Highlights:

• McKeough Dam in operation
• Upwards of 100mm received over the last 48 hours
• Strong winds and wave action
• Road Closures

Significant amounts of rainfall have been received over the last two days, ranging from 30-100mm in areas. A further 5mm of rain and 1cm of snow is anticipated into tonight and early morning. Water levels elevated from rainfall earlier in the week are expected to rise further, with the potential for localized flooding in floodplain areas, parks and farm fields. At 8:50 pm the criteria for operation of the McKeough Dam was reached and the gates have been closed to reduce any potential flooding in Wallaceburg.

Soils are expected to be saturated from the rain and could contribute to ponding, increased runoff into watercourses, and possible increased erosion and seepage issues. High amounts of rainfall in a short period of time can lead to increased runoff and flash flooding, particularly in urban areas.

Strong winds of 50 to 60 Km/h from a southwesterly becoming westerly direction may impact Lake St. Clair. Residents along this shoreline may experience wind-driven high water levels and wave action, with a potential for erosion. Winds from a westerly direction are also anticipated to cause a backwater effect in the Wallaceburg area, slowing the flow of water out of the Sydenham River and contributing to elevated water levels.

The following roads will be impacted by high water levels:

St. Clair Township:

• Stanley Line east of Kimball Road
• Pretty Road north of McCallum Line

Enniskillen Township:

• Durham Creek Line at Black Ash Line
• Fairweather Road Between Rokeby Line and Shiloh Line
• Fairweather Road between Oil Springs Line and Aberfeldy Line

River banks are expected to be slippery, with possible minor erosion. Residents are reminded to avoid watercourses and flooded areas due to 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 message will remain in effect until Saturday, November 2, 2019 unless otherwise updated.
