The Rivière des Monts (English: River of the Mounts) is a tributary of the southwest bank of the lower part of the watercourse Le Gros Bras, flowing in the non organized from Lac-Pikauba and the municipality of Saint-Urbain, in the Charlevoix Regional County Municipality, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada.

The lower part of this valley is mainly served by a few forest roads which connect to the north with the Parc-des-Grands-Jardins road. The upper part of this valley is served by a few other forest roads which also serve Lac Chambers and Lac Carbonel to the south. Forestry is the main economic activity in this valley; recreational tourism, second.

The surface of the lower part of Le Petit Bras 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 upper part of this stream 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 generally occurs in April.

Geography

The Rivière des Monts rises at the mouth of a small lake (altitude: 796 metres (2,612 ft)) located in a forest area in a valley between Lac Saint-Denys (located on the north side) and the Thomas-Fortin Lake (located on the southwest side). This source of the river is located at:

0.7 kilometres (0.43 mi) east of the limit of Lac-Pikauba and Saint-Urbain;
8.4 kilometres (5.2 mi) east of the course of the upper part of the Malbaie River;
18.1 kilometres (11.2 mi) north-west of the village center of Saint-Urbain;
17.2 kilometres (10.7 mi) north-west of the mouth of Le Gros Bras (confluence with the Gouffre river);
29.6 kilometres (18.4 mi) north-west of Baie-Saint-Paul town center.^[1]

From its source, the course of the Monts river descends on 8.6 kilometres (5.3 mi) in a generally deep valley, with a drop of 467 metres (1,532 ft), according to the following segments:

3.1 kilometres (1.9 mi) first towards the south-east in a plain, then towards the north-east in an increasingly deep valley, until the discharge (coming from the south-west) from Lac Michel and Plaisant Pond;
0.6 kilometres (0.37 mi) east in a deep valley, to the outlet (coming from the northwest) from Lac à Moïse;
3.0 kilometres (1.9 mi) north-east to a bend in the river; then south-east in a deep valley, to a stream (coming from the south-west);
1.9 kilometres (1.2 mi) towards the east, passing on the north side of Mont du Gros Ruisseau, to its mouth.^[1]

The Rivière des Monts flows on the southwest bank of the Le Gros Bras stream, in the municipality of Saint-Urbain. This mouth is located at:

0.1 kilometres (0.062 mi) southwest of route 381;
2.9 kilometres (1.8 mi) south-west of Lac des Cygnes;
11.6 kilometres (7.2 mi) north-west of the village center of Saint-Urbain;
18.5 kilometres (11.5 mi) west of the village center of Saint-Hilarion;
24.3 kilometres (15.1 mi) north-west of Baie-Saint-Paul town center.^[1]

From the mouth of the Monts river, the current descends on 9.5 kilometres (5.9 mi) following the course of Le Gros Bras towards the south- East; then on 25.3 kilometres (15.7 mi) with a drop of 56 metres (184 ft) following the course of the rivière du Gouffre which flows into Baie-Saint-Paul in the St. Lawrence River.^[1]
