The Piponisiw River is a tributary of Simard Lake located in the western part of the Gouin Reservoir, flowing entirely into the forest zone in the town of La Tuque, in the administrative region of Mauricie, Quebec, Canada. The Piponisiw River flows successively in the canton of Lacasse. Forestry is the main economic activity of this valley; recreational tourism activities, second. The Piponisiw River valley is served by the R1045 road that connects the R1009 forest roads on the west side of the Gouin Reservoir and the R2046 which leads south to the village of Obedjiwan, Quebec. This R1045 road bypasses the northern part of Irinikew Octikwan Lake, crosses the Piponisiw River south of the head lake and heads northeasterly to lake Lacasse and lake Masko Oponapananik. The surface of the Piponisiw River is usually frozen from mid-November to the end of April, however, safe ice circulation is generally from early December to late March.
