The Blowering Dam is a major ungated rock fill with clay core embankment dam with concrete chute spillway impounding a reservoir under the same name. It is located on the Tumut River upstream of Tumut in the Snowy Mountains region of New South Wales, Australia. Purposes for the dam include flood mitigation, hydro-power, irrigation, water supply and conservation. The dam is part 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.
