Khancoban Dam

Khancoban Dam is a major ungated earthfill embankment dam with a controlled spillway across the Swampy Plain 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 Khancoban Reservoir.

Location and features
Completed in 1965, Khancoban Dam is a major dam, located within the Snowy Valleys local government area, approximately 2 km southwest of the town of Khancoban. The dam was constructed by Kaiser Engineers and Construction Incorporation based on engineering plans developed under contract from the Snowy Mountains Hydroelectric Authority.

Built on a soil foundation, the dam wall comprises 629100 m3 of earthfill with an internal core, and is 18 m high and 1067 m long. At 100% capacity the dam wall holds back 26643 ML of water. The surface area of Khancoban Reservoir is 469 ha and the catchment area is 788 km2. The controlled spillway is capable of discharging 3540 m3/s.

Located immediately upstream of the Khancoban Reservoir is the Murray 2 Power Station, a 550 MW conventional hydroelectric power 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.
