Following a rainy start to spring and rapid snowmelt, water levels on the Ottawa River are stabilizing.
According to the Ottawa River Regulation Planning Board (ORRPB), water levels at Lake Deschenes measured at 60.15 m on Friday. That level is expected to remain the same throughout the weekend.
In Gatineau, the Ottawa River is expected to retreat slightly. On Friday, levels measured at 44.3 m but are expected to decrease by 10 cm by Monday.
Snowmelt continues in the northern part of the watershed which will continued to pass increased flows downstream. As a result, water levels in Pembroke are expected to increase 5 cm over the weekend.
Unpredictable weather over the next week could result in a second flood peak from Pembroke to the Montreal Region.
“A rapid melt combined with rainfall could lead to water levels higher than those observed between April 19 and 22 in all locations,” the ORRPB said.
Gatineau residents receiving aid
The City of Gatineau said approximately 486 buildings have been affected by flooding with 190 buildings that could currently be flooded.
As a result, 12 people have voluntarily evacuated their homes and 109 people have received services from the Red Cross.
At this time, all evacuations are voluntary, but the city said staff are ready to support anyone who wishes to leave their home.
“Although water levels appear to be stabilizing, municipal crews are continuing to keep a close eye on the territory,” Gatineau Mayor Maude Marquis-Bissonnette said. “Levels are still high, and we are still vulnerable: keep the dykes in place to protect your homes.”

Freshet peaks at 2023 levels
The City of Ottawa says the first freshet peaked at, or slightly below, 2023 levels. However, staff say ongoing monitoring is needed as the situation evolves.
“Minor flooding levels have been exceeded in low-lying areas that are typically prone to flooding,” city staff said. “Major flood levels have been exceeded at many locations between Lac Coulogne and near the Montreal area.”
Boaters are asked to stay off the river in and around areas impacted by flooding.
Boating can cause further damage to homes and flood barriers as wakes crash against the shoreline. Floating debris, partially submerged debris, and fast-moving waters are also hazards for boaters.
The Emergency Coordination Centre has been activated and is monitoring conditions. There are currently 15 sandbag filling stations open across the city to help property owners if needed.
