The Fairbairn Dam is an earth-filled embankment dam across the Nogoa River, located southwest of Emerald in Central Queensland, Australia. Constructed in 1972 for the primary purpose of irrigation, the impoundment created by the dam serves as one of the major potable water supplies for the region and assists with some flood mitigation.[1]
Lake Maraboon with an active capacity of 1,301,000 ML (2.86×1011 imp gal; 3.44×1011 US gal) was formed by damming of the Nogoa River, and, in 2008, was Queensland's second largest dam.[1] Its capacity is approximately three times larger than Sydney Harbour. Maraboon is the Aboriginal for "where the black ducks fly".[2]
