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.
Location and features
Completed in 1961, Deep Creek Dam is a major dam, located within the Tumbarumba Shire. The dam was constructed by Thiess Bros based on engineering plans developed under contract by the Snowy Mountains Hydroelectric Authority.
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 (390×103 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).
Below the dam wall, Deep Creek flows the Little River, before emptying into the Tooma River, within the Murray-Darling basin.
