Tumut Two Dam or Tumut Two /ˈtjuːmət/ is a major ungated concrete gravity dam across the upper reaches of the Tumut River in the Snowy Mountains of New South Wales, Australia. The dam's main purpose is for the generation of hydro-power and is one of the sixteen major dams that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro.
The impounded reservoir is called the Tumut Two Reservoir, or less formally, the Tumut Two Pondage.
Completed in 1961, Tumut Two Dam is a major dam, located approximately 3 kilometres (1.9 mi) west of Cabramurra. The dam was constructed by a consortia comprising Kaiser-Walsh-Perini-Raymond based on engineering plans developed by the Snowy Mountains Hydroelectric Authority and the United States Bureau of Reclamation under contract from the Snowy Mountains Hydroelectric Authority.
The dam wall comprising 48 cubic metres (1,700 cu ft) of concrete is 46 metres (151 ft) high and 119 metres (390 ft) long. At 100% capacity the dam wall holds back 2,677 megalitres (94.5×106 cu ft) of water. The surface area of Tumut Two Reservoir is 182 hectares (450 acres) and the catchment area is 396 square kilometres (153 sq mi). The spillway is capable of discharging 2,152 cubic metres per second (76,000 cu ft/s).
