Royal Botanical Garden’s Fishway

This large structure is probably one of the most well-known sites along the Harbour – the Fishway. Located at the mouth of the Desjardins Canal—the only channel that connects Cootes Paradise and Hamilton Harbour—the Fishway is the Great Lakes’ first two-way fishway and carp barrier.

The Fishway began operating in 1997. It is designed to keep non-native carp out of Cootes while maintaining the flow of water and populations of native aquatic species. Before the installation of the Fishway there were an estimated 70,000 carp in the marsh, now it is estimated there are less than 1,000! For more information click here.
