Geography

The Rivière des Iroquois draws its head water from an agricultural area north of Chemin Saint-André, in the Saint-Luc sector, at Saint-Jean-sur-Richelieu.

This river flows northeast of the city of Saint-Jean-sur-Richelieu on:

  • 4.0 km north-west at the limit of the agricultural zone, to the route 104 connecting the Saint-Luc sector to the town of Laprairie;
  • 3.0 km north-east at the edge of the agricultural area, crossing the "Club de golf des Légendes" up to autoroute de la Vallée-des-Forts that the river crosses south of Chemin Saint-André;
  • 2.3 km towards the south-east, zigzagging in an agricultural area until it meets a small stream coming from the north;
  • 0.8 km south across route 223, to its mouth.[1]

In short, the upper part of the Iroquois river surrounds the urban area of the Saint-Luc sector.

The Iroquois River flows onto the east bank of the Chambly Canal, located on the west side of the Richelieu River, opposite the Île Sainte -Thérèse, at the northern limit of the urban area of Saint-Jean-sur-Richelieu.
