  • Upwards of 100 mm of rain in the past 24 hours
  • Additional 20-40 mm of rain expected in the next 12 hours
  • Water levels rapidly rising, potential for impacted roads

Gauges within the watershed are reporting upwards of 100 mm of rain since yesterday. An additional 20-40 mm of rain is anticipated over the next 12 hours.

Water levels are rising quickly and breaching bankfull limits. The upper reaches of the Sydenham River are anticipated to peak early Thursday morning, followed by mid-watershed areas late Thursday morning to mid-afternoon. As the water moves through the system, water levels in the lower reaches near Dresden and Wallaceburg are anticipated to peak late Thursday evening.
The following roads are anticipated to be impacted by flooding:

  • Stanley Line between Kimball Road and Waubuno Road
  • Pretty Road north of McCallum Line
  • Waterworks Road north of Courtright Line

Residents are reminded to avoid shorelines, watercourses and flooded areas due to dangerous conditions, slippery banks and cold, swift moving water. 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 remains in effect until Friday.
