The dam's purpose includes flood mitigation, hydro-electric power, irrigation, water supply and conservation. The impounded reservoir is called Lake Glenbawn.
Glenbawn Dam was created through enabling legislation enacted through the passage of the Шаблон:Cite Legislation AU. The Act appropriated A£1 500 000 as the estimated cost of construction of the dam.[1]
Location and features
Commenced in late 1947 and completed in late 1957, the Glenbawn Dam is a major dam on the Hunter River and is the fourth largest earth-filled embankment dam in Australia by volume. The dam is located approximately Шаблон:Convert east of the town of Scone on the upper reaches of the river. The dam was built by the New South Wales Water Conservation & Irrigation Commission to supply water for irrigation and flood mitigation.[2][3][4]
The dam wall height is Шаблон:Convert and is Шаблон:Convert long. The maximum water depth is Шаблон:Convert and at 100% capacity the dam wall holds back Шаблон:Convert of water at Шаблон:Convert AHD. The dam has an additional reserve capacity of Шаблон:Convert to hold floodwaters that reduce flooding downstream. The surface area of Lake Glenbawn is Шаблон:Convert and the catchment area is Шаблон:Convert. The ungated concrete chute spillway is capable of discharging Шаблон:Convert.[2][3][4] An upgrade of facilities completed in 1987 took the height of the dam wall from Шаблон:Convert to its current height.[2][3] Glenbawn Dam is operated in conjunction with Glennies Creek Dam. The two dams supply water requirements along Шаблон:Convert of the Hunter River from Glenbawn to the tidal reaches near Maitland.[2]
The name Glenbawn originates after a riverside property resumed for part of the storage area.[5]
Power generation
A hydro-electric power station generates up to Шаблон:Convert of electricity from the flow of the water leaving Glenbawn Dam with an average output of Шаблон:Convert per annum. The station was completed in January 1995. The facility is managed by AGL Energy.[6]
