Geography

The main watersheds neighboring the Métabetchouane Est river are:

north side: Métabetchouane River, Rivière aux Écorces du Milieu;

The Métabetchouane Est River takes its source at the mouth of "Lac des Hautes des Terres". Enclosed between mountains, this lake is linked on the north side by a small stream with the "Lac de la Hauteur" which turns out to be the head lake of the rivière aux Écorces du Milieu. The mouth of "Lac des Hauts des Terres" is located: south of the source of the source of rivière aux Écorces du Milieu, at northwest of Lac Chagnon, northeast of Lac Tentant and northeast.
From its source, the course of the Métabetchouane East river descends on, with a drop of, according to the following segments:
Upper course of the Métabetchouane East River

southwards crossing on Lake Mousseau, then Lake Aramis, to the outlet from Lakes Athos and Porthos;
to the south, forming a large S, up to the outlet of Lac Bourbier;
towards the west by forming a hook towards the south and meandering, until the outlet of lakes Fretin, Tentant and Petit lac Tentant;
north-east, to the outlet from Lake Sigma;
to the west, collecting the outlet from Lac des Margouilies, and branching northwest to the Gratia stream ;
south-east, then south by collecting the discharge from Badaillac, Lime and Frêle lakes, to the north shore of Missip lake;

Intermediate course of the Métabetchouane East river

to the west, sometimes winding and collecting the discharge from the Nourrains and Bocage lakes;
south-west, then north-west, up to Maria stream ;
north-west, up to a bend in the river;
south-west, to the outlet from lakes Boisseau, Dunoyon and Étang Florissant;

Lower course of the Métabetchouane Est river

first on towards the south-west in a deep valley up to a bend of the river; then on towards the south-east, then the south-west, up to the Liane stream ;
towards the southwest by forming a large S, crossing a few series of rapids then forming a loop towards the southeast, until the outlet from the Lake Raidillon;
to the southwest by forming serpentines at the end of the segment near a marsh area, until it meets the Métabetchouane River.

From the confluence of the Métabetchouane East river, the current descends the Métabetchouane North River on to the south shore of lac Saint-Jean; from there, the current crosses the latter on towards the northeast, then borrows the course of the Saguenay River via La Petite Landfill on until Tadoussac where it merges with the Saint Lawrence estuary.
