Lac aux Montagnais

The Lac aux Montagnais is a freshwater body at the head of the rivière aux Montagnais, in the unorganized territory of Lac-Jacques-Cartier, in the La Côte-de-Beaupré Regional County Municipality, in the administrative region of Capitale-Nationale, in the province, in Quebec, Canada. "Lac aux Montagnais" is located in the northwestern part of the Laurentides Wildlife Reserve.

Lac aux Montagnais is located between route 169 (connecting Quebec (city) to Alma) and route 155 (connecting La Tuque and Chambord). A forest road bypasses the northern part of the lake. Some secondary forest roads serve this area for forestry and recreational tourism activities.

Forestry is the main economic activity in the sector; recreational tourism, second.

The surface of "Lac aux Montagnais" 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.

Toponymy
The specific term “Montagnais” designates one of the indigenous nations of the Algonquian family in eastern Canada, today known as “Innu”. Before the arrival of the first French settlers, the Innu occupied a huge territory of 600 km in depth extending, on the north bank of the St. Lawrence River, the city of Quebec (city) at Labrador Sea. On the south shore, their territory included the hydrographic basins of the Rivière du Loup and the Matane River. Already in 1892, the surveyor Henry O'Sullivan described the lake in these terms: “Lac Montagnais. It is a magnificent sheet of water with a circumference of more than six miles. Well provided with spotted trout ”. Today, permanent installations welcome vacationers, hunters and fishermen to this lake formerly frequented, no doubt, by the Innu in the vicinity of Lac Saint-Jean.

The toponym lac aux Montagnais was formalized on December 5, 1968, by the Commission de toponymie du Québec.
