Course and features
The headwaters of the Wickham River are situated on an area of rugged stony hills and a sandstone plateau as the river rises on the southeastern slopes of Mt Kimon. It flows generally northeast, joined by seven tributaries including the Humbert River, Soda Springs Creek, Depot Creek and Broadarrow Creek and through one permanent waterhole, Johnston Billabong, before reaching its confluence with the Victoria River, south of the Fitzgerald Range near Pompey Knob. The Wickham River descends 256 metres (840 ft) over its 198-kilometre (123 mi) course.
The Wickham flows for only six months of the year, during the wet season. During the dry season, a string of waterholes form along the course of the river some of which are spring-fed and almost permanent.
