Flood Message Definitions

Provincial flood messages

There are 2 types of provincial flood messages:

  • the Provincial Flood Watch, which provides consistent and timely technical information about the potential for flooding
  • 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

Local flood messages

There are 3 types of local flood messages:

  • flood warning: flooding is imminent or already occurring
  • flood watch: there is the potential for flooding
  • watershed conditions statements: flood Outlook (an early notice of the potential for flooding based on heavy rain, snow melt etc.) and water safety information.

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.
