Rivière aux Rognons facts for kids

The Rivière aux Rognons (English: Kidneys River) is a tributary of the northeast shore of the Jeannotte River, flowing in the municipality of Lac-Édouard and the town of La Tuque, in the administrative region of Mauricie, in province, in Quebec, in Canada.

The course of the “Rivière aux Rognons” descends on the west side of the Batiscan River and on the east side of the Saint-Maurice River. This river is part of the hydrographic side of the Batiscan River which generally winds south to the north bank of the St. Lawrence River.

The course of the “Rivière aux Rognons” descends entirely into the forest zone in a territory considered to be an island, taking into account that lac Édouard (Quebec) has two outlets. This island is bounded by the Batiscan River (to the east), the Jeannotte River (to the west) and the Lake Édouard (Quebec) (to the north). The river surface is generally frozen from mid-December until the end of March.

Since the middle of the 19th century, forestry has been the predominant activity of the "Rivière aux Rognons" watershed.
