Intense Rainfall Causes Flooding on Multiple Quebec Rivers

Quebec officials have reported flooding on a handful rivers north of Montreal and in Quebec City after heavy downpours fell on parts of the province this week.

In St-Jérôme, Que., roughly 50 kilometres northwest of downtown Montreal, water flow above 260 cubic metres per second led the province’s Public Security Department to categorize flooding on the Rivière du Nord as “major” on April 13 morning. Officials recorded a flow of around just 64 cubic metres per second on the same river three days earlier.

The department noted “medium” flooding on another four rivers and minor flooding around six other water level monitor stations in the province, including one in the St-Charles River west of downtown Quebec City.

But most reports of flooding were concentrated in Quebec’s Laurentides and Lanaudière regions north of Montreal, which received 30-35 millimetres and 35-40 millimetres of rain, respectively, between April 11 and April 13, Environment Canada meteorologist Félix Biron said.

The rural municipality of Chertsey, Que., 45 kilometres north of St-Jérôme, said in Facebook posts on April 13 that torrential rainfall had washed out part of a local roadway, submerging two vehicles and cutting some 50 residents off from the rest of the town.

Provincial police spokesperson Ève Brochu-Joubert said the two occupants of one of the vehicles escaped unharmed. Authorities were initially unable to locate the driver of the second vehicle, but later found the individual safe and sound.
