Great Slave Lake is North America's deepest, a vast Shield lake whose East Arm is a celebrated trophy lake-trout fishery. After ice-off the big lakers hunt the cold shallows where they're catchable on stripped streamers, and the feeder rivers run with Arctic grayling. Northern pike add another fly target. Immense, cold and wild, mostly fished from fly-in lodges.
Summer pike — dawn and dusk topwater
Good wave on — drift country. A useful wave. Work the productive shore.
Pike are ambush-feeding from weed cover. Fry and small perch concentrate in the warm shallows, drawing pike in during low-light periods. Mid-day pike retreat to deeper weed channels.

How to fish it · for pike
When
Pike are ambush-feeding from weed cover. Fry and small perch concentrate in the warm shallows, drawing pike in during low-light periods. Mid-day pike retreat to deeper weed channels.
Where
Summer pike on the fly. Fish early (first light) and late (last hour) when pike push shallow to feed. Topwater is king — poppers and gurglers over weed beds. Mid-day fish hold deep in weed channels. Take a break during the heat of the day. Use a 9-10wt rod with a stiff butt for turning big fish away from weed.

The plan
Plan A
Summer pike on the fly. Fish early (first light) and late (last hour) when pike push shallow to feed. Topwater is king — poppers and gurglers over weed beds. Mid-day fish hold deep in weed channels. Take a break during the heat of the day. Use a 9-10wt rod with a stiff butt for turning big fish away from weed.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water

Under the surface
Great Slave Lake is the deepest lake in North America, a huge Shield water holding trophy lake trout, Arctic grayling and northern pike, with the famous East Arm a renowned trophy lake-trout fishery served by fly-in lodges. Cold, clear and immense, it offers shallow-water fly fishing for big lakers after ice-off and grayling in the rivers that feed it.
