed to Lake McClure to honor Wilbur Fiske McClure, Head Engineers of the State of California, who helped develop and lay out the John Muir Trail in the Sierra Mountains of California. McClure and his brother, John Clarendon McClure, also founded the town of Hacienda Heights, California.
New Exchequer Dam was built in 1967 to increase the reservoir's capacity to 1,032,000 acre·ft (1.273×109 m3). It is a rock-fill dam with a reinforced concrete face, owned by the local Merced Irrigation District, which supplies northern Merced County farms with water for irrigation through its 750-mile (1200 km) network of canals. At the base of the dam is a hydroelectric plant with a capacity of 94.5 MW.
Besides storing water for irrigation, the lake also provides opportunities for recreation. Only a small amount of water from the lake is used for drinking water, and human contact is allowed. Activities available include boating, water skiing, fishing, and camping. There is a full service marina at the lake as well. Hang gliding is popular at Lake McClure, and the site is reportedly soarable 320 days of the year.[1]
