Watershed Conditions: Water Safety Statement

Tuesday, July 9, 2024. The Raisin Region Conservation Authority (RRCA) is issuing a Flood Watch for the RRCA jurisdiction. A Flood Watch is issued when flooding of infrastructure has not yet occurred but is possible under forecast weather conditions.

Weather Forecast: Heavy rainfall associated with the remnants of Hurricane Beryl are expected to reach eastern Ontario on Wednesday, bringing significant precipitation. Environment Canada forecasts 40 to 80 mm of rainfall with locally higher amounts possible.

Environmental Conditions: Water levels and flows are currently normal for this time of year in the RRCA jurisdiction in Eastern Ontario. The anticipated rainfall Wednesday continuing into Thursday morning will result in increased water levels and flows in rivers, similar to those observed during the Spring Freshet.

Risks: All rivers and streams across the jurisdiction may experience high water levels, fast flowing water and slippery or unstable banks. Flooding is possible in low lying areas.

In North Glengarry: High risk of water backing up in areas typically susceptible to spring flooding downstream of Mill Pond. The water levels of Loch Garry, Middle Lake, and Mill Pond are being actively managed. Sudden increases in dam outflow may be necessary under the forecast weather conditions.

Residents in areas regularly affected by spring flooding should take precautions to protect their property, such as:

• Securing items that might float away as flows increase.

• Removing items from sheds, garages, basements, or lower floors that could be subject to flooding.

• Ensuring sump pump is clear, in good working condition, and has a backwater valve.

• Ensuring easy access to a portable backup generator and pump.

This statement is in effect until Friday, July 12, at 11:00 AM. The RRCA will continue monitoring water levels and weather forecasts as part of the Flood Forecasting and Warning program. Updates will be provided as conditions change.
