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
Good conditions. Temperature is favourable (100), Feeding time is weakest (10).

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.

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.
