Information: Lewisville Lake is the second lake to impound the waters of the Elm Fork of the Trinity River in this area. The first lake, Lake Dallas, was constructed in the 1920s by the W.E. Callahan construction Company for the City of Dallas at a cost of $3 million. The dam, completed in 1927, was built near the village of Garza and named the Garza Dam. This dam was 10,890 feet (3,320 m) long with a 567-foot (173 m) long service spillway. Lake Dallas, with its 194,000-acre-foot (239,000,000 m3) capacity and forty-three miles of shoreline, served as the principal municipal water source for the city of Dallas for 31 years. In the 1940s, a need for increased water storage capacity and additional flood control became apparent. The United States Congress passed the River and Harbor Act of 1945 and called for additional construction in the Trinity River basin. The Corps began construction of a new lake in 1948 that would not only incorporate Lake Dallas, but also impound Hickory Creek to the West, and Stewart, Panther, Cottonwood, Doe Branch, and Little Elm Creeks to the East.
