This short river of 26 km rises in the Mékinac Lake and flows south to throw in the Saint-Maurice River in north of Saint-Roch-de-Mékinac. The mouth is located almost opposite the Mekinac island near the west bank of the Saint-Maurice River. The Mekinac river flows especially in agricultural areas and sometimes in forest. The river pass through the village of Saint-Joseph-de-Mékinac. This river has many rapids, making it navigable for shallow-draft, especially in the Spring and only in certain segments outside periods of major floods. The river is usually frozen from December to late March, except in some areas of strong rapids. A dam of 6,8 m. managed by Hydro-Québec is held at the mouth of Mékinac Lake. While the discharge of Missionary Lake flows into the Mékinac Lake, near the dam.
In its descent, the Mekinac river receives on its right bank the water of the stream Dumont, and on its left bank streams Thom (taking its source at Lake Thom, George, to Bouchard and Le Jeune) and Vlimeux (taking its source at Lake Vlimeux). Mekinac river flows along the northern boundary of Lejeune township, in the northern part of the municipality of Sainte-Thècle.
The road linking the village of Saint-Joseph-de-Mékinac and the mouth of the river Mekinac, is located on the south side of the River.
