Rivière des Mares (Gouffre River tributary)
The rivière des Mares is a tributary of the west bank of the lower part of the Rivière du Gouffre, flowing entirely in the town of Baie-Saint-Paul, in the Charlevoix Regional County Municipality, in the administrative region of Capitale-Nationale, in the province from Quebec, to Canada. This valley is mainly served by the route 138 (boulevard de Monseigneur-De Laval) which runs along the west side of the Rivière du Gouffre, and the chemin de Louisbourg which partially goes up this valley. The intermediate and upper parts being mountainous have few  passable roads. Besides the agricultural area in the Gouffre river valley, forestry is the main economic activity in this valley. The surface of the Mares River is generally frozen from the beginning of December until the beginning of April; however, safe circulation on the ice is generally done from mid-December to the end of March. The water level of the river varies with the seasons and the precipitation; the spring flood generally occurs in April. Geography.

Toponymy. During the history, this river was designated under several names with several orthographic variations: Rivière à la Truite, Ruisseau des Marées, Rivière Lamarre, Rivière des Mars, Rivière de la Mare and finally Rivière des Mares. According to some research that the Commission de toponymie du Québec has learned about, the current official name may have originated in the former Domaine de la Mare à la Truite. The latter takes its name from a small body of water located at the bottom of the valley. The use  of the name "Rivière de la Mare" is old since it is found mentioned in the delimitation of the lands of Baie-Saint-Paul in 1716. The toponym "Rivière des Mares" was formalized on March 25, 1997 at the Place Names Bank of the Commission de toponymie du Québec.
