New Hogan Dam is an embankment dam on the Calaveras River, a tributary of the San Joaquin River in central California. The dam lies east of Rancho Calaveras and impounds New Hogan Lake in the foothills of the Sierra Nevada. Built by the U.S. Army Corps of Engineers (USACE), the 210-foot (64 m)-high dam was completed in 1963. In 1986, the Modesto Irrigation District contracted with the USACE to build a base load hydroelectric plant at the dam with a capacity of 3.15 megawatts.^[2]
