Flood Forecasting and Warning

Status: Normal

Flood warning ended

Saturday, April 8, 2023 (4:00 PM)

Status: Normal

The Raisin Region Conservation Authority (RRCA) has ended the flood warning issued on April 6, 2023.

Water level remain high, but are subsiding across the RRCA's jurisdiction, and are now at or below flood threshold levels. No rain is forecast for the coming week. Dams on the Garry River system continue to be actively managed. It is expected that lake inflows will soon decline sufficiently to allow outflow from Mill Pond to be reduced. 

Caution is still advised as water levels and flows remain high across the region. If you encounter flooded roadways, do not drive through floodwaters: Water can hide flood damage to the road, which could include washed-out sections of road. Strong currents can sweep vehicles off roadways.

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.
