Flows on the Grand River and its tributaries can vary dramatically from season to season or even from one day to the next. It is important to be aware of changes in flows before setting out on your trip.
The spring melt or the release of water from GRCA reservoirs can result in higher flows for several days. A major rainstorm - even one many miles away - can result in sudden increases in water levels that last for several days.
You can check the flows in the Grand River:
The GRCA owns 29 dams and there are over 100 other dams within the watershed. While all GRCA dams are marked between May and October, some that are privately owned are not marked and may not be easy to see.

You are responsible for your own safety when paddling the Grand River system. Although you don't need a licence for most canoes and kayaks, you must have safety equipment on board. For more information on safe boating, and to learn about federal safety regulations for paddlers, go to the Transport Canada website and read the Safe Boating Guide.
