How to fish it · for Trout
When
April–September
Where
Start with Bibio (10-12) — on the bob / top dropper. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Bibio (10-12) — on the bob / top dropper. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

If surface work dries up, try a diawl bach or hare's ear on the point and skate a sedge pattern on the bob at last light.

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.
