About this water

The North Seal is Manitoba's headline fly destination — promoted as one of the top Arctic grayling fisheries in North America, with strong northern pike and lake trout alongside. A clear, rapid-and-pool Shield river deep in the far north, fished fly-in from lodge bases for a genuine grayling/pike/laker grand slam.

Under the surface

Clear far-north Shield river of rapids and pools, a premier Arctic grayling fishery with pike in the slacks and lake trout where it widens.

    Pike carries no closed season in Manitoba's Northeast Division — 'All Other Species' is open year-round per the Manitoba Anglers' Guide. Division assignment for this remote Hudson Bay-lowlands river is a geographic inference (the guide does not name this exact river), not a direct citation.
