Del Valle is a reservoir located in Alameda County, California. The reservoir was created in 1968 when the Del Valle Dam was constructed on Arroyo Valle. The dam was built for flood control, irrigation, water supply, and recreation. The reservoir has a capacity of 77,000 acre-feet and serves as a crucial water source for the Bay Area. The hydrology of Del Valle is largely influenced by the snowpack in the Sierra Nevada Mountains, which melts in the spring and provides surface flow to the reservoir. The reservoir is also fed by Arroyo Valle Creek and Arroyo Mocho. Del Valle is used for agricultural purposes, including vineyards and cattle ranching, as well as for recreational activities such as boating, fishing, and camping.
