SOUTH DUNDAS — This statement is an update to South Nation Conservation’s (SNC) Flood Watch: St. Lawrence River issued on May 9.
South Nation Conservation (SNC) continues to caution residents along low-lying areas of the St. Lawrence River in the Township of Augusta, Township of Edwardsburgh/Cardinal, and the Township of South Dundas. St. Lawrence River water levels are slowly declining, but are expected to remain high over the coming weeks due to high water levels in Lake Ontario and the forecasted 10-15 mm of precipitation this weekend.
According to the International Lake Ontario – St. Lawrence River Board: “Levels of Lake St. Lawrence, immediately upstream of Moses-Saunders Dam, have begun to decline as a result of recent flow increases. In response, gates at the Iroquois Dam (which had previously been lowered to suppress high levels on Lake St. Lawrence following recent flow reductions) were repositioned on May 10 and they will continue to be adjusted as outflows from Moses Saunders continue to increase over the coming days.”
Residents are also advised that wind may cause higher waves, further aggravating water levels which may affect structures closer to the shore.
Residents are advised to stay away from watercourses where flows are high and where banks might be unstable. Parents are encouraged to explain these dangers to their children.
Staff will continue to monitor the water levels and weather forecasts as part of the Flood Forecasting and Warning Program and will provide updates in the event conditions change.
The public is encouraged to visit www.nation.on.ca and to also report changes in water-related conditions, soil stress fractures (i.e. cracks in soil), abrupt changes in streambanks, or sudden leaning of trees in their local areas. All feedback and photos can be sent to email@example.com, posted on our Facebook page (/SouthNationConservation), or Tweeted to us (@SouthNationCA).
