Lake Cachuma is a man-made lake or reservoir in the Santa Ynez Valley in Santa Barbara County that was created by the construction of Bradbury Dam on the Santa Ynez River in 1953. The reservoir covers 3,200 acres. The word Cachuma is derived from a Chumash village that once existed. Due to the fact that Lake Cachuma is a reservoir used for drinking water, human contact is not permitted on the lake. Small non-motorized boats are permitted and fishing is allowed. The lake is stocked with Rainbow trout. A large popular, campsite, which is operated by the Santa Barbara County Parks Department, is on the south shore of the lake and many trails are available for hiking and biking. The community of Santa Ynez is approximately 7.3 miles to the west of the dam, and Solvang is about 10.5 miles to the west.
