Flood Forecasting and Warning

Status: Normal

Return to Normal

Thursday, May 11, 2017 (2:00 PM)

Watershed conditions have returned to normal within the Raisin Region Conservation Authority jurisdiction. We are not anticipating any significant rise in water levels due to the current precipitation forecast. Water levels along the St. Lawrence River from South Stormont through to the Quebec border are not expected to see significant changes due to operations at the Moses-Saunders Dam to reduce water levels on Lake Ontario.

 

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.
