Deep Creek Dam is a major ungated concrete gravity dam across the Deep Creek in the Snowy Mountains of New South Wales, Australia. The dam's main purpose is for the generation of hydro-power and is the smallest 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 Deep Creek Reservoir.
Completed in 1961, Deep Creek Dam is a major dam, located within the Snowy Valleys local government area. The dam was constructed based on engineering plans developed under contract by the Snowy Mountains Hydroelectric Authority. [1]
The dam wall comprising 4,000 cubic metres (140,000 cu ft) of concrete is 21 metres (69 ft) high and 55 metres (180 ft) long. At 100% capacity the dam wall holds back 11 megalitres (390×10 3 cu ft) of water. The surface area of Deep Creek Reservoir is 2 hectares (4.9 acres) and the catchment area is 9.68 square kilometres (3.74 sq mi). The uncontrolled spillway is capable of discharging 312 cubic metres per second (11,000 cu ft/s). [1] [2]
Below the dam wall, Deep Creek flows the Little River, before emptying into the Tooma River, within the Murray-Darling basin.
