The reservoir's primary purpose is to provide a municipal and industrial water supply for the surrounding communities and the City of Dallas. With a shoreline of approximately 200 miles, stretching through Hunt, Rains, and Van Zandt counties, Lake Tawakoni provides water-oriented recreation for much of central northeast Texas.
There are no natural lakes in Texas; they are all man-made. Considering how hot and humid it gets here, I think it was a good idea.
