Davoust River

The Davoust River is a tributary of the northeast shore of the Nottaway River, flowing into the municipality of Eeyou Istchee Baie-James (municipality), in the administrative region of Nord-du-Québec, in Quebec, in Canada.

The Davoust River flows entirely in the forest and marsh zone at the East of Lake Dusaux, which is crossed by the Nottaway River. The surface of the river is usually frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.

A forest road passes on the East side of Mouliers Lake.
