FLOOD WARNING DOWNGRADED: Saint Lawrence River
South Nation Conservation (SNC) has downgraded the Flood Warning for the Saint Lawrence River issued on May 17, 2019, to a Flood Watch.
There is a risk of severe thunderstorms and strong winds on Wednesday, August 21, 2019.
Lake Ontario’s water levels are declining, which will continue into the fall. Levels are still expected to remain near seasonal highs over the next several weeks.
Flooding and other high-water impacts continue to be reported around the upper Saint Lawrence River during periods of active weather.
The latest forecast from the International Lake Ontario – St. Lawrence River Board suggests that Lake Ontario’s water levels will continue to gradually decline throughout the summer into the fall, with the rate of decline largely depending on rainfall.
Lake Ontario’s increased outflows may increase Saint Lawrence River levels upstream of Iroquois throughout Edwardsburg/Cardinal and Augusta Township.
Residents are advised that wind may cause large waves, further aggravating water levels which may affect structures close to shore.
Residents in flood-prone areas are encouraged to closely monitor conditions and take necessary actions.
Residents are advised to stay away from watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain dangers to children.
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.
This Flood Watch statement is in effect until Friday, September 27, 2019 at 5:00 PM.
SNC monitors the water levels and weather forecasts as part of the Flood Forecasting and Warning Program. Updates are provided as conditions change.
The International Lake Ontario – St. Lawrence River Board continues to monitor conditions on an ongoing basis. Information on hydrologic conditions, water levels and outflows, including graphics and photos, are available on the Board’s website at www.ijc.org/en/loslrb.
