The lower part of this small valley is served by chemin de l'Abitibi-Price, chemin du rang Saint-Marie and chemin Clairval. Chemin du rang Saint-Édouard runs southwest of the middle part of the river course. The upper part is served by a secondary forest road passing on the north side of the river and which connects to the southeast with the Abitibi-Price road. Forestry is the main economic activity in this valley; recreational tourism, second. The surface of the lower part of the Mont Saint-Étienne river is generally frozen from the beginning of December until the end of March; however, safe traffic on the ice is generally from mid-December to mid-March. The upper part has a freezing period of about an additional week. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.
