Fairbairn Dam The Fairbairn Dam is an earthfill-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 the major potable water supplies for the region and assists with some flood mitigation. Lake Maraboon with an active capacity of 1301000 ML was formed by damming of the Nogoa River, and, in 2008, was Queensland's second largest dam. Maraboon is the Aboriginal for "where the black ducks fly".
