The only tributary of the river is the 7.5-kilometre (4.7 mi) Beaufort River East that joins the main river just east of where it crosses Albany Highway.
The river's catchment falls within the Blackwood catchment's Beaufort zone as part of the Beaufort system. The system is composed of broad valley floors with a grey sandy duplex and was previously a wandoosheoak[5] woodland but has now mostly been cleared for agriculture.
