Lake Mineral Wells (Brazos River Basin)
Lake Mineral Wells is located about four miles east of Mineral Wells in western Parker County, on Rock Creek, a tributary of the Brazos River. It was owned and operated by the City of Mineral Wells for water supply purposes. Construction to the original dam began in 1918 and was completed in September 1920. In 1943 (but completed in January 1944), modifications were made to the original spillway, which increased the lake level by 2 feet. According to 1992 survey, the lake has a capacity of 7,065 acre-feet and encompasses a water surface of 440 acres at the normal elevation 863.4 feet above mean sea level. The dam controls a drainage area of about 63 square miles.
