geography

River course

The river has its source in the western part of the Carnarvon Range ( Salvator Rosa Section ) and flows in a north-easterly direction. He crosses under Dawson Developmental Road at Mantuan Downs and follows the road to the west of Vandyke . Then it turns north and flows into Lake Maraboon , Queensland's second largest lake. At its northeast end, at the Fairbairn Dam , it exits again and flows through the city of Emerald , where it crosses under the Capricorn Highway and the Gregory Highway . Approx. 25 km northeast of the city, the Nogoa River turns its course to the southwest and forms the Mackenzie River together with the Comet River about 8 km north of the small town of Comet on the Capricorn Highway .

Lake Maraboon was formed when the Nogoa River was dammed by the Fairbairn Dam, built in 1972. The dam together with a number of canals supplies the Emerald Irrigation Area (German: Emerald Irrigation Area ) with water.

Floods

2008

In January 2008 the Nogoa River reached record levels. During the flooding, the water level in the reservoir rose quickly over 100%. Within a week, the river caused great damage to ranchers, grain farms and the people of Emerald after it flooded its banks. The Nogoa River in Emerald reached its high of 15.36 m on the night of January 22, 2008 - 2,500 residents of the city had to be evacuated. The unprecedented tidal wave also inundated the Ensham Mine. Operations had to be shut down in two of six coal mines , which cut production by more than 50% and damaged a giant dragline excavator after standing in the water.

2010/2011

During the floods in Queensland in 2011 , the Nogoa River rose on December 30, 2010 even above its previous high of 15.36 m. A high of 16.2 m was expected. 80% of the city of Emerald was flooded and 1,200 residents had to be evacuated.
