The river flows west until discharging into Arurine Bay near Dongara.
The river passes through the Coalseam Conservation Park to the north of Mingenew which has a mixed geology of siltstones, claystones and sandstones that form stripes in the cliff faces formed by the river.
The river occasionally floods as it did in 1945 following a severe storm that swept over the area.
The river broke its banks and caused extensive damage including the loss of 450 sheep that were swept away from a farm that straddled the river.
