It joins the Tsolum River to form the Courtenay River, which enters the Strait of Georgia at the city of Courtenay.

The river was officially named by Robert Brown of the Vancouver Island Exploring Expedition in 1854, after the people who lived along it, although Lieut.
Mayne of the Royal Engineers had noted the name Puntluch River.
