Flood Message Definitions

Provincial flood messages

There are 2 types of provincial flood messages:

  • the Provincial Watershed Conditions Statement, which provides information on provincial watershed conditions as they relate to flood potential, and an outlook on expected spring flood conditions

There are 3 types of local flood messages:

  • flood warning: flooding is imminent or already occurring

Who to contact for flood information

Your local Conservation Authority is responsible for local flood messaging.

Your local municipality is responsible for on-the-ground flood response.

If you live in a community that is not serviced by a conservation authority, any flood watches or flood warnings in your area are issued by the nearest Ministry of Natural Resources and Forestry district office.
