Watershed Conditions: Flood Outlook Statement - Update
March 24, 2023 (5:00 PM)
The Raisin Region Conservation Authority (RRCA) is updating the Flood Outlook Statement, issued March 20, for the RRCA jurisdiction. The expected timing of peak water levels has changed due to a change in the rainfall forecast.
The weather forecast is calling for further warm weather, and 15-20 mm of rain is expected on March 25-26.
Water levels and flows are elevated throughout the RRCA jurisdiction due to recent snowmelt, and water levels are expected to continue climbing through the weekend given the forecast rainfall. Flooding of low-lying areas normally water-covered in spring is possible: Watercourses are currently expected to reach their highest levels of February and March so far this year (however, water levels are not expected to exceed those of early January). The RRCA encourages residents to take extra caution near water bodies and secure items that may float away as water flows increase.
Water levels are currently expected to peak on March 27-28. Water levels are then expected to begin an overall decline through the following days.
This statement is in effect until Friday, March 31, 2023, at 4:00 PM. The RRCA will continue monitoring water levels and weather forecasts as part of the Flood Forecasting and Warning program. Updates will be provided as conditions change.
