A Flood Watch Statement indicates that flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individual landowners in flood prone areas should prepare.
Weather Forecast: The remnants of Hurricane Beryl are expected to reach Ontario on Wednesday, bringing significant precipitation. The forecast rainfall amounts vary among the weather guidance products at this time. The widespread rainfall amounts will most likely be from 50 mm to 60 mm.
Watershed Conditions: Water levels and flows are high across the MVCA jurisdiction due to the continued rain events in June/July.
Risks: Dalhousie Lake water levels are expected to reach spring flood conditions. Levels are expected to increase 20 to 25 cm above current elevations should the rain forecasted for tomorrow materialize. Water levels on Mississippi Lake are also expected to increase 15 to 20 cm above current levels based on current forecasted conditions. Levels on the upper lakes have been holding steady or dropping slowly over the last week but are expected to begin to increase again should the forecasted rain occur.
Actions: Residents in flood prone areas are advised to maintain close watch on water levels and flows and take the necessary precautions to protect their property by:
• Ensuring sump pumps are clear, in good working condition and have a backwater valve.
• Having a portable generator and backup pump available.
• Ensuring downspouts are clear and the outlet is at least 3 meters from any structure.
• Removing or securing items that might float away if flows increase.
• Keeping emergency phone numbers handy.
• Familiarizing yourself with your municipality’s emergency preparedness plan.
Duration: This message is in effect until July 16, 2024 or until an update has been issued.
For More Information: Daily water levels and flows are available on the MVCA website at www.mvc.on.ca/water-levels.

Newsrooms please note:
A Watershed Conditions Statement is NOT a flood warning. Its purpose is to raise public awareness about a change or potential change in watershed conditions.
See below for watershed conditions terminology:
Watershed Conditions Statement: General notice of weather conditions that could pose a risk to personal safety or which have the potential to lead to flooding. There are two variations of these:
- Water Safety Statement: High flows, unsafe banks, melting ice or other factors could be dangerous for recreational users such as anglers, canoeists, hikers, children, pets, etc. Flooding is not expected.
- Flood Outlook Statement: Early notice of the potential for flooding based on weather forecasts calling for heavy rain, snow melt, high wind or other conditions that could lead to high runoff, cause ice jams, lakeshore flooding or erosion.
Flood Watch: Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individual landowners in flood-prone areas should prepare.
Flood Warning: Flooding is imminent or already occurring in specific watercourses or municipalities. Municipalities and individuals should act to deal with flood conditions. This may include road closures and evacuations.
