Start with Diawl Bach (12-14) — on the bob / top dropper — slow figure-of-eight retrieve. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
Fish early and late, try deeper during the heat of the day with a fast-sinking line.
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

Numbers are intensity 0 (none) to 3 (peak) — a guide, not a guarantee.
A reasonable day here, though cloud isn't quite in the sweet spot.
A polished South Downs fly fishery near Petworth built around four gin-clear lakes and a notably varied stocked-trout offer. Duncton Mill is open all year and stocks fish direct from its own farm, with official material confirming rainbow trout, brown trout, tiger trout, and sparctic char. It is a tightly managed fishery with online purchasing, quota-style access for non-members, and a deliberately controlled catch-and-take format rather than a casual mixed-rule stillwater.
