River course

The river rises on the eastern slopes of Mount Ewan in the Carborough Range and initially flows south-southwest along the Denham Range . At the end of these mountains, diverted by a deep ditch, he turns his course south to the small town of Moranbah . There he turns to the southeast, under the Peak Downs Highway and the Fitzroy Developmental Road near Bombandy . Along the Broadsound Range it continues its way to the southeast and flows into the Mackenzie River at its southern end .
