Happy Jacks Dam is a major ungated concrete gravity dam across the Tumut River in the Snowy Mountains region 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 the Happy Jacks Pondage that is fed by the Tumut River. Immediately downstream of the dam wall, Happy Jacks Creek forms its confluence with the Tumut River.[1][2]
Location and features
Completed in 1959, Happy Jacks Dam is a major dam, located within the Tumbarumba Shire. The dam was constructed by a consortia comprising Kaiser-Walsh-Perini-Raymond based on engineering plans developed by the United States Bureau of Reclamation under contract from the Snowy Mountains Hydroelectric Authority.[3]
The dam wall comprising 8,950 cubic metres (316,000 cu ft) of concrete is 29 metres (95 ft) high and 76 metres (249 ft) long. At 100% capacity the dam wall holds back 271 megalitres (9.6×106 cu ft) of water. The surface area of Happy Jacks Pondage is 53 hectares (130 acres). The uncontrolled spillway is capable of discharging 1,827 cubic metres per second (64,500 cu ft/s).[3][4]
