Fairbairn Dam
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.
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. Its capacity is approximately three times larger than Sydney Harbour. Maraboon is the Aboriginal for "where the black ducks fly".
Commenced in 1968, the dam was engineered by Snowy Mountains Hydro-Electric Authority and completed in December 1972 for the purposes of irrigation and water storage. Storage of water commenced in January 1972 and the dam filled and overflowed for the first time two years later. The dam wall consists of a 5,249 thousand cubic metres (185.4×106 cu ft) earthfill embankment 823 metres (2,700 ft) in length and 46 metres (151 ft) high. The reservoir has a catchment area of 16,320 square kilometres (6,300 sq mi) with an uncontrolled concrete spillway capable of discharging 15,580 cubic metres per second (550,000 cu ft/s). The reservoir has an active capacity of 1,301,000 ML (2.86×1011 imp gal; 3.44×1011 US gal) of water; When the dam spills over it flows into the Nogoa River.
About 300 irrigators are supplied with water for cotton, citrus and other horticulture operations. The dam is relatively shallow with large areas of standing timber. There are no boating restrictions and one concrete boat ramp.
Water from the Fairbairn Dam is released down the Nogoa River to the Selma Weir for supply to the town of Emerald. Supplies are diverted by pipelines to the towns of Blackwater, Bluff, Tieri, Dysart and Middlemount. Water from the dam also supplies coal mining developments on the Bowen Basin.
The dam and reservoir are operated by SunWater.
A 50th birthday celebration for the dam is being held on Saturday 21 May 2022 sponsored by Sunwater and the Central Highlands Regional Council.
In July 2003, cotton farmers who were reliant on the dam for irrigation had their water allocation cut by 75%. In November 2006, the dam had reached its lowest level ever—just 14% of total capacity. Over that summer low inflows and high evaporation rates had dropped levels to 12%.
