Stevens Creek Reservoir

Reservoir Levels Weather Hydrology

Stevens Creek Reservoir is a man-made reservoir located in the Santa Cruz Mountains of California. The reservoir was created in 1935 by the construction of a dam on Stevens Creek, which is a tributary of the San Francisco Bay. The reservoir is managed by the Santa Clara Valley Water District and serves as a primary drinking water source for the cities of Cupertino, Mountain View, and Sunnyvale. The hydrology of the reservoir is influenced by the surrounding watershed, which includes both surface flow and snowpack from the nearby mountains. The reservoir is also used for recreation, including fishing, boating, and hiking, and there are several agricultural areas surrounding the reservoir. In recent years, the reservoir has experienced lower water levels due to drought conditions and increased water usage.
