Ruisseau de la Martine
The ruisseau de la Martine ("English: Martine stream") is a tributary of the northwest shore of the St. Lawrence 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. This valley is served by rue Principale de Petite-Rivière-Saint-François, which runs along the Saint-Laurent river to the west of the mouth of the Martine stream and then goes up the latter valley and the river valley from Sault. 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 Massif of Charlevoix which is located very close to the south side of this river and whose flank the mountain for alpine skiing faces the river. The surface of the Martine stream is generally frozen from the beginning of December until the end of March, except the eddy areas; however, safe traffic on the ice is generally from mid -December to mid-March. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April. Geography. The Martine stream rises at a bend in the river where there is the confluence of the Sault river (coming from the east) and a stream (coming from the north), in the municipality of Petite-Rivière-Saint-François.

The Martine stream flows onto the northwest shore of the St. Lawrence River, on the "Pointe de la Rivière" (peninsula) in the hamlet Maillard, in the municipality of Petite-Rivière-Saint-François.

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. It refers to a sault which is defined as a more or less significant slope break or a fall. The toponym "Petite rivière Saint-François" was formalized on August 17, 1978 at the Place Names Bank of the Commission de toponymie du Québec.
