Warm temperatures and southerly winds earlier this week resulted in the deterioration of an ice bridge across Lake Huron at Sarnia, opening up the St. Clair River to ice movement. Winds have since shifted to the north and are currently pushing ice and flow into the St. Clair River, creating the potential for ice jamming and elevated water levels.

Water level readings at gauges on both the US and Canadian sides of the St. Clair River are beginning to indicate signs of flow restriction north of Port Lambton. Ice is anticipated to continue flowing into the river as northerly winds carry over into late Friday when they are anticipated to shift north-west.

Individuals are reminded to avoid 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 message will remain in effect until Saturday, February 5, 2022 at 12:00 unless otherwise updated.
