Although it receives some runoff from its local watershed, most of the water is imported via the Mokelumne Aqueduct. The reservoir has a capacity of about 42,000 acre-feet (52,000,000 m3),[2] though its normal volume is about 30,250 acre-feet (37,310,000 m3).[3] The reservoir name includes "Upper" to distinguish it from Lake Chabot, several miles downstream, which was originally known as "Lower San Leandro Reservoir".
