About this water

The Mabou flows through Inverness County to the Gulf of St. Lawrence — Cape Breton river country, with a salmon-fishing tradition that runs as deep as the Gaelic heritage. Spate-driven: fast to colour after rain, fast to clear, with fish that run on any decent lift and rest briefly in the pools before pushing on. Summer grilse dominate July and August; multi-sea-winter fish are present in early season. Local knowledge matters on the Mabou more than most rivers. The pools have names, and the names have history behind them. Atlantic salmon are managed under DFO conservation rules — mandatory catch-and-release of large (multi-sea-winter) salmon applies in most areas, with any grilse retention strictly limited by zone; check current regulations before fishing.
