The Lafayette Reservoir is an open-cut man-made terminal water storage reservoir owned and operated by the East Bay Municipal Utility District (EBMUD). Completed in 1933, it was intended solely as a standby water supply for EBMUD customers. EBMUD opened the reservoir for public recreation in 1966. It is located off of California State Route 24 and a mile from the Lafayette BART station, in Contra Costa County, California, United States.
