River high but settled. Little in your favour today. Fish the certain lies, or leave it for a better one.

How to fish it · for Atlantic Salmon
When
Summer through autumn. Fish on the drop after rain — the Neath is not a spring salmon river.
Where
Middle and lower Neath pools above the tidal limit. Neath & Dulais AA named beats.
Method
Small doubles 10 to 12 across-and-down on a floating line; small tubes on a sink-tip in spring water. Cover the pools methodically. Mandatory catch-and-release under NRW byelaw — every salmon goes back.
Kit
12 ft #7/8 double-hander or 11 ft switch. Floating line plus light sink-tip. 10 to 12 lb fluoro tippet.
Why this works
Water at 22.1°C. This is the line where catch-and-release kills atlantic salmon. Do not fish for them today.
