How to fish it · for Trout
When
The daddy longlegs are on. Wind-blown Terrestrials may also come into play as the day warms. Calm evenings on lakes can be magical — watch for rises and fish individual fish with dries. Dusk on the lake is prime time for surface feeding — stay out as long as light allows.
Where
With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. Calm evenings are perfect for individual dry fly work — target rising fish. Keep a sedge-style dry or emerger on a short leader for the evening rise.
The plan
Plan A

With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. Calm evenings are perfect for individual dry fly work — target rising fish. Keep a sedge-style dry or emerger on a short leader for the evening rise.

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.

Either bank or boat

Calm evenings can fish well from bank or boat — target rising fish wherever you find them.
