Status: Flood Outlook Statement

The Raisin Region Conservation Authority (RRCA) is issuing a Flood Outlook Statement for the RRCA jurisdiction.

Daytime and overnight temperatures are likely to remain above freezing through the next four days. On Saturday, March 19, 20 mm of rain is forecast. Snowmelt will increase water levels and flows in all RRCA watersheds over the coming days. If rainfall occurs as forecast, water levels could reach their highest point of 2022 so far.

Currently, nuisance flooding of low-lying areas is expected. Water levels and flows may change rapidly. Take extra caution near waterbodies. 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 Monday, March 21, 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.

About Flood Forecasting and Warning in the RRCA

The Ontario Ministry of Natural Resources and Forestry (MNRF) is responsible for flood related emergencies. Flood forecasting and warning has been delegated to Conservation Authorities. If a local emergency is declared, MNRF will work directly with the municipality and in consultation with the Conservation Authority.

The Raisin Region Conservation Authority monitors precipitation and water levels throughout Cornwall, South Glengarry, and large portions of North Glengarry and South Stormont.
