On March 9, 2026, the Grand River Conservation Authority issued new flood warnings for Grand Valley and St. Jacobs as water levels continue to rise. This update affects several communities near Guelph, Ontario, where high water and potential flooding remain a major concern for local residents.
A flood warning means that flooding is already happening or is expected to happen soon in specific areas. These warnings are currently active for Grand Valley, St. Jacobs, New Hamburg, Ayr, West Montrose, Drayton, Paris, Brantford, and Haldimand County. For the rest of the watershed, a flood watch is still in effect, which means that flooding is possible but not certain.
The conservation authority is using its system of seven large reservoirs to help manage water levels and reduce the risk of flooding during the spring runoff. Residents are being asked to stay away from all local waterways, as fast-flowing water and slippery banks can create dangerous conditions for people and pets.
Municipal emergency services, including local police and fire departments, are working to manage any impacts on the community. Residents in the affected areas should stay alert and follow safety guidance from local officials as the situation develops throughout the week.
