Preventing and Protecting Against Flooding

Our role is to protect people and property from flooding. We work to prevent or minimize the impacts of flooding by:

We review development proposals and support decisions that safeguard people and property while protecting natural features. While we can’t prevent flooding from occurring, keeping people and property out of flood-prone areas helps ensure naturally-occurring floods don’t contribute to local emergencies.

We operate a network of 59 real-time monitoring stations throughout the Credit River Watershed, strategically placed to send vital information about current environmental conditions. This allows us to best understand, predict and warn about flooding, threats to water quality and low water levels.

Flood Warning Messages

When flooding is possible or about to occur, we issue flood warning messages to municipal emergency management officials and the media about the potential threat to people and property. Municipal officials then take action to warn residents and provide emergency services as needed.

These messages can be found on our homepage, Facebook account and Twitter account.
