The rivière à Idas (English: Idas River) is a tributary of the north bank of the upper part of the Bras du Nord-Ouest, 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 of Quebec, in Canada.
This valley is mainly served by a forest road going up the right bank of the watercourse, as well as by the chemin du rang de Saint-Placide Sud. Forestry is the main economic activity in this valley; recreational tourism, second.
The surface of the river in Idas 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.
The Idas river rises at the mouth of Idas Lake (length: 0.7 kilometres (0.43 mi); altitude: 884 metres (2,900 ft)). The mouth of this landlocked lake is located at the bottom of a bay east of the lake, either:
- 2.2 kilometres (1.4 mi) west of a mountain peak (altitude: 982 metres (3,222 ft));
- 2.3 kilometres (1.4 mi) south-east of Montagne du Lac à Ange (altitude: 1,091 metres (3,579 ft));
- 5.1 kilometres (3.2 mi) north-east of a curve of the Sainte-Anne River;
- 10.8 kilometres (6.7 mi) north-west of the village center of Saint-Cassien-des-Caps located along route 138;
- 16.2 kilometres (10.1 mi) west of the northwest shore of the St. Lawrence River;
- 19.0 kilometres (11.8 mi) south of the mouth of the Bras du Nord-Ouest (confluence with the Rivière du Gouffre), or in downtown Baie-Saint-Paul.[1]
From this mouth, the Idas river descends on 8.4 kilometres (5.2 mi) perpendicular to the shore of the St. Lawrence River, with a drop of 482 metres (1,581 ft), according to the following segments:
- 1.1 kilometres (0.68 mi) north-east crossing to the southwest shore of Lac Gonzague (length: 0.5 kilometres (0.31 mi); altitude: 791 metres (2,595 ft)); then crossing the latter lake on 0.25 kilometres (0.16 mi) south-east to its mouth;
- 5.0 kilometres (3.1 mi) towards the south-east in a deep valley and forming a loop towards the south in the middle of the segment to go around a mountain, until the discharge (coming from the north) of a small lake;
- 2.3 kilometres (1.4 mi) towards the east in a less and less steep valley, forming some serpentines and cutting the path of Rang de Saint-Placide Sud, to its mouth.[1]
The Idas river flows on the north bank of the Bras du Nord-Ouest, in the city of Baie-Saint-Paul. This mouth is located at:
- 1.1 kilometres (0.68 mi) south of the village center of Saint-Placide-de-Charlevoix;
- 4.1 kilometres (2.5 mi) west of route 138;
- 2.2 kilometres (1.4 mi) north-west of the Saint-Jean mountain peak (altitude: 690 metres (2,260 ft));
- 11.1 kilometres (6.9 mi) north-east of the course of the Sainte-Anne River;
- 10.7 kilometres (6.6 mi) southwest of the mouth of the Bras du Nord-Ouest (confluence with the rivière du Gouffre), i.e. in downtown Baie-Saint-Paul;
- 9.5 kilometres (5.9 mi) west of the northwest shore of the St. Lawrence River.[1]
From the mouth of the Idas river, the current descends on 14.4 kilometres (8.9 mi) following the course of the Bras du Nord-Ouest; then on 3.2 kilometres (2.0 mi) with a drop of 6 metres (20 ft) following the course of the rivière du Gouffre which flows into Baie-Saint-Paul in the St. Lawrence River.[1]
