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
Fair conditions based on river hydrology and migration patterns.

About this water

Still probably the strongest brand-name Connemara sea-trout proposition you can talk about without overselling. Sea trout start running in June, peak in July, and continue on floods through the rest of the season. Ballynahinch Castle still says Lower Ballynahinch Lake can produce sea trout in midsummer — but that confidence sits within a diminished modern baseline, not a return to historical abundance. Best approached as a modest-numbers, flood- and timing-dependent fishery rather than a restored glory-days one. The river-lake combination and the prestige of the fishery still matter; the stock story does not justify old-school hype. Grilse are the main salmon target, moving quickly through the system after rain. In Galway, Connemara and Ballinakill districts it is an offence to kill sea trout over 40 cm. Lough Inagh itself holds wild brown trout. The castle hotel fishery is among Ireland's most renowned. For 2026 this is a catch-and-release fishery under the Wild Salmon & Sea Trout Tagging Scheme — all salmon and grilse must be returned.
