Residents along Laval’s waterfront are preparing for more flooding with water levels in the Mille-Îles River, Rivière des Prairies and Lac des Deux Montagnes expected to rise.
A possible 20 millimetres of rain, Monday's high temperatures and lingering surface ice on both rivers and Lac des Deux Montagnes have public safety authorities watching water levels around Laval closely.
They are likely to rise on Monday, says Const. Nathalie Lorrain of the Laval police.
Some flooding is already evident in streets and on properties along the rivers, but houses have been spared so far, Lorrain said.
More water is also coming Laval’s way via the Outaouais River, which is running high. The river flows into Lac des Deux Montagnes, which feeds both the Mille-Îlles River and Rivière des Prairies.
Adding to the flood risk in Laval is river ice that refuses to melt, which Lorrain said is unusual for this time of year.
Water is flowing under the ice, which could lead to ice-jams and flooding when the ice does break.
To help residents prepare, Laval’s emergency coordination authorities have set up 15 locations in the city where bulk sand is available for filling sandbags.
Empty sandbags are available at local fire stations.
Laval residents with questions about flood preparations are encouraged to call 311.
Anyone with a flooding emergency is asked to call 911.
