River flows in the Grand River watershed south of Caledonia are expected to continue rising Monday and peak overnight Monday into Tuesday morning.

The Grand River Conservation Authority issued a flood warning for the entire watershed this weekend following a period of record-setting rainfall.

The areas of Cayuga and Dunnville can still expect to see more rising water Monday night. River flows are expected to be "extremely high" through the southern watershed for the rest of the week, the GRCA said.

Flows near Cayuga and Dunville are expected to exceed those experienced during the June 2017 flood.

In the northern and central portions of the Grand River watershed, river flows have already peaked and are now continuing to recede. River flows will remain high throughout the week as water runoff from reservoirs moves through the system, the GRCA said.

Debris such as trees and branches was swept into the river during the weekend storm and continues to pose a risk on waterways.

People are asked to stay away from all waterways due to "extreme risk," the GRCA said.

The GRCA is expected to make another update on Wednesday.
