One of very few stillwaters in the British Isles where spring salmon are regularly taken by fly from a drifting boat. Carrowmore Lake sits in the Bangor Erris district of north Mayo — 2,300 acres of peaty lough system raised slightly by a small dam in the 1980s, ringed by bog and supplied by the Glencullin and Oweninny systems. Spring fish average 7lb and double-figure fish are a regular occurrence; sea trout from mid-June. The productive drifts concentrate on Bog Bay, Paradise Bay, and the mouth of the Glencullin river. Fish it like a lough, not a river — a team of wets worked slowly across a broadside drift, with a Green Peter or large Dabbler on the bob in any kind of breeze. 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.
No venue-specific hatch data yet; as a Mayo/Sligo Atlantic oligotrophic upland lough, expect the general stillwater food base of buzzers, olives and sedges typical of this water type — treat this as a general expectation, not an observed hatch.
