Jounama Dam, Rockfill embankment dam in the Snowy Mountains, New South Wales, Australia

Jounama Dam is an ungated rockfill embankment dam across the Tumut River, about 2 km north by east of Talbingo. Its wall, 44 m high and 518 m long, contains 554,500 cubic metres of rock fill and impounds Jounama Pondage, which covers 381 hectares.

Completed in 1968 by Societe Dumez to plans drawn up under contract for the Snowy Mountains Hydroelectric Authority, Jounama Dam is one of sixteen major dams of the Snowy Mountains Scheme built between 1949 and 1974. Its impoundment flooded the historic valley and town of Talbingo. A 14.4 MW small hydro station was added below the wall in 2010.

Jounama Dam was built by the French firm Societe Dumez to plans drawn up under contract for the Snowy Mountains Hydroelectric Authority. Filling the reservoir submerged the old Talbingo valley and its town, and the present Talbingo was rebuilt higher up for the displaced residents.

The site offers views across the reservoir and surrounding mountain landscape, best experienced from walking paths around the dam. The area is relatively easy to access, though proper footwear is helpful for uneven terrain.

The 14.4 MW small hydro station added in 2010 sits below the dam wall on the diverted flow of the Tumut River; Snowy Hydro claims it generates enough electricity for 6,800 homes. The dam itself is an ungated rockfill embankment holding 554,500 cubic metres of rock, 44 m high and 518 m long.
