Major flooding events

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 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 was impacted by major flooding at Emerald and in the Nogoa's upper catchment.
