Lake Henshaw
The lake covers approximately 1,140 acres (460 ha) and holds 55,000 acre-feet (68,000,000 m) of water when full (lowered in 1978 from its original capacity of 203,581 acre-feet (251,113,000 m) out of earthquake concerns), in addition to groundwater stored in its local basin. It drains an area of 207 square miles (540 km) at the source of the San Luis Rey River.
The lake was constructed in 1923 with the building of Henshaw Dam, an earth dam 123 feet (37 m) tall and 650 feet (200 m) long. It is owned by the Vista Irrigation District and used primarily for agricultural irrigation.
The lake features opportunities for catfish and carp fishing. Boats and cabins are available for rental. It hosts The Carp Throwdown fly fishing tournament organized by the Fly Stop.
