How to fish it · for rainbow trout
When
Conditions are not ideal but fishable at Stithians Reservoir.
Where
Start with Diawl Bach (12-14) — on the bob / top dropper — slow figure-of-eight retrieve. Rainbows respond to more active retrieves — try short strips between pauses. 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 — slow figure-of-eight retrieve. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
Plan B
If the main plan stalls, drop to a size 14–16 midge — switch to a washing-line or suspender rig and change drift line before you change food group.
Watch for
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Bank, sheltered shores
In wind, bank fish the lee shore — boats can anchor in productive areas if conditions allow.
