NATURAL DAM SALT LAKE
NATURAL DAM SALT LAKE. Natural Dam Salt Lake is seven miles west of Big Spring and three miles north of Interstate Highway 20 in western Howard County (centered at 32°13' N, 101°39' W). The lake, which is owned and operated by the Wilkinson Ranch, is usually dry, but it has a capacity of 28,000 acre-feet. It has a twenty-two-foot-high earthfill dam that reaches a spillway elevation of 2,448 feet above mean sea level. The reservoir is used for flood control. Engineering of the project was conducted by Freese and Nichols, Incorporated, and construction was by Grimmet Brothers-Synder. The lake is regulated by the Texas Water Commission, and the water is used primarily for municipal and domestic purposes.
