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.

Munroe Killer
Munroe Killer
10–14 doubles · Salmon fly
Traditional Irish salmon fly with long local history. Popular on the Munster rivers; the black/yellow combination has worked reliably for grilse fishing throughout the summer.

About this water

Old Red Sandstone geology gives the water a peaty, amber character that clears quickly after rain. Sea trout and grilse run from June on high water. Not a large river by Irish standards, but genuine migratory fish use it, and the brown trout in the upper reaches are wild and willing on the dry fly through spring. Local club access. The Bantry Bay setting — mountains, sea inlets, southwest light — makes this worth visiting even on a quiet day. For 2026 this is a catch-and-release fishery under the Wild Salmon & Sea Trout Tagging Scheme — all salmon and grilse must be returned.

Hatches & food

EPA freshwater monitoring on the River Coomhola confirms mayflies, stoneflies, caddis, aquatic diptera and freshwater shrimp are present in the riverbed community. The records establish food presence rather than emergence timing or a dependable rise.
