Grand River Conservation Authority issues Flood Warning for the County of Brant

The Grand River Conservation Authority (GRCA) is updating and issuing a Flood Warning for the County of Brant, as well as Drayton, Grand Valley, Waldemar, West Montrose, the Village of Conestogo, New Hamburg, Ayr, Brantford and Six Nations. 

The Flood Watch previously issued for the remainder of the Grand River watershed remains in effect. For the full update visit the GRCA's website.

Flood Warning Message for County of Brant
River flows have reached flooding thresholds for low lying areas and walking trail systems along the Grand River in County of Brant. 

Properties adjacent to the Grand River are advised to closely monitor river levels, take the necessary safety precautions, and safeguard any items that could be exposed to flooding in the event that their property is impacted.

Weather forecast
Temperatures in the watershed have increased to double digits above freezing over Saturday, March 15, 2025, and have remained high throughout the weekend. A Colorado low system has moved across the watershed on Saturday and Sunday, bringing approximately 15 to 20 mm of rain along with sporadic thunderstorms. The snowpack in the northern part of the watershed still contains a significant amount of water content. Warm temperatures combined with rain, which may be heavy at times, is resulting in snowmelt and increased runoff. 

Stay safe 
The public is encouraged to exercise extreme caution around local waterways. Parents are reminded to keep their children and pets away from watercourses. The public is reminded to stay off ice-covered waterbodies, due to unsafe conditions. 

River conditions and forecasts are being monitored closely, and any additional flood messages will be issued as needed.
