Lake Casitas, California

 Casitas  Dam and Reservoir

  • Located in the Los Padres National Forest in Ventura County, CA, Lake Casitas is managed by the Casitas Municipal Water District
  • The reservoir was built in 1959 by the U.S. Bureau of Reclamation, by daming Coyote Creek two miles before it joined the Ventura River.  Santa Ana Creek and the North Fork Coyote Creek also flow into the lake
  • The earth-fill dam is 285 feet tall, and 2,000 feet long.  It has a capacity of 254,000 acre-feet, 32.4 miles of shoreline, and a surface area of 1,100 acres.
  • There is a current state of emergency (2015) due to the historic drought.  Lake Casitas has dropped to below 46% for the first time since 1968
  • 3 diffusers have been installed to help control Manganese in the reservoir, which has seen an increase due to the unusually low lake levels
