The MNR provides flood forecast messages to conservation authorities and municipalities to enable them to prepare for, track and manage local flooding. Flood forecast messages are not flood warnings.
Your local conservation authority (CA) or municipality issues flood warnings. For more information on your local situation, check with your conservation authority or municipality. If you live in a community that is not serviced by a conservation authority, any flood advisories or flood warnings in your area are issued by the nearest MNR district office. Who to Contact

FLOOD SAFETY AND WATERSHED CONDITIONS BULLETIN: unsafe lake, river and channel conditions exist.
Protecting lives, property and resources from floods and other natural hazards is an important part of MNR’s work. To do that, we must be able to forecast when there is a risk of flooding and help limit the impact if a flood does happen. More than 4,000 sensors feed information from approximately 1,200 stations across the province.
The Surface Water Monitoring Centre in Peterborough uses high-tech equipment to monitor water levels on lakes, rivers and streams in Ontario.
Experts at the centre routinely review:
This provides reliable and timely information about the potential for flooding to occur.
