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;

• 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.

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

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 there, the current flows along the Saint-Maurice River to Trois-Rivières, where it flows on the North Shore of the St. Lawrence River.
