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 water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.

The Sault river rises at the mouth of a small lake (length: 1.4 kilometres (0.87 mi); altitude: 684 metres (2,244 ft)), on the north side of a summit of mountain in the municipality of Petite-Rivière-Saint-François.

[1] This river is designated "Rivière du Sault" (today "Ruisseau de la Martine") by the cartographer Joseph Bouchette, on his topographic maps of 1815 and 1831.

The acronym "Ruisseau du Sot" later becomes usage to designate this watercourse; this variant reflects the spelling used in Bouchette's time.
