Wednesday, March 11, 2026 (2:00 PM)
This statement is an update to the Flood Watch statement issued on March 10, 2026.
The Raisin Region Conservation Authority (RRCA) is issuing a Flood Warning for its jurisdiction.
Weather Forecast: Environment Canada is forecasting continued above-zero temperatures which will result in additional snowmelt across the region. Rainfall, heavy at times, is expected throughout the evening reaching up to 30mm by tomorrow.
Environmental Conditions: Recent warm temperatures, combined with precipitation, have led to significant snowmelt, causing rising water levels and increased flows. Many creeks in the RRCA jurisdiction are approaching bank full conditions.
Risks: Flooding is expected within the inland rivers throughout the RRCA jurisdiction. Low-lying roads, farm lanes, and driveways alongside rivers and creeks may be susceptible to flooding during the week.
South Glengarry:
Low-lying roads susceptible to flooding include:
- McGillivray Road between Martintown and County Road 27
- Chapel Road, between the Beaudette River and Caber Road
- River Road, between McGillivrays Bridge and Williamstown
- Cashion Road
- Loyalist Road, downstream of Williamstown
South Stormont:
Properties upstream of St. Andrews West on the Raisin River may experience high water.
North Glengarry:
The RRCA is actively monitoring and managing lake levels at Loch Garry, Middle Lake, and Mill Pond to reduce the potential for flooding. Water levels in the Garry River, downstream of these lakes, may rise suddenly as part of necessary water level management.
This statement remains in effect until Monday, March 16, 2026, at 4:00 pm. The RRCA will continue monitoring water levels and weather forecasts as part of its Flood Forecasting and Warning program. Updates will be provided as conditions change.
