How to fish it · for Atlantic Salmon
When
Summer through autumn. Fish the drop after rain; the lower pools take fresh fish on combined tide-and-river timing.
Where
Lower Ogmore pools above the estuary at Ogmore-by-Sea; named lies through the Ogmore AA water.
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
Excellent — water temperature is right today, though river flow could be better.
Likely species
Stoneflies
Gammarids
