Water levels and flows along the Ottawa River have stabilized, with only small amounts of snow remaining in the northern part of the basin. Water levels are expected to remain elevated over the coming weeks, and the river will remain sensitive to widespread rainfall events.
Current forecasts indicate that water levels will stay well below 2023 peak levels, with minor flood levels exceeded from Pembroke to Hawkesbury, but peak levels expected below major flood thresholds.
Elevated water levels are forecasted to remain relatively stable, with gradual declines possible starting next week.
This advisory includes flood-prone areas at Lake Coulonge, Chats Lake, Britannia / Lac Deschênes, Pointe-Gatineau, Cumberland, Rockland, and Hawkesbury.
Residents in flood-prone areas are encouraged to monitor conditions and continue necessary precautions:
• Ensure sump pumps are clear, in good working condition and have a backwater valve.
• Maintain easy access to a portable backup generator and pump.
• Keep downspouts clear and directed at least 3 m away from homes.
• Confirm driveway culverts are clear of debris and draining well.
• Secure loose items that could float away as flows increase.
The Mississippi Valley, Rideau Valley, and South Nation Conservation Authorities continue to monitor conditions alongside the Ministry of Natural Resources under Ontario’s Flood Forecasting and Warning Program. Updates will be provided as conditions change.
