REMARKS - Records fair. The lake is formed by a rolled earthfill dam 5,524 ft long, including a 1,300-ft uncontrolled broad-crested spillway in a saddle near left end of dam and a 418-ft-long dike. Deliberate impoundment began Mar. 8, 1954, and the dam was completed in Dec. 1954. The dam is owned by the U.S. Army Corps of Engineers. The lake was built for flood control and conservation storage. The controlled outlet works consist of a 22.0-ft-diameter conduit that is controlled by three 7.0- by 22.0-ft broom-type gates. The service outlet consists of a 36- by 36-in gated outlet that discharges into the flood-control conduit. There are many small diversions upstream for irrigation, municipal supply, and oil field operations. Data regarding the dam are given in the following table:
