Temperatures in the double digits are expected across the watershed from Saturday to Tuesday. This will cause most of the measured and modeled snow, which contains 100 mm of water, at the headwaters of the Moira and Salmon Rivers to melt.
This snowmelt has the potential to increase river flows to normal, spring high water levels late next week.
Areas that annually experience localized flooding will likely start to experience that again this spring.
Limited rain is predicted for the weekend.
Last week’s rainfall and snowmelt contributed to the rise in river levels with many areas reaching their peak.
Water Resources Manager, Christine McClure says, “The warming temperatures will cause exceedance of the peak water levels experienced this past week.”
The southern reaches of the Salmon River peaked on March 31; however, northern reaches of the Salmon River are continuing to slowly rise.
The Moira River at Tweed, the Skootamatta River, and the Black River all peaked on April 1.
The Clare River reached its peak on April 2.
The Napanee River reached its peak on April 3.
Although some rivers in the watershed have peaked, they will peak again with rising water levels.
Staff will continue to monitor conditions and will provide an update if forecasts and conditions change. For current water levels or to report any observations of flooding, residents are encouraged to visit
The public is reminded to stay off ice and avoid river banks and shorelines.
A Flood Outlook Statement gives early notice of the potential for flooding based on weather forecasts calling for heavy rain, snow melt, high wind or other conditions that could lead to high runoff, cause ice jams, lakeshore flooding or erosion.
This message will be in effect until (or updated if anything significant changes before) Monday, April 15, 2019.
