Lake Tawakoni is a 36,700-surface-acre reservoir with a capacity of 936,200 acrefeet. The spillway crest elevation is 437.5 feet above mean sea level. The 200-mile-long shoreline makes its way through Rains, Hunt, and Van Zandt counties. Located some 50 miles east of Dallas and 25 miles south of Greenville, the lake is impounded by Iron Bridge Dam, an earthfill dam with a concrete spillway constructed by Forrest and Cotton, engineers. The project is owned and operated by the Sabine River Authority. Dam construction began in January 1958 and was completed in December 1960 to provide a municipal and industrial water supply for the communities of the area and the City of Dallas.
The area around Lake Tawakoni is rich in Native American history having been occupied by "prehistoric Indians" and used as a stop over for many of the historic Native American Indian tribes for which the lake is named.
Lake Tawakoni is still a virtually undiscovered lake in Texas. It is still clean and un-crowded, its size making it ideal for recreational water sports. A Texas State Park opened on its shores in 2001, providing the public campgrounds and recreational facilities that Texas State Parks are famous for.
