Coordinates: 37°35′54″N, 121°43′16″W

Lake Del Valle is located 5 miles south-southeast of Livermore, California on Arroyo del Valle. The Lake and Dam are part of the California State Water Project. It was created in 1968 as part of the South Bay Aqueduct part of the State Water Project. The lake serves in part as off-stream storage for the South Bay Aqueduct. The capacity of the lake is 77,000 acre-feet, however, the lake has a flood storage of 25,000 to 40,000 acre-feet. Thus normally stores 37,000 acre-feet to 52,000 acre-feet.

[edit] Interesting Fact

The Hetch Hetchy Aqueduct passes below the lake. It does not connect to the lake.
