The Jean-Pierre River flows successively into the townships of Dansereau, Bureau and Leblanc, south of the Gouin Reservoir and on the west side of the upper Saint-Maurice River. Forestry is the main economic activity of this valley; recreational tourism activities, second.

The route 405, connecting the Gouin Dam to the village of Wemotaci, Quebec by the west bank of the Saint-Maurice River, serves the Jean-Pierre River Valley and also the peninsula that stretches north on 30.1 kilometres (18.7 mi) in the Gouin Reservoir. Some secondary forest roads are in use nearby for forestry and recreational tourism activities.

The surface of the Jean-Pierre River is usually frozen from mid-November to the end of April, however, safe ice circulation is generally from early December to late March.

Geography
The adjacent hydrographic slopes of the Jean-Pierre River are:

The Jean-Pierre River originates at the mouth of Machinila Lake (length: 0.5 kilometres (0.31 mi); altitude: 500 metres (1,600 ft)). The mouth of this lake head is located at:

  • 4.2 kilometres (2.6 mi) south-east of the mouth of the Jean-Pierre River (confluence with Jean-Pierre Bay of Gouin Reservoir);
  • 22.0 kilometres (13.7 mi) south of the dam at the mouth of the Gouin Reservoir (confluence with the Saint-Maurice River);
  • 40.9 kilometres (25.4 mi) north-east of the village center of Wemotaci, Quebec which is located along the Saint-Maurice River;
  • 132 kilometres (82 mi) north-west of downtown La Tuque.[2]

From the mouth of the head lake, the course of the Jean-Pierre River flows over 23.4 kilometres (14.5 mi) according to the following segments:

  • 5.1 kilometres (3.2 mi) north-east, then north across Lac Jean-Pierre (length: 2.3 kilometres (1.4 mi); altitude: 474 metres (1,555 ft)) on its full length, to its mouth. Note: Lake Jean-Pierre straddles the townships of Dansereau and Bureau;
  • 3.3 kilometres (2.1 mi) north across Lake Sylvain (length: 1.0 kilometre (0.62 mi); altitude: 474 metres (1,555 ft)) on its full length, then the Minister's Lake (length: 3.9 kilometres (2.4 mi); altitude: 465 metres (1,526 ft)) on 1.8 kilometres (1.1 mi), to its mouth;
  • 4.0 kilometres (2.5 mi) northwesterly to the mouth of Lake Peter (length: 2.9 kilometres (1.8 mi); altitude: 425 metres (1,394 ft)) that the current crosses over a hundred meters;
  • 3.2 kilometres (2.0 mi) north-east between the mountains, to the outlet of South Lake (coming from the East);
  • 7.4 kilometres (4.6 mi) southwesterly, passing between two mountains, cutting a forest road, then crossing a lake (length: 3.5 kilometres (2.2 mi); altitude: 413 metres (1,355 ft)) formed by a widening of the river, to the eastern limit of the township of Leblanc;
  • 0.4 kilometres (0.25 mi) northwesterly in the Township of Leblanc to its mouth.[3]

The confluence of the "Jean-Pierre River" with the Gouin Reservoir is located at:

  • 11.7 kilometres (7.3 mi) south-west of Gouin Dam;
  • 66.4 kilometres (41.3 mi) south-east of the village center of Obedjiwan, Quebec;
  • 56.0 kilometres (34.8 mi) northwest of the village center of Wemotaci, Quebec;
  • 144.7 kilometres (89.9 mi) north-west of downtown La Tuque;
  • 251 kilometres (156 mi) northwest of the mouth of the Saint-Maurice River (confluence with the St. Lawrence River at Trois-Rivières).

The Jean-Pierre River flows on the eastern shore of Jean-Pierre Bay (length: 7.9 kilometres (4.9 mi) advancing south), straddling the townships of Aubin and Leblanc. From this mouth, the current flows northward on 7.4 kilometres (4.6 mi) through Jean-Pierre Bay; then, the current flows eastward on 12.0 kilometres (7.5 mi) across the Kikendatch Bay to the Gouin Dam. From there, the current flows along the Saint-Maurice River to Trois-Rivières, where it flows on the North Shore of the St. Lawrence River.
