Noire River (French: Rivière Noire, pronounced [ʁivjɛʁ nwaʁ]) is one of the main watercourses of the Sainte-Anne River (Les Chenaux) watershed, it measures 62 km in length, its watershed has an area of 568 km².

[3] The main sources of the Noire River are Long (Saint-Alban) and Clair (Sainte-Christine-d'Auvergne) lakes, it flows into the waters of the Sainte-Anne River in Saint-Casimir, Quebec municipality.

[2][4] The flora observed today in the territory of the Portneuf Regional Natural Park, and the portion of the Black River which flows there, does not represent the forest of the regional pre-industria eral.

A large part of the territory has been the subject of logging for more than 200 years.

So, the harvest of Tamarack (Red spruce) and Allegheny birch (Yellow birch) was done without concern for regeneration, between 1870 and 1890 the harvest of the bark of Canadian tsuga (Tsuga) for its tannery properties led to the modification of the composition of all the ecosystem.
