Construction on the dam began on June 1, 1956, and was completed on March 15, 1957. Lake Weatherford has a storage capacity of 19,600 acre-feet. The crest of the spillway is 896 feet above mean sea level. The lake covers a surface area of 1,280 acres, and the drainage area above the dam is 109 square miles. It is used as a municipal and industrial water source for Weatherford.
