Rivière à la Tortue

The "rivière à la Tortue" takes its source at the mouth of "Lac à la Tortue" (northern part of the lake which is located in Hérouxville). The southern part of this lake is located in the Lac-à-la-Tortue sector of Shawinigan.

From the "Lac à la Tortue", the river turns a priori towards the northeast. It subsequently crosses:

• rang 10 of Hérouxville, on 0.7 kilometres (0.43 mi), to cross the road of the Grande-Ligne which constitutes the line of separation of the seigneuries of Batiscan and of Champlain;
• rang Saint-Pierre (south-west) of Hérouxville on 1.3 kilometres (0.81 mi). Tributary: Drouin and Brouillette watercourse (comprising the Adam-Cossette branch);
• rang Saint-Pierre (north-east) of Hérouxville for 2.4 km in a straight line (or 3.1 km following the course of the river), where the river makes a large curve to the right in heading southeast. Then, the course of the river enters in Saint-Narcisse, by the northwest end (range "Côte St-Pierre - Coté Nord-Est"), where it crosses four lots, on 1.4 kilometres (0.87 mi), measured by following the course of the river. Tributary: Bordeleau and Jacques watercourse;
• rang Saint-Paul (south-west side) Saint-Sévérin, on 4.6 km in a direct line (or 5.8 km following the course of the river). Tributaries: discharge from the Rang Saint-Pierre bay, Delfi and Ayotte rivers (including the Lafrance branch);
• rang Saint-Paul (northeast) in Saint-Sévérin, 1.9 km in a direct line (or 2.3 km following the course of the river). Tributary: Lépine stream. The Turtle River cuts Côte Saint-Paul Road approximately 3.2 kilometres (2.0 mi) southeast of the Côte Saint-Louis intersection;
• Saint-Louis concession (southwest), 1.2 km in a direct line (1.7 km following the course of the river), on lots 158–159. The river intersects Chemin Saint-Louis about 0.6 kilometres (0.37 mi) from the intersection of route 159;
• the southwest range of the Envies river in Saint-Stanislas, 2.8 km in a direct line (4 km following the route). Tributaries: Brûlé stream (lot 280) and Gignac stream (lot 288).

Finally, the river flows into the Rivière des Envies in Saint-Stanislas, near the current bridge of the route 159, at 3, 5 km from the mouth of the Envies river.

The Turtle River sub-basin is located between that of Rivière des Envies (to the northeast) and that of River des Chutes (to the southeast ). The distance in a direct line, between its source and its mouth, is 14 km (or 20.4 km following the course of the river).[1]

The toponym "Rivière à la Tortue" is directly associated with the name of head lake, ie "Lac à la Tortue". The toponym "Rivière à la Tortue" was registered on December 5, 1968 in the Bank of Place Names of Quebec of the Commission de toponymie du Québec.[2]
