Jindabyne Dam is a major ungated rockfill embankment dam across the Snowy 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 Lake Jindabyne.
Completed in 1967, Jindabyne Dam is a major dam, located approximately 2 kilometres (1.2 mi) south south-east of the relocated town of Jindabyne. The dam was constructed by a consortia of Utah-Brown and Sudamericana based on engineering plans developed under contract by the Snowy Mountains Hydroelectric Authority. Construction of the dam flooded the settlement of Old Jindabyne that accommodated approximately 300 people. Parts of Old Jindabyne can be seen when the levels of Lake Jindabyne are low. The settlement of East Jindabyne is located above what was Old Jindabyne.
The dam wall comprising 894,000 cubic metres (31,600,000 cu ft) of rockfill is 72 metres (236 ft) high and 335 metres (1,099 ft) long. At 100% capacity the dam wall holds back 688,227 megalitres (24,304.5×106 cu ft) of water. The surface area of Lake Jindabyne is 3,033.5 hectares (7,496 acres) and the catchment area is 1,880 square kilometres (730 sq mi). The spillway is capable of discharging 3,002 cubic metres per second (106,000 cu ft/s).
Work to modify the dam spillway commenced in 1994 and was ongoing as at July 2009.
Lake Jindabyne receives the flow from the Snowy River as well as its tributaries, the Thredbo River and Eucumbene River.
