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.
