The Pardee Dam is a 345 foot-high dam located in the foothills of the Sierra Nevada Mountains in Northern California about 30 miles (48 km) northeast of Stockton. The dam impounds the waters of the Mokelumne River which marks the boundary between Amador and Calaveras Counties. The impounded water forms Pardee Reservoir, the primary source of water for the East Bay Municipal Utility District (EBMUD) in the San Francisco Bay Area. The reservoir normally extends over an area of 3 square miles (7.8 sq km) and has a capacity of 215,000 acre-feet. The water is transported from Pardee Reservoir across the Central Valley via three large steel pipe aqueducts to several storage reservoirs located in the hills east of San Francisco Bay which supply drinking water to the East Bay region. The water is also used to generate electric power and for recreation.
