After issuing a flood watch late Wednesday evening, the St. Clair Region Conservation Authority has upgraded the watch to a flood warning.
“Yesterday’s intense rain event brought 20 to 75 mm of rainfall across the region, with most areas reporting around 50 mm,” SCRCA officials stated on Thursday, April 3, 2025 at 1:56 p.m.
“An additional 15 to 25 mm of rain is forecast for tomorrow (Friday), with another 5 to 15 mm for Saturday. Water levels are continuing to climb from yesterday’s influx of water, which has led to widespread flooding of low-lying areas and some roads. Soils are saturated and will have little ability to absorb the additional rainfall forecast for the next two days, leading to increased runoff and water levels, as well as possible erosion and seepage issues.”
SCRCA officials added at present, the following roads are confirmed to be impacted by floodwater:
– Plowing Match Road between Petrolia Line and Rokeby Line
– Fairweather Road between Oil Springs Line and Aberfeldy Line
– Oakdale Road between Churchill Line and LaSalle Line
– Black Ash Road between Durham Creek and Aberfeldy Line
– Pretty Road between Stanley Line and McCallum Line
– Stanley Line between Waubuno Road and Kimble Road
“Individuals are reminded to avoid watercourses and flooded areas due to dangerous conditions, slippery banks, and cold, swift moving water,” stated Emily De Cloet, interim coordinator for flood forecasting and warning for the SCRCA, in a media release.
“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.”
This message will remain in effect until 12 p.m. on April 7, 2025, unless otherwise updated.
