The primary project purposes are flood risk reduction, fish and wildlife enhancement, recreation, and low flow augmentation. The lake is impounded by a rolled earthfill dam 93 ft. tall and 3,800 ft. long with a gated concrete spillway. The dam was completed in 1968 and serves a drainage area of 277 square miles. The spillway is controlled by three tainter gates in the channel section of the dam. The outlet works consist of five 5 sluices at invert and one low flow sluice. Other structures include a rolled homogenous earthen dike 15 feet high and 4,600 feet long located 3.8 miles southwest of the dam. Land includes 7,223 fee acres and 352 flowage easement acres. There are three recreation areas at the project.

Beryl ore is a natural product of the earth and may be excavated with rocks containing varying concentrations of radium-226, thorium-230 and uranium. The chemical processes to extract beryllium also separates other elements, including radium, thorium and uranium. This resulted in products with more concentrated beryllium, and incidentally generated waste streams with enhanced concentrations of radium, thorium and uranium. The products were then shipped to other facilities for further processing.
