- Overview
Lake Texoma is one of the largest reservoirs in the United States, the 12th largest Corps of Engineers (USACE) lake, and the largest in USACE Tulsa District. Lake Texoma is formed by Denison Dam on the Red River in Bryan County, Oklahoma, and Grayson County, Texas, about 726mi upstream from the mouth of the river. Its surface spreads over 89,000 acres (360km²) at the confluence of the Red River and Washita Rivers. The damsite is approximately northwest of Denison, Texas, and southwest of Durant, Oklahoma. Lake Texoma is in Bryan, Marshall, Johnston, and Love counties, Oklahoma; and in Grayson and Cooke counties, Texas. Denison Dam and Lake Texoma were authorized for construction by the Flood Control Act approved June 28, 1938, (Public Law 75-791) for flood control and generation of hydroelectric power. The dam, spillway, and outlet works were started in August 1939 and completed in February 1944. At that time, Denison Dam was the largest rolled, earthfilled dam in the United States. The project was put into operation for flood control in January 1944. The first hydroelectric turbine was placed in operation in March 1945, while a second unit became operational in September 1949. Normal elevation of the conservation pool varies from 615 to 619 ft (187 to 189 m) National Geodetic Vertical Datum (NGVD) depending on the time of year. The flood control pool extends to elevation 645 ft (197 m) NGVD. The lake has crested the dam's spillway at a height of 640 ft (195.07 m) three times: once in 1957, again in 1990, and most recently on July 7, 2007. (USACE 2003a).[1]
