How to fish it · for atlantic salmon
When
Morning into early afternoon.
Where
Pool tails, steadier runs, and any water with pace.
Method
Fish a sensible line-and-fly combination for the height and pace of water.
Kit
13 ft #8/9 double-hander in spate, 10 ft #8 single in low water. Floating line plus a fast-sink tip. 12–15 lb fluoro tippet.
Why this works
⚠️ Water at 18.7°C — above the atlantic salmon caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots. Poor conditions based on river hydrology.

About this water

Major limestone river with wild brown trout and a run of salmon and sea trout in the lower reaches. Carlow area offers good trout fishing with solid mayfly and olive hatches. The Barrow is one of Ireland's longest rivers and rewards patient exploration. Clear limestone water allows sight-fishing. Upper reaches hold quality browns; lower river more suited to dace and roach. For 2026 this is a catch-and-release fishery under the Wild Salmon & Sea Trout Tagging Scheme — all salmon and grilse must be returned.
