How to fish it · for Trout
When
June–September
Where
Set up a broadside drift and cover the water systematically. Work Caddis Emerger on the bob and Diawl Bach on the point.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work Caddis Emerger 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. Move along the bank and try a different angle or depth before changing fly.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Bank

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