The City of Gatineau says more buildings than previously forecasted may be at risk of flooding as water levels continue to rise in the Ottawa and Gatineau rivers.

“It is now estimated that approximately 41 streets could be affected by flooding, while 164 buildings are at risk, according to current forecasts,” the city said in the news release, translated from French.

Previous projections estimated that 119 buildings and 33 streets were at risk of by flooding.

“Municipal crews remain fully mobilized and are monitoring the area,” the city said. “In addition, representatives from the fire department are continuing to conduct home visits to properties located in areas likely to be affected.”

Maude Marquis-Bissonnette, the Mayor of Gatineau, says the city expects a water level increase of 30 centimetres in east Gatineau.

“Our teams have gone door to door making sure that people who are directly affected by the water are aware,” Marquis-Bissonnette said.

Marquis-Bissonette says sandbags are available 24/7 at the following locations:

• Parc Louis-Roy (5 rue Louis-Roy, Aylmer)
• Parc du Lac-Beauchamp (745 boul. Maloney-Est, Gatineau)
• Parc Jack-Eyamie (40 rue du Bassin, Masson-Angers)
• Parking lot of Saint-Jean-de-Brébeouf Community Centre (70 rue Moreau, Gatineau)

Ottawa River forecast

A flood warning is in effect along the Ottawa River from Arnprior to Pembroke. From Arnprior to Hawkesbury, a flood watch is in effect.

According to the Ottawa River Regulation Planning Board’s latest river conditions forecast, water levels continue to rise along the Ottawa River due to rainfall and snowmelt, though they may begin to stabilize on Monday.

“Over the next two weeks, levels are expected to plateau or slowly decline depending on weather,” the forecast states. “Risk of further increase in levels over coming weeks is higher from Mattawa to Lake Coulonge given the high snowpack remaining in the northern part of the basin.”
