Casitas Dam is an earthfill dam across Coyote Creek that forms Lake Casitas in Ventura County, California, near Oak View, California. Located two miles (3 km) above the junction of Coyote Creek and the Ventura River, it is 334 ft (102 m) tall and 2,000 ft (610 m) long. The structure was built by the U.S. Bureau of Reclamation, and completed in 1959. It is a key part of the Ventura River Project, and was strengthened in June–December 2000 as a seismic improvement to help withstand earthquakes greater than 6.5. Lake Casitas has a catchment of 39 sq mi (100 km²), a storage capacity of 254,000 acre⋅ft (313,000,000 m³), and provides irrigation and municipal uses for the Casitas Municipal Water District.
