Monitoring - Flooding
Current Status – April 17, 2026 (PM)
The Organisation municipale de sécurité civile of Ville de Vaudreuil-Dorion (OMSC) met again late this afternoon to review the current flood situation.
The Fire Department continues to closely monitor conditions by conducting patrols in areas considered to be at higher risk. At this time, the situation across the Vaudreuil-Dorion territory is under control.
According to the latest information published by the Centre d’expertise hydrique du Québec (MELCCFP), the water level of lac des Deux Montagnes is expected to reach 23.63 m today, 23.71 m tomorrow, and 23.81 m on Sunday. For comparison, levels reached 24.63 m in 2019, 24.66 m in 2017, and 24.33 m in 2023. For more details, visit their website.
The OMSC is currently at Yellow Level (alert mode). On the ground, the Service des travaux publics is carrying out various interventions, including the installation of a dike at the end of Hôtel-de-Ville Street, deployment of auxiliary pumps and water-filled barriers, as well as monitoring patrols. Additional equipment is expected tomorrow morning and will be installed over the weekend.
The City invites residents to remain attentive to upcoming communications and to follow the evolution of the situation through its official platforms. Residents are encouraged to register for the Citizen Space to receive important updates quickly (phone call, email, or text message).
