How to fish it · for Trout
When
The lake olive is on. Sedge may also come into play as the day warms. Calm conditions may limit drift fishing — consider buzzers or dry fly if fish are rising.
Where
With limited drift, anchor or fish static from sheltered positions. Work Bibio Hopper on the bob, CDC Dry on the middle dropper, and Olive Damsel on the point. In the calm, a single dry fly or buzzer-under-bung approach may be more effective than a drifted team.
The plan
Plan A

With limited drift, anchor or fish static from sheltered positions. Work Bibio Hopper on the bob, CDC Dry on the middle dropper, and Olive Damsel on the point. In the calm, a single dry fly or buzzer-under-bung approach may be more effective than a drifted team.

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.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
