Atlantic Salmon fly box

Connemara/Mayo low water: a lightly-dressed shrimp on a floating line with sink tip, sized down from 8s in cold spring water to 12s and 14s as summer water warms and clears. Where the current runs faster, a slim tube or hairwing swung through tracks better than a shrimp.

About this water

Fast-draining basalt catchment — rises and drops quickly after rain. Salmon from May with grilse from June. Fly only on much of the water. Brown trout are plentiful. An intimate river that fishes well for a single angler. Day permits available. Volcanic bedrock underlies this river. Atlantic salmon are managed under DAERA and Loughs Agency conservation byelaws, with mandatory catch-and-release on many waters; check current rules before fishing.

Hatches & food

No venue-specific hatch data yet; as an upland spate/headwater stream, expect brief, rain-driven stonefly and terrestrial activity rather than a dependable hatch — treat this as general guidance only.
