How to fish it · for Trout
When
May–October
Where
Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.

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 — at anchor

Windy conditions suit anchoring in productive areas rather than open-water drifting.

Conditions are away from Lac Guéry's sweet spot — it usually fishes best in ripple wind with cloud skies.
