Ice jamming on the St. Clair River led the St. Clair Region Conservation Authority (SCRA) to issue a flood watch on Wednesday, February 3, 2021.
SCRCA officials say strong winds are anticipated and there is a potential for shoreline erosion and minor flooding.
“Strong northerly winds over recent days have resulted in the movement of ice from Lake Huron into the St. Clair River,” SCRCA officials said in a media release.
“The Canadian Coast Guard is reporting an active ice jam on the St. Clair River at Port Lambton, with two ice breaking vessels currently active in the area to Algonac, Michigan. Additional ice breaking vessels are en route to further ice breaking efforts.”
SCRCA officials added: “Winds are anticipated to shift to the south overnight, with wind speeds increasing throughout Thursday to gusts of 50-60 km/h in the evening. Forecasts are further indicating winds may become southwesterly and gust between 60-70 km/h beginning early Friday, continuing through the day. These winds may impact the movement of ice and could exacerbate water levels. Residents along the St. Clair River may experience minor flooding and possible shoreline erosion from the ice jam and winds.”
Residents are reminded to avoid shorelines, watercourses and flooded areas due to dangerous ice conditions, slippery banks and swift moving water, SCRCA officials say.
“Children and pets should be kept away from the water,” SCRCA officials added.
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, SCRCA officials say.
This message will remain in effect until Friday, February 5, 2021, unless otherwise updated.
