The Moncouche Lake is a freshwater body of the watershed of the rivière aux Sables, flowing in the unorganized territory of Mont-Valin, in the Le Fjord-du-Saguenay Regional County Municipality, in the administrative region of the Saguenay–Lac-Saint-Jean, in the province of Quebec, in Canada. Most of the area is included in the northwestern part of the territory of zec Martin-Valin, in the township of Garreau. Forestry is the main economic activity in the sector. Recreational and tourist activities come second.
The forest road R0208 (North–south direction) serves the eastern side of Lac Le Marié and the upper part of Rivière aux Sables. In contrast, on the east side, the forest road R0201 (north–south direction) serves the valley of the Saint-Louis River. A few other secondary forest roads serve the vicinity of Lake Moncouche for the purposes of forestry and recreational tourism activities.
The surface of lake Moncouche is usually frozen from the end of November to the beginning of April, however the safe circulation on the ice is generally made from mid-December to the end of March.
