The vast waters of Lough Mask, in County Mayo, contain some of Ireland's largest brown trout. These waters, although noted internationally as game fisheries, provide some pike and perch fishing for the coarse angler.
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 around mid-April, and it continues to produce more trout with every season.
Open season runs from 15 February until 30 September.
