On March 7, 2026, the Grand River Conservation Authority kept Brantford, Ontario, under a flood watch as warmer weather creates unstable river conditions. This alert follows a rise in temperatures that is causing snow to melt quickly and run off into the river system.
While Brantford is currently under a watch, the conservation authority has issued a more serious flood warning for New Hamburg, Ayr, and West Montrose. A flood watch means that flooding is possible, while a warning indicates that flooding is imminent or already occurring in those specific areas.
The main concern for local officials is the potential for ice jams. As the ice on the river breaks apart due to the melt, the floating chunks can get stuck and block the flow of water, leading to unpredictable and rapid flooding in low-lying areas.
Residents are advised to stay away from the banks of the Grand River and avoid all activities on the ice. The City of Brantford and local emergency teams are monitoring the situation and will provide updates if any parks or riverside roads need to be closed for safety.
