The Catin river rises at the mouth of Lac à la Catin (length: 2.8 km (1.7 mi); altitude: 597 m (1,959 ft)) in a deep valley. This lake is surrounded by Mont du Saumon (816 m (2,677 ft)), Mont du Colibri (861 m (2,825 ft)) and Mont Pin (737 m (2,418 ft)). The mouth of this lake is located at:

• 2.3 km (1.4 mi) south-west of the center of the hamlet "Les Trois-Monts";
• 4.5 km (2.8 mi) north-west of the center of the hamlet "L’Épinglette-des-Lacs";
• 7.2 km (4.5 mi) north-west of "Lac Bazile";
• 9.5 km (5.9 mi) north of the course of the Malbaie River;
• 1.2 km (0.75 mi) south-east of the mouth of Brébeuf Lake;
• 13.8 km (8.6 mi) south-east of the confluence of the Catin river and the Cami River.

From its source, the course of the Catin river descends on 22.3 km (13.9 mi) in forest and mountainous areas, with a drop of 247 m (810 ft) according to the following segments:

Upper course of the Cami river (segment of 11.4 km (7.1 mi))

• 3.4 km (2.1 mi) to the northwest by collecting the outlet (coming from the northeast) from Lac Solitaire and the outlet (coming from the south) from Lac à Lionel, to brook Pin (from the southwest);
• 3.4 km (2.1 mi) towards the northeast crossing three zones of rapids, passing to the northwest of a mountain whose summit reaches 657 m (2,156 ft), turning a bend of river at the end of the segment, up to the outlet (coming from the south-east) of a mountain stream draining in particular the Mont de l'Ours (altitude:962 m (3,156 ft));
• 2.2 km (1.4 mi) towards the north almost always in rapids in a deep valley and forming a hook of 0.3 km (0.19 mi) towards the west, until the discharge (coming from the northeast) of a few lakes;
• 2.4 km (1.5 mi) westwards, to the outlet of "Lac de la Souris";

Lower course of the Cami river (segment of 10.9 km (6.8 mi))

• 4.1 km (2.5 mi) to the west, forming a large curve to the south, crossing an area of marsh, then a long area of rapids, up to the discharge (coming from the southwest) from the "Lac des Hauteurs";
• 3.0 km (1.9 mi) towards the north-west crossing several zones of rapids until a stream (coming from the east) which corresponds to a zone of marsh;
• 1.9 km (1.2 mi) north-west to the outlet (coming from the south) of "Lac Trouvé";
• 1.9 km (1.2 mi) towards the north-west entirely in the area of rapids in a steep valley, to its mouth.

The Catin river flows on the south bank of the Cami River. This confluence is located at:

• 0.8 km (0.50 mi) south of the confluence of the Cami River (confluence with the Saint-Jean River);
• 1.2 km (0.75 mi) south-east of the mouth of the Brébeuf Lake (confluence with the Saint Jean River);
• 14.9 km (9.3 mi) south-west of the village center of Rivière-Éternité;
• 27.1 km (16.8 mi) south-west of the confluence of the Saint-Jean River and L'Anse-Saint-Jean (Saguenay River);
• 5.4 km (3.4 mi) south of a bay on Éternité Lake;
• 49.1 km (30.5 mi) south-east of downtown Saguenay (city).

From the confluence of the Catin river, the current:

• follows the course of the Cami River on 1.0 km (0.62 mi) towards the North;
• follows the course of the Saint-Jean River (Saguenay River tributary) on 37.7 km (23.4 mi) generally towards the northeast;
• crosses L'Anse-Saint-Jean on 2.9 km (1.8 mi) to the north;
• follows the course of the Saguenay River on 42.8 km (26.6 mi) eastward to Tadoussac where it merges with the Estuary of Saint Lawrence.

The term "Catin" refers to a doll (toy) in French.

The toponym "Rivière à la Catin" was formalized on December 5, 1968, by the Commission de toponymie du Québec.[3]
