The Yamachiche River is a river located on the north shore of Lake Saint-Pierre in the Maskinongé Regional County Municipality, in the administrative region of Mauricie, in Quebec, in Canada. It originates in the Mastigouche Wildlife Reserve.
The Yamachiche River flows mostly in a wooded area north of Charette, and then generally in an agricultural environment on the rest of its course.
The main hydrographic slopes of the Yamachiche River are:
The main body of water at the head of the Yamachiche River is the "Great Long Lake" (length: 2.5 km (1.6 mi) oriented from north to south, altitude: 176 m (577 ft)) located in the municipality of Saint-Élie. He obtains water from three landfills:
Riverside downstream from Grand Lac Long
The Great Lake Long dump is located at the bottom of a bay south of the lake. From there, the Yamachiche River flows on: About 40 m in the "Petit lac Long" (length: 480 m, altitude: 176 m), which flows through 340 m west; 240 m by crossing under a road bridge to go into the Lake Perchaud (length: 1,4 km, altitude: 175 m); 860 m by crossing the lake at la Perchaud, from the north-west to the southeast. A dam has been erected at its mouth. The Lac à la Perchaude receives through its west point the waters of a series of lakes upstream on the north side: Lac des Chutes (length: 0.8 km that the current crosses over 0.6 km, altitude: 209 m) Lac Fer à Cheval (length: 1.0 km from one end to the other, altitude: 209 m), and Lake to the island (length: 1,6 km, altitude: 229 m).
In short, the Second Lac Raquette is the highest lake (233 m) of the watershed of the Yamachiche River; The second being the lake on the Island (229 m); the third being Bournival Lake (220 m).
The course of the river downstream from the lake to the perch
From the perch lake, the river descends 260 meters to the south and flows into Lake Garand (length: 1.2 km facing south, elevation: 172 m). Then the river descends 3.9 km southwest through the village of Saint-Élie to the mouth of the Paterson Lake Creek. From there, the river descends 4.7 km south to the limit of the municipality of Charette, Quebec.
