About this water

The Grand below Shand Dam is one of Canada's finest brown-trout tailwaters — cool, rich, limestone bottom-release water through Fergus and Elora that grows good browns and serves up prolific hatches. There's a fly/artificial special-regulation reach, genuine year-round trout fishing, and lovely dry-fly water in a pretty valley. A tailwater gem hiding in southern Ontario.

Under the surface

Below Shand Dam at Belwood, the Grand is one of eastern Canada's best brown-trout tailwaters — cool, limestone-rich bottom-release water through the Fergus–Elora corridor that grows wild and stocked brown trout with prolific hatches. Tailwater stability and rich water make for a genuine year-round trout fishery, with a special regulation (fly/artificial) reach and good dry-fly fishing in a pretty Ontario river valley.
