Lac à la Carpe

The lac à la Carpe (English: Carp Lake) is the most important freshwater body on the hydrographic side of the rivière à la Carpe on the watershed Lac Saint-Jean, in the unorganized territory of Belle-Rivière, in the Lac-Saint-Jean-Est Regional County Municipality, in the administrative region of Saguenay–Lac-Saint-Jean, in the province of Quebec, in Canada.

Lac à la Carpe is located a few kilometers from the northern limit of the Laurentides Wildlife Reserve.

This small valley is served by the forest road along the east bank of the Métabetchouane River. A few secondary roads serve this area for the needs of forestry, recreational tourism activities.

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

The surface of Carp Lake is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally done from mid-December to mid-March.
