Khancoban Damis a major ungatedearthfillembankmentdamwith acontrolled spillwayacross theSwampy Plain Riverin theSnowy Mountainsregion ofNew South Wales,Australia.The dam's main purpose is for the generation ofhydro-powerand is one of the sixteen major dams that comprise theSnowy Mountains Scheme,a vast hydroelectricity andirrigationcomplex constructed in south-east Australia between 1949 and 1974 and now run bySnowy Hydro.
The impoundedreservoiris called theKhancoban Reservoir.
Location and features
[edit]Completed in 1965, Khancoban Dam is a major dam, located within theSnowy Valleyslocal government area,approximately 2 kilometres (1.2 mi) southwest of the town ofKhancoban.The dam was constructed by Kaiser Engineers and Construction Incorporation based on engineering plans developed under contract from theSnowy Mountains Hydroelectric Authority.[1]
Built on a soil foundation, the dam wall comprises 629,100 cubic metres (22,220,000 cu ft) of earthfill with an internal core, and is 18 metres (59 ft) high and 1,067 metres (3,501 ft) long. At 100% capacity the dam wall holds back 26,643 megalitres (940.9×106cu ft) of water. The surface area of Khancoban Reservoir is 469 hectares (1,160 acres) and the catchment area is 788 square kilometres (304 sq mi). The controlled spillway is capable of discharging 3,540 cubic metres per second (125,000 cu ft/s).[1][2]
Located immediately upstream of the Khancoban Reservoir is theMurray 2 Power Station,a 550 megawatts (740,000 hp)conventionalhydroelectricpower station.Water from the power plant is discharged into the reservoir, before passing over the spillway of Khancoban Dam, and down the Swampy Plain River.
