Getting there

A genuinely species-diverse river - 94 fish species have been recorded along its length, out of 165 recorded province-wide. Real local knowledge worth passing on: despite persistent folklore about salmon and steelhead runs, both are rare to essentially absent this far up the system (long-time local anglers report catching only a couple of steelhead over decades) - most large fish spotted from bridges and mistaken for salmon turn out to be common carp. The real fishery here is smallmouth bass, plus channel catfish (a genuine local highlight around Harris Park) and occasional surprises like bigmouth buffalo, gar, or muskie. The lower river near Chatham and Lake St. Clair is a different, walleye-and-perch-focused fishery in its own right.
