Wright Patman Dam

Wright Patman Dam (formerly called Texarkana Dam) is an earth-fill dam across the Sulphur River in northeast Texas in the United States. The water impounded by the dam forms Wright Patman Lake.

Geography
Wright Patman Dam is situated 9 mi southwest of Texarkana, Texas. The dam straddles the border between Bowie County and Cass County.

The dam is 18,500 ft long, with a 200 ft wide spillway. The top of the dam is 286 ft above sea level, or 100 ft above the riverbed.

History
Wright Patman Dam, then known as Texarkana Dam, was authorized as part of the Flood Contract Act of 1946. Construction began in 1948, and the Sulphur River was blocked and routed through the dam's control gates in 1953. The gates were closed and water impounded in 1956. In 1973, the project was renamed in honor of Congressman Wright Patman of Texas.

The dam's design and construction were the responsibility of the New Orleans District of the U.S. Army Corps of Engineers. In 1973, responsibility for the dam and lake were transferred to the Fort Worth District of the Corps of Engineers.
