Flood Forecasting



Flood Forecasting

The CRCA monitors weather information, river flows, snow pack and ice conditions in order to predict when floods will occur and how high the water may rise. When flooding is possible, or about to occur, the CRCA issues flood messages to municipal emergency management officials and the media. In a flood emergency situation, municipalities take the lead as they are responsible for emergency response under provincial legislation. Each municipality has an emergency response plan which deals with many situations including flooding.

As a result of a review of flood message terminology, the CRCA and Conservation Authorities across the province are introducing some changes effective February 2012. These changes will ensure that Conservation Authorities use consistent terminology in line with that used by other agencies such as the Ontario Ministry of Natural Resources, Environment Canada and the Weather Network.
