Rivière du Sault (Charlevoix)

The rivière du Sault (English: Sault River) is a tributary of the west bank of the ruisseau de la Martine on the northwest bank of the Saint-Laurent river. This river flows in the municipality of Petite-Rivière-Saint-François, in the Charlevoix Regional County Municipality, in the region Capitale-Nationale, in the province of Quebec, in Canada.

The route 138 runs along the west side of the upper part of this small valley. While the main street of Petite-Rivière-Saint-François descends the mountain on the northeast side of the course of this river. The economic activities of this valley are concentrated on the bank of the river where recreational tourism activities (notably vacationing) are developed. In addition, the peaks and flanks of the surrounding mountains are used for recreational tourism activities, in particular the important alpine ski center of the "Massif de Charlevoix" which is located very close to the east side of the upper part of this river and whose side of the mountain built for alpine skiing faces the river.

The surface of the lower part of the Sault River is generally frozen from the beginning of December until the end of March, except the backwater zones; however, safe traffic on the ice is generally from mid-December to mid-March. The upper part has an additional week's freezing period. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.
