Flood warning for upper St. Lawrence River region

Expect flooding conditions.

EASTERN ONTARIO – The South Nation Conservation Authority (SNC) released an updated flooding warning on Friday, May 31, suggesting that predicted rainfall may increase St. Lawrence River water levels this weekend.

With a possibility of 15 to 25 mm of rain accumulation late Saturday, June 1 into Sunday, June 2, Lake Ontario’s increased outflows may increase the River levels, especially upstream of Iroquois throughout Edwardsburg/Cardinal and Augusta Township.

Lake Ontario’s water levels have reached the record peaks observed in 2017 and are expected to slowly continue rising,” read an SNC press release. “Peak levels will likely exceed those experienced in 2017 within the next several days.”

The flood warning will be instated until Friday, June 7. The peak seasonal level is expected to slowly decline in about three weeks time.

“Residents are advised that wind may cause large waves, further aggravating water levels which may affect structures close to shore,” read an SNC press release. “Residents are advised to stay away from watercourses where flows are high and where banks might be unstable…residents in flood prone or low-lying areas historically susceptible to flooding are encouraged to closely follow evolving conditions and take necessary precautions to protect their property.”

SNC monitors weather conditions and provides updates as they change. More information on water outflows and levels can be found by clicking here on the International Lake Ontario – St. Lawrence River Board website.
