Lake Del Valle was built in 1968 by the state along with the Bethany Reservoir as part of the South Bay Aqueduct Project.
The Hetch Hetchy pipeline, built well before the reservoir, goes under the lake, and also under the road leading to the lake.  It does not connect to the lake in any way, however.

It was built to "Provide water for Irrigation, Municipal, Industrial, and Recreation uses, and to provide Flood Control"
