Guthega Dam is concrete gravity dam with an uncontrolled spillway across the Snowy River in the Snowy Mountains of New South Wales, Australia. The dam's main purpose is for the storage of water used in the generation of hydro-power . It is the first to be completed of the sixteen major dams of 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 Guthega Pondage.
Guthega dam is one of the sixteen major dams of the Snowy Mountains Scheme. It was completed in 1955 and is located 5 kilometres (3.1 mi) northwest of Perisher Valley, in the Kosciuszko National Park. The dam was constructed by Semler Engineering based on engineering plans developed under contract by the Snowy Mountains Hydroelectric Authority, with Albert Francis Ronalds as Chief Civil Designing Engineer. [1] [2]
The dam wall, comprising 44,100 cubic metres (1,560,000 cu ft) of concrete, is 34 metres (112 ft) high and 139 metres (456 ft) long. The uncontrolled spillway is capable of discharging reservoir overflow at rates up to 1,416 cubic metres per second (50,000 cu ft/s). At 100% capacity the dam wall holds back 1,604 megalitres (56.6×10 6 cu ft) of water with a surface area of 19.4 hectares (48 acres) The catchment area is 91 square kilometres (35 sq mi), including the Guthega river, Pounds creek, Farm creek and the upper reaches of the Snowy River. [1] [3]
Approximately 5.5 kilometres (3.4 mi) downstream of the dam wall and using water from Guthega Pondage, is the above ground Guthega conventional hydroelectric power station. Commenced in 1951 and completed in 1955, the power station has two Francis turbines comprising English Electric generators, with a combined generating capacity of 60 megawatts (80,000 hp) of electricity; a net generation of 172 gigawatt-hours (620 TJ) per annum; and has 246.9 metres (810 ft) rated hydraulic head. Water flows through the turbines at the rate of 28.3 cubic metres per second (1,000 cu ft/s). [4]
Dartmouth Dam is a large rock-fill embankment dam with an uncontrolled chute spillway across the Mitta Mitta, Gibbo and Dart rivers, the Morass Creek and a number of small tributaries. The dam is located near Mount Bogong in the north-east of the Australian state of Victoria. The dam's purpose includes irrigation, the generation of hydro-electric power, water supply and conservation. The impounded reservoir is called Dartmouth Reservoir, sometimes called Lake Dartmouth. The Dartmouth Power Station, a hydro-electric power station that generates power to the national grid, is located near the dam wall.
The Snowy Mountains Scheme, also known as the Snowy Hydro or the Snowy scheme, is a hydroelectricity and irrigation complex in south-east Australia. Near the border of New South Wales and Victoria, the scheme consists of sixteen major dams; nine power stations; two pumping stations; and 225 kilometres (140 mi) of tunnels, pipelines and aqueducts that were constructed between 1949 and 1974. The Scheme was completed under the supervision of Chief Engineer, Sir William Hudson. It is the largest engineering project undertaken in Australia.
