The Nogoa River rises on the Carnarvon Range in the Carnarvon National Park in Central Queensland and flows in a north easterly direction. The river ends where it meets the Comet River north of Comet. From this point the river is called the Mackenzie River.
Queensland's second largest lake, Lake Maraboon was formed when the Fairbairn Dam was built on the river in 1972. The dam and a network of channels along the Nogoa River supplies water for the Emerald Irrigation Area.
In January 2008, the Nogoa River reached record flood levels. During the flood, water levels in the Fairbairn Dam rapidly exceeded 100%. Within a week inundations had caused severe disruptions to graziers, crops growers and to residents of Emerald when waters broke its banks. The Nogoa peaked at 15.4 m (51 ft) in Emerald on the night of January 22 2008, causing more than 2500 people to be evacuated. The unprecedented floods washed through the Ensham coal mine, temporarily halting operations in two out of six coal pits, reducing output to less than 50% and rendering a huge dragline defunct after it had been submerged.
In December 2010 - January 2011 the river flooded again.
