The Ottawa River in the Ottawa-Gatineau area is expected to see rising water levels this week, according to the Ottawa River Regulation Planning Board. The board issued a warning on Tuesday, April 29, 2026, stating that water levels are projected to increase on Thursday. This comes as a rainfall warning has been issued for the Ottawa region, with forecasts calling for 30 to 50 millimeters of rain tonight and into Thursday.
Rainfall Warning and Flood Risk
Environment Canada has issued a rainfall warning for Ottawa, predicting significant precipitation that could exacerbate the rising river levels. The heavy rain, combined with already elevated water levels, poses a risk of localized flooding in low-lying areas. Residents are advised to monitor conditions and take precautions to protect property.
Preparations Underway
Local authorities are preparing for potential flooding by deploying sandbags and monitoring water levels closely. The Ottawa River Regulation Planning Board continues to assess the situation and will provide updates as necessary. The public is urged to stay informed through official channels and avoid areas prone to flooding.
This weather event follows a pattern of spring thaws and heavy rainfall that often leads to increased river flows in the region. Similar warnings have been issued in past years, highlighting the need for ongoing vigilance.
