The headwaters of the river lie below the Watrara Range near Island Hill and flows eastward until it discharges into Lake Dora. The river is unique in the region as it is a major watercourse with reliable water sources and many permanent pools.
The river has a total of nine tributaries including; Watrara Creek, Rooney Creek, Poonemerlarra Creek and Dunn Creek.
The river was named by the explorer Frank Hann in 1896 after the surveyor William Frederick Rudall whom he met in the area while Hann was prospecting and Rudall was searching for men missing from the Calvert Expedition. The traditional owners of the land are the Warnman peoples who call the river Karlamilyi.
