The Flood Watch issued by South Nation Conservation on July 9, 2024, has been downgraded to a Water Safety Statement.
Weather Forecast:SNC’s climate stations received between 30 and 50 mm of rain between Tuesday and Thursday morning and rainy conditions are expected to end Thursday afternoon.
Environmental Conditions:Water levels and flows remain elevated and are expected to decrease in the coming days.
Risks:All rivers and streams across the jurisdiction may experience higher water levels, fast flowing water and slippery or unstable banks.
ACTION: Residents are advised to exercise extreme caution when near rivers and waterbodies due to high river flows and slippery conditions. Parents are encouraged to explain these dangers to their children.
Residents in flood prone or low-lying areas, historically susceptible to flooding, should take the necessary precautions to protect their property. Please ensure:
- Sump pump is clear, in good working condition and has a backwater valve on it.
- Easy access to portable backup generator and pump.
- Downspouts are clear and the outlet is at least 3 m from the dwelling.
- Securing items that might float away as flows increase.
Duration:This water safety statement is in effect until July 15th, 2024, at 5 PM or until an update has been issued.
SNC monitors the water levels and weather forecasts as part of the Flood Forecasting and Warning Program. Updates are provided as conditions change.
Raisin Region
Ahead of expected heavy rain on Wednesday, July 10, and Thursday, July 11, the Raisin Region Conservation Authority (RRCA) issued a Flood Watch for its entire jurisdiction. The current hazard level has been set at orange, which is the category below the most hazardous red level. 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 is expected to reach eastern Ontario on Wednesday, bringing significant precipitation. Environment Canada forecasts 40 to 80 millimetres or 1.7 to 3 inches 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 the 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.
