The rivière Wessonneau du Milieu is a tributary of the Wessonneau North River, in the town of La Tuque, in the region of Mauricie, in the province of Quebec, in Canada. Since the middle of the XIXth Century, forestry has been the main economic activity in this sector. At XXth Century, recreational and tourist activities have been highlighted, because the territory has been integrated into the zec Wessonneau. Some forest roads serve this valley for forestry and recreational tourism purposes. The water surface is normally frozen from beginning of December to end of March; however, safe traffic on the ice is usually from mid-December to the middle of March.
