The American River is a tributary of the Jacquot River flowing in the municipality of Sainte-Christine-d'Auvergne, in the MRC Portneuf Regional County Municipality, in the administrative region of Capitale-Nationale, in Quebec, in Canada. Forestry is the main economic activity in the sector; recreotourism activities, second. The surface of the American river (except the rapids zones) is generally frozen from the beginning of December to the end of March; however, safe circulation on the ice is generally done from the end of December to the beginning of March.
