Flood Forecasting and Warning

Status: Water Safety Statement

Watershed Conditions Statement

Monday, April 3, 2017 (11:00 AM)

The Raisin Region Conservation Authority is advising caution near local rivers and creeks. Water levels are currently rising and water is moving quickly.

Long range forecasts are showing an accumulated precipitation total of 70mm or more over the next 5 days. Upper portions of the watershed still have significant snowpack. Combined runoff from the rainfall and snowmelt may cause ponding and potential for flooding in low lying areas.

Water is currently contained within the river banks for the most part, and wide-scale flooding is not expected.

The RRCA will continue to monitor the situation and post updates on this website and social media as conditions evolve.

 

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.
