Flood Status

ISSUED OCT 30, 2019 @ 3:15PM
Flood Potential: Low

The Ganaraska Region Conservation Authority advises that rainfall in the amount of 30 to 50mm is forecast to begin this evening and continue through the day tomorrow.

Watersheds within the Ganaraska Region are wet and local rivers and creeks are currently flowing slightly above normal due to recent rainfall. With the bulk of the rain forecast for Thursday afternoon and evening, it is expected that stream levels will be rising during this period with high flows continuing overnight. All water bodies, including ponds, streams and many ditches will be flowing higher than normal.

Strong and gusty winds are also expected during this potent fall storm, which may result in high waves along the shorelines of Lake Ontario and Rice Lake.

While no flooding is anticipated, high flows at this time of year can still be dangerous. Slippery stream banks and fast flowing, colder water will create hazardous conditions around all bodies of water. As a result, local streams and rivers may become dangerous, especially in the vicinity of culverts and bridges. Children should be warned to stay away from all watercourses and shorelines.

This Watershed Conditions Statement will be in effect through Friday, November 1st, 2019. Conservation Authority staff will continue to monitor watershed conditions and provide updates as necessary. Should you have any questions or wish to report flooding, please contact the following GRCA staff at 905-885-8173.
