Flood Outlook Statement Extended

Status: Flood Outlook Statement

The Raisin Region Conservation Authority (RRCA) is extending the Flood Outlook Statement first issued on March 16 for the RRCA jurisdiction.

Rainfall and snowmelt rapidly increased water levels over the weekend of March 19-20. Nuisance flooding occurred and continues to occur in many low-lying areas. Water levels are now slowly declining in RRCA watersheds. This decline is expected to continue over the next two days. However, rainfall forecast for Thursday, March 24, and Friday, March 25, is expected to increase water levels once again. This rainfall may return water levels to those of Sunday, March 20.

Currently, nuisance flooding of low-lying areas is expected. Any decline in water levels over the coming days may be reversed by the expected rainfall. If they have not done so already, residents in areas regularly affected by spring flooding should take precautions to protect their property, such as:

  • Ensuring sump pump is clear, in good working condition, and has a backwater valve
  • Ensuring easy access to a portable backup generator and pump
  • Ensuring downspouts are clear, with outlets at least 3 metres away from the building
  • Securing items that might float away as flows increase

This statement is in effect until Friday, April 1, 2022, at 12:00 PM. The RRCA will continue monitoring water levels and weather forecasts as part of the Flood Forecasting and Warning program.

A Flood Watch or Flood Warning Statement will be issued if the possibility of flooding becomes significant, or imminent, respectively.
