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 22.9°C. This is the line where catch-and-release kills atlantic salmon. Do not fish for them today.

About this water

A Kerry spate river draining the foothills of the Sliabh Mish into Castlemaine Harbour. It is open for 2026, and it fishes as spate rivers do — grilse and sea trout running from June on a rise of water, holding briefly in the pools before moving on. Castlemaine and Killarney district permits; the Salmon and Sea Trout State Licence is required.
