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. Welfare note: Water at 20°C — above the pike caution line (19°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots.
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. Welfare note: Water at 20°C — above the pike caution line (19°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots.

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

The Thousand Islands are Ontario's warmwater fly gem — clear granite shorelines and weedbeds along eastern Lake Ontario and the St. Lawrence, full of hard-fighting smallmouth bass, with northern pike, carp and the odd musky. Crayfish and baitfish streamers and poppers for the smallmouth, big flies for the pike, and genuine sight-fishing to carp on the shallows.

Under the surface

The Thousand Islands and eastern Lake Ontario / upper St. Lawrence are superb warmwater fly water — clear granite Frontenac-Arch shorelines, weedbeds and current edges holding hard-fighting smallmouth bass, northern pike and carp, with musky as an edge-case prize. Streamer, popper, crayfish and baitfish country.
