Blowering Dam is on the Tumut River in Australia. It is part of the Snowy Mountains Scheme. Associated with the dam is the Blowering Power Station.
The dam was completed in 1968. It holds 1,628,000 megalitres (million litres).[1] The wall height is 112 m and is constructed of earth and rockfill. The water from the dam is used for irrigation along the Murrumbidgee River, Yanco/Colombo/Billabong Creeks system, the Murrumbidgee Irrigation Area and the Colleambally Irrigation Area.
In 1978, Ken Warby set the Water speed record of 511 km/h (317.60 mph) on Blowering Dam.[2]
On 23 April 2009, New South Wales Government announced Macmahon Construction was the successful tenderer for A$33 million for parapet wall and spillway modifications, to prevent flooding in the future, which are due to begin in May 2009 and completed in 2011.[3]
