How to fish it · for Trout
When
April–June; late evenings July–September
Where
Start with Diawl Bach (12-14) — 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 Diawl Bach (12-14) — on the bob / top dropper. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

Fish early and late, try deeper during the heat of the day with a fast-sinking line.

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

Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.
