How to fish it · for atlantic salmon
When

Method
Fish a sensible line-and-fly combination for the height and pace of water.
Kit
10 ft #7/8 single-hander, floating line, 10–12 lb fluoro leader. Boat seat and waterproofs for the drift.

About this water

Lough Beagh sits in Glenveagh National Park, drained by the Owencarrow / Lackagh river system to Sheephaven Bay. The lough opens for fishing notably late — 15 July through 30 September — making it a specialist late-season migratory venue distinct from the river beats below. Boats with engines available; fly-only. C&R required for salmon and sea trout 40cm+. Part of the Lackagh / Lough Beagh fishery system. For 2026 this is a catch-and-release fishery under the Wild Salmon & Sea Trout Tagging Scheme — all salmon and grilse must be returned.
