How to fish it · for Rainbow
When
Conditions are not ideal but fishable at Tan-y-Mynydd Trout Fishery. The ripple should help fish move and feed more confidently. Very warm conditions — trout have a narrower safe zone of cool, oxygen-rich water. Fish only at first light or last light, use barbless hooks, keep fish in the water during release, and stop if fish struggle to recover.
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

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.

Bank

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

About this water

A North Wales commercial fishery at Moelfre near Abergele, operating multiple pools with an unusually broad species list — rainbow, brown, blue, and tiger trout, with a fishery record rainbow at 21lb and brown trout to 10lb plus. A Troutmasters venue, barbless-only throughout. The fishery produces its own Skinny Buzzer range, which is a useful clue about what works: precise, slender midge imitations fished on fine tippet consistently outperform attractor flies here.
