The rivière aux Ours is a tributary of the Sainte-Anne river flowing in the municipality of Saint-Raymond, in the Portneuf Regional County Municipality, in the administrative region of Capitale-Nationale, in Quebec, in Canada.
The small valley of the Rivière aux Ours is served by the Corcoran road and the Chute-Panet road which runs along the south and east bank of the Sainte-Anne river, for the needs of agriculture, forestry and residents of the sector.[1]
The main economic activities of the sector are agriculture and forestry.[1]
The surface of the Bear River (except the rapids areas) is generally frozen from the beginning of December to the end of March; however, safe circulation on the ice is generally from late December to early March. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.
Geography
The Bear River has its source at the mouth in a marsh area (length: 2.5 kilometres (1.6 mi); altitude 154 metres (505 ft)) located on the south side of the Pionniers Industrial Park at Saint-Raymond. This source is located at:
- 1.8 kilometres (1.1 mi) east of the course of the Sainte-Anne river;
- 3.4 kilometres (2.1 mi) south of the village center of Saint-Raymond;
- 4.0 kilometres (2.5 mi) north of the confluence of Rivière aux Ours and Rivière Sainte-Anne;
- 44.1 kilometres (27.4 mi) to the north, the confluence of the latter with the St. Lawrence River.[1]
From its source, the Bear River flows over 6.6 kilometres (4.1 mi) especially in forest areas, sometimes agricultural, with a drop of 25 metres (82 ft), according to the following segments:
- 1.7 kilometres (1.1 mi) especially in the marsh area, first towards the west, then towards the south, up to the Cormoran road bridge;
- 1.8 kilometres (1.1 mi) towards the southwest by crossing rue Germain, up to a bend in the river;
- 3.1 kilometres (1.9 mi) first towards the south-east by forming a hook (curving towards the east), collecting two discharges (coming from the east) from unidentified lakes and the discharge (via a small lake) (coming from the east) of Lac Plamondon, passing north of a hamlet, crossing route 354, then crossing two small unidentified lakes, until its mouth.[1]
The Bear River flows at the end of a bend on the south bank of the Sainte-Anne River. This confluence is located at:
- 6.3 kilometres (3.9 mi) upstream of the Ford Falls in Sainte-Christine-d'Auvergne;
- 4.1 kilometres (2.5 mi) downstream from the hamlet Chute-Panet in Saint-Raymond;
- 16.2 kilometres (10.1 mi) to the north-west of the St. Lawrence River;
- 7.1 kilometres (4.4 mi) south of the village center of Saint-Raymond;
- 40.2 kilometres (25.0 mi) north of the confluence of the Sainte-Anne river with the Saint-Laurent river.[1]
From this confluence, the current descends on 69.1 kilometres (42.9 mi) generally south and southwest following the course of the Sainte-Anne river, to the northwest bank of the Saint Lawrence river.[1]
Toponymy
The toponym "Rivière aux Ours" was formalized on August 17, 1978, at the Place Names Bank of the Commission de toponymie du Québec.[2]
