REMARKS - Some records listed in the "Period of Record" for surface water and water quality may not be available electronically. The lake is formed by a rolled earthfill dam 24,200 ft long, including a 50 ft uncontrolled broad-crested concrete spillway. Impoundment of water began Jan. 7, 1986, after closure of the dam was completed in Dec. 1985. The flood-control outlet works consist of a 10.5 ft diameter conduit that is controlled by two 4.75 by 10.5 ft slide gates. Above an elevation of 541.0 ft, water will flow over a 50-ft-long uncontrolled broad-crested concrete spillway located 0.5 mi to left of the outlet works tower. The low-flow outlet works consist of four 3- by 5-ft slide gates having invert elevations at 486.0, 495.0, 504.0, and 513.0 ft that open to a wet-well. Discharge from the wet-well to the 10.5 ft diameter conduit is controlled by a 2- by 4-ft gate with invert at elevation 483.0 ft. A low flow bypass system consisting of a turbine pump and 10-in-diameter piping is also available for use if needed. The lake was built for water supply, conservation, and flood control. Data regarding the dam are given in the following table:
                                                                              Elevation (feet)
