Flooding | Update as of April 23

Overall Situation

Water levels appear to have plateaued, and forecasts indicate that they will begin to recede starting tomorrow. At this time, the situation in the Vaudreuil-Dorion area is under control. The Service de sécurité incendie is maintaining a watch and conducting regular patrols in areas deemed at risk.

No Facebook posts are planned in the coming days, barring any major developments. We strongly recommend signing up for the Citizen Space to stay informed.

Actions taken and ongoing

• Installation of a levee on Saint-Charles Avenue, between Turcot and Brabant Streets;
• Installation of a levee on Chemin des Chenaux, near the overpass;
• Implementation of preventive measures to protect sensitive infrastructure—including sewer access manholes and pumping stations—to limit the impacts of a potential rise in water levels. 

Guidelines for the public

Even though the situation is stable, it is strongly recommended that protective measures remain in place. Any cause for concern can be reported to municipal authorities.

Closures

• A section of Rue de Breslay, which runs parallel to Highway 40, is closed.
• The Esther-Blondin Pier is closed to the public.
• The road leading to Maison-Valois Park is closed.

Residents can also view the forecasts using the Crues Grand Montréal tool.

Please note that this tool does not take into account flood control measures implemented by the City (levees, flood barriers, etc.). The data comes from water level gauges located along the main waterways of the metropolitan archipelago and is updated in near real time. 72-hour forecasts are also issued every six hours. However, these forecasts involve a degree of uncertainty and are provided for informational purposes only.

Self-service sand stations

The City provides self-service sand stations for residents to help them protect their property.

Sandbag filling stations are now available. Facilities have been set up on-site to make filling the bags easier.

Important: Residents must bring their own shovel.

Residents who wish to obtain bags, “Tyrap”-type ties, and polyethylene sheeting for the construction of levees should go to the municipal workshops (205 Valois Street), following the on-site signage. The workshops are open Monday through Friday, from 7:00 a.m. to 11:45 a.m. and from 12:30 p.m. to 3:15 p.m. 

Station locations

Two sites are currently available:

• 190 Saint-Charles Avenue, at the corner of Hôtel-de-Ville Street (Vieux-Dorion neighborhood) 

• Corner of Breslay Street and Chenaux Road

These locations were selected based on their accessibility and the available space to ensure smooth and safe traffic flow.
