Ranked for today
Atlantic Salmon fly box

Munster Blackwater and neighbouring SW spring rivers: when the water is cold or running high, a tube fly fished deep on a Skagit head or sinking shooting head with a heavier leader finds fish that a floating line can't reach. Comes down to a 9'-10' single-handed rod and small flies on an 8lb tippet once the river drops into summer trim.

About this water

Cloonlaghlin is an upper lough in the Waterville system — quiet water above the main fishery, where sea trout and salmon rest after running up through Currane. Boat only; bank fishing is not an option here. Access is through the Waterville/Currane arrangements — confirm locally before travelling, as the management situation is currently in flux. The fish here are not the target of the serious Currane angler, which means they are occasionally less wary than they should be. For 2026 this remains an open fishery — salmon may be retained in season under the Wild Salmon & Sea Trout Tagging Scheme and bag limits, with catch-and-release at other times.

Hatches & food

No venue-specific hatch data yet; as an oligotrophic upland lough in this Cork/Kerry sandstone-freestone system, expect the typical acid-water stillwater character of thin buzzer and sedge hatches with terrestrial and shrimp interest close to the bank — treat this as a general expectation, not an observed hatch.
