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.
A 2017 Inland Fisheries Ireland stock survey found invertebrates in the majority of Lough Beagh's brown trout stomachs that contained food, sampled in July/August, confirming aquatic prey is a real part of the diet even though the taxa aren't identified. Otherwise the food character here is modelled, not observed: general lough guidance suggests chironomids present from spring into autumn, small olives building through late spring, and sedges and terrestrial falls on warm summer evenings — general expectations for this lough type, not confirmed local hatches.
Lough Beagh is part of the Lackagh system in Glenveagh National Park — NOT the Eske system. Sea-trout identity inherited from the Lackagh/Lough Beagh headline system (Phase 2, tier_2). The lough has a notably late season (15 July–30 September) and is a specialist migratory-lough venue.
