Flooding possible with coming rain and freezing rain

February 17, 2026

THE ST CLAIR REGION CONSERVATION AUTHORITY HAS ISSUED A FLOOD ALERT

Message: Rain and Melting Snow Expected to Raise Water Levels  

Warmer weather and rain over the next several days will cause water levels in local rivers and streams to rise.  

A weather system is moving through the area and will stay for most of the week, bringing with it 20 to 35 mm of rain and above-freezing temperatures.

Most of the rain is forecast for late Tuesday and all throughout Wednesday.   Right now, there is still a lot of frozen water held in the snow on the ground. The ground is saturated and has little ability to soak up more water. This means rain and melting snow will quickly run off into local watercourses.

Water is expected to overflow into low-lying areas that usually flood in the spring. High water levels will likely last through next week.  

Municipal staff should monitor local conditions closely, with special attention to known local drainage problem areas.

Many rural areas have had drifting snow, which can fill in ditches and smaller watercourses, blocking drainage during a runoff event and increasing flooding potential.  

Individuals are reminded to avoid watercourses and flooded areas due to dangerous conditions, slippery banks, unsafe ice cover and cold, swift moving water. Children and pets should be kept away from the water.  

The Conservation Authority continues to monitor watershed conditions and will issue advisories to municipalities and media should flood issues arise. Municipal emergency response staff and road superintendents should monitor local conditions closely.
