The Bédard River rises at Lac Déry (length: 0.6 km (0.37 mi); altitude: 176 m (577 ft)) in the municipality of Larouche. This source is located at:

From its source (Lac Déry), the Bédard River flows over 30.9 km (19.2 mi) with a drop of 79 m (259 ft) generally in agricultural area, sometimes forest, according to the following segments:

• 8.0 km (5.0 mi) westwards, up to the Petite rivière Bédard (coming from the south-east);
• 1.8 km (1.1 mi) westward, to the Canadian National Railway located in the village of Hébertville-Station;

• 6.5 km (4.0 mi) towards the northwest by crossing the road from 6e rang Ouest, to the "Route du Lac Ouest";
• 5.0 km (3.1 mi) towards the northwest by forming a few small streamers and cutting Scott Street West at the end of the segment, to the mouth of the river.

The course of the Bédard River flows onto the south bank of the Saguenay River in la Petite Décharge segment. This confluence is located at:

• 3.1 km (1.9 mi) east of the confluence of Lac Saint-Jean and the Saguenay River (i.e. at the entrance to the la Petite Décharge);

From the mouth of the Bédard River, the current follows the course of the Saguenay River for 139 m (456 ft) east to Tadoussac where it merges with the Saint Lawrence estuary.

"This river, sectioned in different places, has its source in the Kénogami horst and flows into the Little Landfill". The toponym “Bédard river” evokes “a certain Bédard” who “would have drowned there during a log drive”. The tragic event would have occurred before 1864, "because the river bears this name on a plan of the survey made that year. According to an eyewitness to the accident, this Bédard, having fallen into the water, had set foot on a rock in a fast and managed to stick to it for some time ”. We could not reach it, the waters being too high. "The accident took place at the confluence of two branches of the river, on lot 17 of range VI". The acronym also appears in Langelier, Jean-Chrysostome. The Lac Saint-Jean region, 1888, page 18. The name appears on the map of the township of La Barre (1st impression from 1892, last impression from 1943).

The toponym “Bédard River” was formalized on December 5, 1968, at the Place Names Bank of the Commission de toponymie du Québec.
