Lake San Antonio is a lake located primarily in southern Monterey County, California, and partially in northern San Luis Obispo County, California. The lake is formed by San Antonio Dam on the San Antonio River. The dam is 202 feet (62 m) tall and was completed in 1965[1] under Monterey County District Engineer Loran Bunte Jr . The lake and dam are owned by the Monterey County Water Authority. The lake has a capacity of 350,000 acre-feet (430,000,000 m3).

Lake San Antonio's primary purpose is to provide groundwater. Without the lake, the San Antonio River would be nearly dry in the summer months. With water in the river year-round, more of it can seep into the ground.

Most of the lake's water has dried in recent years. The 2014 Wildflower Triathlon had to accommodate the extremely low water level by moving the swim portion two miles from where it is traditionally held. Participants that year had to run along the former lake bed to get to their bikes transition area. In June 2015, the Monterey County Board of Supervisors announced it would close the camping and other facilities at Lake San Antonio effective 1 July 2015, due to costs and falling attendance.[2]
