The Grand River Conservation Authority has issued a flood warning for Brantford and Brant County as rising river levels and the risk of ice jams create hazardous conditions. The warning, which was put in place on April 1, 2026, comes after significant rainfall and warm temperatures over the last few days triggered a rapid snowmelt across the watershed.
Recent reports indicate that up to 60 mm of rain fell in the area over a 48-hour period, pushing river flows into a high-risk category. Authorities are concerned about the potential for ice jams, which can cause water levels to rise suddenly. In Brantford, areas near Gilkison Street and the Gilkison Flats trail system are particularly vulnerable, with trails in the flats already reported as flooded.
To help manage the situation, the conservation authority is currently utilizing its reservoir system to reduce the impact of the high water flow downstream. While the city’s dike system is designed to provide protection, local officials note that its capacity can be challenged during significant ice jam events, similar to major flooding incidents that occurred in 1996 and 2018.
The City of Brantford and the conservation authority are currently working on a Brantford Ice Jam Mitigation Class Environmental Assessment to find better ways to handle these flooding events in the future. The project is being supported by Montrose Environmental, and residents have until April 7, 2026, to provide feedback on the study. Residents are encouraged to stay away from riverbanks and remain alert to changing conditions while the flood warning remains in effect.
