The high temperatures of the past few days and the rain that will fall this week have led to minor flooding of some waterways, while others are under surveillance.

This is particularly the case of the Rivière du Nord, towards Saint-Jérôme, and the Rivière Ouareau, at the head of the Dorwin falls in Lanaudière, which have emerged from their beds.
We are talking about average floods. Water levels and flows at these locations will remain high for the next few days and the rain forecast for the next few days will cause further increases.
Lac des Deux Montagnes also overflows slightly in Sainte-Anne-de-Bellevue and Terrasse-Vaudreuil, where there is talk of minor flooding.
In Sainte-Anne-de-Bellevue, the trend is up, while water levels are down for Terrasse-Vaudreuil.
Minor flooding was also noticed at Lake Maskinongé in Saint-Gabriel-de-Brandon, the Chaudière River in Saint-Lambert-de-Lauzon, the Mille Îles River in Deux-Montagnes, the Ottawa River in Ottawa. and Rigaud Bay, Diable River, North River near Sainte-Agathe-des-Monts, L’Assomption River in Joliette, and Black River in Sainte-Émélie-de-l ‘Energy.
