A weather system is forecast to move through the Grand River watershed beginning Tuesday, April 2 through to Wednesday, April 3, bringing above freezing temperatures and approximately 40 to 50 mm of rain resulting in increased river flows throughout the watershed.

No significant flooding is expected with this event. However, river flows in local waterways will be higher than normal for this time of year, increasing the risk in low-lying areas typically prone to flooding. 

GRCA reservoirs

GRCA reservoirs are at their normal operating level for this time of year and will be operated to manage runoff and reduce downstream flooding. River flows will remain elevated, increasing the safety risk around rivers and streams throughout the watershed.

Stay safe 

The public is encouraged to exercise extreme caution around all local waterways. Banks adjacent to rivers and creeks are very slippery and, when combined with cold, fast-moving water, pose a serious hazard. Parents are encouraged to keep their children and pets away from all watercourses.

River conditions and weather forecasts are being monitored closely. This message will remain in effect until noon on Friday, April 5, 2024.  Updated flood messages will be issued as needed.
