Lewisville Lake

Lewisville Lake is on the Elm Fork of the Trinity River one mile northeast of Lewisville and fifteen miles southeast of Denton in southeastern Denton County. The reservoir is owned by the United States government and operated by the United States Army Corps of Engineers, Fort Worth District; its purpose is to control potential flood waters originating within the Elm Fork drainage basin. In addition, the lake assists in soil conservation, serves as a recreational area, and provides water for local municipalities.

Lewisville Lake is the second water-storage reservoir to impound the waters of the Elm Fork on this site. The first facility, Lake Dallas, served for thirty-one years as the principal source of municipal water for its owner, the city of Dallas. Construction of this lake, with its eighty-foot-high, 11,000-foot-long dam located near the village of Garza (renamed Lake Dallas, Texas, in 1929), began in February 1928. The lake was built by the W. E. Callahan Construction Company at a cost of just over $3 million. It had a 194,000-acre-foot capacity at an elevation of 525 feet and covered over 10,000 acres. It was nine miles long and three miles wide and had a forty-three-mile shoreline.
