Lac Grandbois is a freshwater body straddling the municipalities of Rivière-à-Pierre (southern part of the lake) and Saint-Raymond (northern part of the lake), in Portneuf Regional County Municipality, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada. Lac Grandbois proves to be the main head of the Noire River.
The west side of the lake is served by a forest road linking north the main street of Rivière-à-Pierre; the east side is served by a forest path linking south the Petit-lac-Batiscan path which runs along Perron stream.[1]
Forestry is the main economic activity in the sector; recreational tourism, second. This lake is located on the east side of zec Batiscan-Neilson and on the south side of the territory of Portneuf Wildlife Reserve.
The surface of Lac Grandbois is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally made from mid-December to mid-March.
