Decent — worth a look
Low and clear — careful approach country. Low water tactics — small singles, riffling hitch in the smooth glides.

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

Brown trout, sea trout, and salmon lough in Connemara. Fishery-managed; bank and boat access available. Rules vary by water condition. 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.

Under the surface

Lough Muck is the lower of the two loughs of the Culfin fishery in north Connemara, six miles west of Leenane, taking the outflow of Lough Fee above it and passing its own water down the short Culfin River to the sea. It sits in the same hard granite-and-quartzite country beneath the Twelve Bens, the water clear, soft and acidic off mountain and blanket bog, the Leenane road running close along its shore. Muck offers salmon, sea trout and a good stock of small wild brown trout, the migratory fish running up the Culfin off the tide on the summer water. The character is a small, exposed, mountain-fringed Connemara lough — rocky shoals, a stony shore and peat-stained bays open to the wind. This is boat-and-bank fishing read by the wave and the shoreline lies; the connecting river wades steadily on firm granite rock and gravel.
