Weather Forecast:

Environment Canada is forecasting milder temperatures throughout the week, reaching daytime temperatures of 8 oC, and periods of rain towards the end of the week and into the weekend totaling up to 17 mm by Saturday, March 26th. 

Environmental Conditions:

Increased runoff is expected to continue due to warmer temperatures, melting snow, and forecasted rainfall. The increased water levels and flows resulting from last weeks warmer temperatures are expected to continue across the SNC jurisdiction. Ice breakup has also begun throughout the jurisdiction and is expected to continue. 

Spring flooding is currently affecting the following roads resulting in road closures: 

  • Nation Municipality:
    • Concession Road12 West of County Road 9 from civic number 4330 up to
      Scotch River Road
    • River Bank Road, from civic number 3930 to 2833
    • Concession Road12 East of County Road 9
    • Lefebvre Road 
  • Township of Alfred and Plantagenet:
    • Concession Road 4 from 1183 m East of County Road 19 to Route 16
    • Concession Road 7 from 1040 m East of Station Road to St Jean Road
    • Concession Road 9 from Russell Road to 1148 m East of Russell Road
    • Concession Road 10 from 393 m West of County Road 19 to end of road 
  • City of Ottawa:
    • Bridge at Ray Wilson Road in Kenmore 

More information on road closures available at www.municipal511.ca.   

Risks:

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. 

ACTION:

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. 

Duration:
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.
