Geography
edit
The Trois Saumons river takes its source from Trois Saumons lake (length: 5.5 kilometres (3.4 mi); altitude: 434 metres (1,424 ft)), located in the municipality of Saint-Aubert. This recreational and tourist-oriented lake, with a significant density of chalets on its banks, is surrounded by forest. This head lake is located 9.4 kilometres (5.8 mi) southeast of the south shore of the St. Lawrence River, 6.2 kilometres (3.9 mi) south of the center of the village of Saint-Aubert and at 9.0 kilometres (5.6 mi) northeast of the village center of Saint-Cyrille-de-Lessard. Trois Saumons Lake flows through its northeast end.[1]
From its source, the Trois Saumons River flows over 17.0 kilometres (10.6 mi), divided into the following segments:
- 2.1 kilometres (1.3 mi) north-west, crossing the fifth rang East road in Saint-Aubert up to the Bélanger road;
- 3.0 kilometres (1.9 mi) towards the north-west, to the confluence of the Trois Saumons East River (coming from the east);
- 3.7 kilometres (2.3 mi) heading west, crossing rue Principale Ouest (and route du third rang west), to the limit between Saint-Aubert and Saint-Jean-Port-Joli;
- 3.2 kilometres (2.0 mi) northwesterly, up to highway 20;
- 5.0 kilometres (3.1 mi) heading west, crossing the railway line and cutting route 132, to its confluence.[1]
At the end of its course, the Trois Saumons River flows onto the long shore (at low tide) in the Anse de Trois-Saumons, on the south shore of the middle estuary of the St. Laurent. This confluence is located 2.6 kilometres (1.6 mi) north-east of the village of L'Islet-sur-Mer and 6.8 kilometres (4.2 mi) to the south-west of the village of Saint-Jean-Port-Joli.[1]
