The Grey Sauble Conservation Authority issued an updated flood watch for the Collingwood, Ontario area on March 9, 2026, as local rivers rise above their normal spring levels. High temperatures and melting snow have combined with recent rainfall to create dangerous conditions near waterways across the region.

The local conservation group reported that many river systems are currently flowing higher than usual for this time of year. These conditions have already led to some roads being closed due to water covering the pavement following a weekend of heavy rain and melting snow.

Forecasts show that another 20 to 40 millimetres of rain is expected to fall starting late Tuesday night and continuing through Wednesday, March 11, 2026. This extra rainfall could lead to more flooding in low-lying areas if the river systems remain high during the week.

Local Collingwood residents have been sharing photos of rising streams and discussing how to prepare for the high water. Officials are warning everyone to stay away from all rivers and streams because the banks may be slippery or unstable.

The fast-moving water and melting ice pose a significant safety risk to the public. The current flood watch is expected to remain in place until March 13, 2026, while officials continue to monitor the impact of the incoming rain.
