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

The short river draining Lough Beltra to the sea at Newport, Co. Mayo — part of the wider Burrishoole system that has been the centre of Marine Institute Atlantic salmon research (the Furnace laboratory) for close to forty years. Flow is buffered somewhat by Lough Beltra above, giving a steadier character than a typical short coastal spate river. Salmon and sea trout run through the summer, with the best of the fishing from July into August. Brown trout are present throughout.
