Sam Rayburn Reservoir is areservoir in the United States inDeep East Texas, 70 miles (110 km) north ofBeaumont. The reservoir is fed by theAngelina River, the major tributary of theNeches River. The Reservoir is upstream of the Big Thicket National Preserve.
The reservoir's capacity is 3,997,600acre-feet (4.9310×109 m3), and is the largest lake wholly within the state of Texas. It is the ninth largest reservoir in the United States. Sam Rayburn Reservoir is operated by theUnited States Army Corps of Engineers, Fort Worth district.

Construction began September 7, 1956, and the reservoir began serving its purpose on March 29, 1965. The main purposes of the reservoir are flood control,hydroelectric power generation, and conservation of water. Construction costs, including those for recreation facilities, were estimated at $66 million.
It was known asMcGee Bend Dam and Reservoir until 1963. In September of that year, the88th Congress adopted a special resolution changing the name to "Sam Rayburn Dam and Reservoir" in honor of the recently deceasedSpeaker of the HouseSam Rayburn, a long-time champion of soil andwater conservation. Dedication ceremonies were held on May 8, 1965.
In accordance with the 1945 federal Rivers and Harbors Act, four reservoirs were originally approved for the Neches and Angelina Rivers Basin. They were designated as Dam A, Dam B, Rockland, and McGee Bend. The first to be built was Dam B, completed on the Neches River in 1953. The name was changed to Town Bluff Dam and B. A. Steinhagen Reservoir, but locals still refer to it as Dam B. In 1955, Congress approved the funding for McGee Bend Dam and Reservoir, and construction began in 1957. Congress changed the name to Sam Rayburn Dam and Reservoir in 1963, and it was formally dedicated in 1965. The Dam A and Rockland dams, which were to be on the Neches River upstream from the convergence of the Neches and Angelina Rivers, were deemed to be unnecessary and listed as "deferred".
