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. (Uses the northern streamer pack as a stand-in; a dedicated warmwater/bass pack is the right follow-up.)
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
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. (Uses the northern streamer pack as a stand-in; a dedicated warmwater/bass pack is the right follow-up.)
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.
