The Tumut River (/ˈtjuːmət/), a perennial stream that is part of the Murrumbidgee catchment within the Murray–Darling basin, is located in the Snowy Mountains and South West Slopes districts of New South Wales, Australia.
The Tumut River rises on the northern face of Mount Jagungal in the Snowy Mountains at 1,430 metres (4,690 ft) and flows generally north by west, joined by twelve tributaries including the Doubtful Creek, Happy Jacks Creek and Goobarragandra River before meeting its confluence with the Murrumbidgee River, at Darbalara near the town of Gundagai; descending 1,210 metres (3,970 ft) over its 182-kilometre (113 mi) course.
Between Cabramurra and Tumut, the natural course of the Tumut River has been altered as a result of the construction of the Snowy Mountains Scheme. A series of sixteen major dams and seven hydro-electric power stations were constructed between 1949 and 1974 to harness the flow of the Tumut and Snowy rivers. The Tumut River is impounded by six dams, located at Happy Jacks Dam, Tumut Pond Dam, Tumut Two Dam, Talbingo Dam, Jounama Dam, and Blowering Dam. Four hydro-power stations are located adjacent to the river flow. Although a relatively short river, the natural flow of the Tumut River is quite high, as it drains the snowmelt and other runoff from a large proportion of the northern Snowy Mountains. The natural flow of the river is amplified by water transferred from the Tooma River and Lake Eucumbene by the Snowy Mountains Scheme.
