Grand River Ontario Hatch Chart

The Grand River in southern Ontario is often boasted as being one of the best brown trout fly fishing rivers in Ontario. Many of us would beg to differ on that point, but it remains a very popular destination for fly fishers. The flow of the Grand River is regulated by the Shand Dam. There is an abundance of insect life that flows through this bottom draw dam year round, so the trout in the river are well fed.
