How to fish it · for atlantic salmon
When
Mainly autumn, in very small numbers. The Afan is not a salmon destination — a fresh fish here is a notable event.
Where
Lower river pools above the tidal limit at Port Talbot.
Method
Small doubles 10 to 12 across-and-down on a floating line; small tubes on a sink-tip in spring or coloured water. Fish the named lies in each pool, working systematically before moving on. Mandatory catch-and-release under NRW byelaw — every salmon goes back.
Kit
10 ft #7/8 single-hander or 11 ft switch — small spate scale; double-handers are wasted on these rivers. Floating line plus light sink-tip. 10 to 12 lb fluoro tippet.
Why this works
Very poor — barometric pressure is working for you, but water clarity is the limiting factor today.

About this water

Small spate river down the Afan Valley to the Severn at Port Talbot — a recovery story as much as a fishery. A century of coal and industry left the river largely barren; reclamation work has brought brown trout, sewin, and the beginnings of a salmon run back to water that was effectively dead within living memory. Condition-driven fishing — falling water, colour, temperature — and a conservation-sensitive context. Treat it as a place to fish carefully rather than to fill the bag. Atlantic salmon are under serious conservation pressure — Natural Resources Wales mandates catch-and-release for salmon on all rivers, so all fish must be returned.

Sea trout: Variable seasonal (2026) — Recovering industrial valley river. Sewin run modest but consistent enough through summer to warrant a sea-trout designation. All-Wales At Risk picture applies; treat as a low-density conservation fishery.
