How to fish it · for brown trout
When
The buzzer is on. Sedge may also come into play as the day warms. Dusk on the lake is prime time for surface feeding — stay out as long as light allows.
Where
Work Pheasant Tail Nymph on the bob and Diawl Bach on the point.

The plan
Plan A
Work Pheasant Tail Nymph on the bob and Diawl Bach 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.
