Quality of water

Lake St. François

One of the most important resources in Saint-Anicet is Lake St. François, the name given to the larger part of the St. Lawrence River located between Salaberry-de-Valleyfield and Akwesasne.

Our lake is around fifty (50) kilometres in length and eight (8) kilometre-wide in certain places. A large part of the lake overlaps the Quebec and Ontario borders.

Blue-green algae

The cyanobacteria can be found on the surface of water, in large quantity, and looks like a slimy green foam.

If you think there is blue-green algae near the banks of the Lake, follow these recommendations from the ministère de la Santé et Services sociaux du Québec:

  • Avoid direct and prolonged contact with the algal bloom;
  • Avoid swimming or any other nautical activity in the area.

A simple, single contact with the water or splatter is enough to become a health hazard.

Aquatic activities can be resumed in the area where the algal bloom appeared 24 hours after it disappeared.

If you see large quantities of blue-green algae, please communicate with the bureau régional du Centre de contrôle environnemental du Québec at 450 534-5424.

Water analysis

If you wish to have the water of your well or the lake analyzed, the Municipality can provide you with water analysis kits that you can then send to the Notreau/Géostar Inc. laboratory. For more details, please communicate with city hall, or directly with Notreau/Géostar Inc. at 1 888 533-9996.

During the summer, you can consult the water analysis of the Saint-Anicet beach and other areas along Lake St. François.
