Fitzroy River Floods
Fitzroy River flows for 733 kilometres from the King Leopold and Mueller Ranges into King Sound south of Derby, and has a catchment area of 93,829 square kilometres. In full flood the flow rate down the 15 km-wide flood plain at Fitzroy Crossing is estimated to be 23,000 cubic metres per second, which in six hours this volume of water could fill Sydney Harbour.
