# Chaude River (Portneuf River tributary)

The Chaude River is a tributary of the Portneuf River, flowing in the municipalities of Portneuf, Sainte-Christine-d'Auvergne and Saint-Basile, in the Portneuf, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada.
Apart from the passage of the river near the village of Saint-Basile, the Chaude river flows mainly in agricultural and forestry areas, being the main economic activities of this small valley.
This small valley is served by chemin du rang Saint-Georges, rue Saint-Georges, boulevard du Centenaire, chemin du rang Sainte-Anne, route Côme-Lavallée, chemin du rang des Alain, route Saint-Joseph, the Misaël-Matte road and the 1st rue du Domaine-Allouette. The upper part is served by Chemin du Grand Rang, Chemin du Rang de la Montagne and Chemin de Bourg-Louis.
The surface of the Chaude River (except the rapids areas) is generally frozen from the beginning of December to the end of March; however, safe circulation on the ice is generally from late December to early March. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.

## Toponymy

The term "hot" in the Canadian toponymy for watercourses generally refers to sources of water that inhibit the formation of ice in winter on the surface of the watercourse.
The toponym "Rivière Chaude" was formalized on December 5, 1968, in the Place Names Bank of the Commission de toponymie du Québec.
