Warmer temperatures, snow melt and rainfall will maintain the current high water levels and may result in nuisance flooding in low-lying areas across the jurisdiction. Unstable ice conditions will also result from warmer temperatures and higher flows.


Residents are advised to exercise extreme caution when near rivers and waterbodies as the forecasted weather may rapidly increase river flows and cause slippery conditions. Parents are encouraged to explain these dangers to their children.

Residents in flood prone or low-lying areas, historically susceptible to flooding, should take the necessary precautions to protect their property. Please ensure:

·       sump pump is clear, in good working condition and has a backwater valve on it.

·       downspouts are clear and the outlet is at least 3 m from the dwelling.

·       easy access to portable backup generator and pump.

·       items that might float away as flows increase are secured.

·       valuable items are removed from basements or lower floors that could be subject to flooding.

This flood outlook statement is in effect until Tuesday, March 29th, 2022 at 5 PM or until an update has been issued.

SNC monitors the water levels and weather forecasts as part of the Flood Forecasting and Warning Program. Updates are provided as conditions change.
