Rancho Santa Ana

Lake Casitas is a reservoir in Ventura County, California, built by the United States Bureau of Reclamation and completed in 1959. The project provides drinking water and water for irrigation. A secondary benefit is flood control. It was the venue for canoeing and rowing at the 1984 Summer Olympics. Casitas Dam was constructed on Coyote Creek, two miles (3 km) before it joins the Ventura River. Santa Ana Creek and North Fork Coyote Creek also flow into the lake. The system was designed for water from the Ventura River to be diverted into a canal under specific conditions since the impounded watershed is not sufficient to fill the lake. The dam is 279 ft (85 m) creating a lake capacity of 254,000 acre⋅ft (313,000,000 m3). The dam was built as part of the Ventura River Project.
