Geography

The main watersheds near the Moncouche river are:

north side: Métabetchouane River, Huard lake and rivière à la Carpe;

The Moncouche River rises at the mouth of Starr Lake. This misshapen lake looks like a big X or a star; it has two large bays to the north, two in the center and two to the south.
From its source, the course of the Moncouche River descends on with a drop of, according these segments:

southward, to the northeast shore of Saint-Véran Lake;
to the southwest crossing Saint-Véran over its full length;
to the southwest crossing Moncouche Lake over its full length. Note: Saint-Véran Lake and Moncouche Lake are interconnected, thus providing for pleasure boating.
to the south, until the confluence of the rivière aux Montagnais ;
to the southwest, in particular by bypassing an island and crossing Lake Méandre, until it meets the Métabetchouane River.

From the confluence of the Moncouche river, the current descends the Métabetchouane River northward on to the south shore of lac Saint-Jean; thence, the current crosses the latter on towards the northeast, then follows the course of the Saguenay River via La Petite Décharge on to Tadoussac where it merges with the Saint Lawrence estuary.
