How to fish it · for Atlantic Salmon
When
Spring from March; grilse build through June and July. The Ballynahinch / Lough Inagh system fishes both river and lough drifts. Spate-responsive on the river, settled-wind for the lough.
Where
Ballynahinch Castle beats and the loughs upstream — Inagh and Derryclare. Named pools on the river; drift lines along the shore margins on the loughs.
Method
Small doubles 10 to 12 across-and-down on a floating line; small tubes on a sink-tip in spring water. Catch-and-release encouraged across most Irish salmon water.
Kit
10 ft #7 single-hander on the smaller spate rivers; 11 ft switch where the river opens out. Floating line plus light sink-tip. 10 to 12 lb fluoro tippet.
Why this works
The river is in textbook shape. River dropping nicely into shape after a lift — textbook conditions. Clearing nicely — classic taking conditions. 13.6°C — in the ideal taking range for autumn salmon. This is the window experienced salmon anglers wait for — if you can get to the river, go now.
