Reservoir Levels Weather Hydrology

Lake San Antonio is a reservoir located in Monterey County, California. The lake was created in 1965 by the construction of the San Antonio Dam on the San Antonio River. The dam was built primarily for water storage and flood control purposes. The lake's hydrology is primarily fed by the San Antonio River, which is sourced by the Nacimiento River and the San Antonio Creek. The lake's water levels are influenced by snowpack from the surrounding mountains, as well as surface flows from the river and creek. The lake is used for both agricultural purposes and recreation, including boating, fishing, and camping. The lake has also been used for water supply for nearby communities.
