How to fish it · for Rainbow
When
Conditions are not ideal but fishable at Duncton Mill Trout Fishery.
Where
Start with Floating Fry (8-10) on a Fish as a single fly. 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 Floating Fry (8-10) on a Fish as a single fly. 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

A fry-imitating pattern stripped through the margins can save a blank in autumn.

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.

About this water

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.
