Lough Mask is a large limestone lough of 22,000 acres in area and, along with Lough Corrib, is one of the best known brown trout fisheries in Ireland. The lough produces good catches to wetfly from about mid-April. Dapping the mayfly, daddylonglegs or grasshopper can bring about excellent results during the various months of the season. The lough continues to produce more trout with every season, last season been one of the better ones even though weather conditions were very unsuitable from July onwards.

Lough Mask is famous for its large ferox trout and every season anglers take a number of these great trout, mostly all over 10 lb and nearly always to trolled baits. The record for the lough is 18 lb, but others over 20 lb have been found including one of 22 lb some 10-years ago and is on display in the IFI office at Cushlough, Ballinrobe, Co. Mayo.
