About this water

The Coppermine is a great Arctic wilderness river running north to Coronation Gulf — Arctic grayling and lake trout through its tundra reaches and sea-run char near the coast. It's classic expedition water of riffle, pool and rapid, fished on remote canoe trips and fly-in excursions, with superb grayling fishing and the chance of char near the salt. Barrenland fly fishing at its wildest.

A classic northern wilderness river — long stretches of riffle, pool and rapid — it offers superb grayling fishing and char near the coast, fished on remote canoe expeditions and fly-in trips.
