The reservoir is
impounded by the New Melones Dam, and is the fourth largest reservoir in the
State of California at 12,500 acres.
When full, the shoreline is more than 100 miles long.
The reservoir and dam
are located west of Jamestown and Sonora, and south of Angels Camp. The Archie
Stevenot Bridge, completed in 1976, carries Hwy 49 across the lake and border
between Calaveras and Tuolumne Counties.
At an elevation of 1,088 feet above sea level, New Melones Lake is part
of Reclamation’s Central Valley Project. It is located off of Highway 49, some
8 miles north of Sonora and 6 miles south of Angels Camp, in the Mother Lode. Each year, approximately 600,000 visitors
enjoy New Melones’ numerous recreational opportunities. Facilities include day
use areas; boat launch ramps; more than 300 campsites; hiking, biking and
equestrian trails; a visitor center and museum; and abundant water-based
recreation. New Melones Dam is an earth
and rock filled embankment dam on the Stanislaus River, about 5 miles (8.0 km)
west of Jamestown, California in the United States, on the border of Calaveras
County and Tuolumne County. The water impounded by the 625-foot tall dam and is
in the foothills of the Sierra Nevada east of the San Joaquin Valley. The dam
serves mainly for irrigation water supply, and also provides hydropower
generation, flood control and recreation benefits. The dam was authorized in 1944 as a unit of the federal Central Valley Project, a system designed to provide irrigation water to the fertile agricultural region of the Central Valley. It would be built by the U.S. Army Corps of Engineers (Corps), and transferred to the U.S. Bureau of Reclamation (Reclamation) upon completion. In 1966, work began to clear the foundations for a high dam that would replace an earlier, much smaller structure built by two irrigation districts. Construction of the main embankment began in 1976, and was topped out in late 1978. Water storage in New Melones Lake commenced in 1978, and the dam's hydroelectric station produced its first power in mid-1979.
New Melones was the focus of a long environmental battle during the 1970s and early 1980s; critics protested the flooding of a long scenic stretch of the Stanislaus River, which flowed over whitewater rapids through the deepest limestone canyon in the western United States. The protestors employed a variety of methods, some extreme, to prevent the filling of New Melones Lake until 1983, when record-setting floods filled the reservoir and nearly breached the dam's emergency spillway. The fight over New Melones galvanized the river conservation movement in California and influenced major water policy changes on the state and federal levels; since its completion, no other dams of its size or importance have been built in the United States.
