Method
Small doubles 10 to 12 across-and-down on a floating line; small tubes on a sink-tip in spring water. Catch-and-release encouraged across most Irish salmon water.
Kit

Atlantic Salmon fly box

Connemara/Mayo low water: a lightly-dressed shrimp on a floating line with sink tip, sized down from 8s in cold spring water to 12s and 14s as summer water warms and clears. Where the current runs faster, a slim tube or hairwing swung through tracks better than a shrimp.

About this water

Season 1 March to 30 September. Best fish usually taken in spring after the opening. Lough Eske provides holding water and the brief river below concentrates fish during runs. Fish it methodically as sea trout stage before entering. A river of beautiful Donegal setting and consistent sea trout opportunity. Char also present, alongside the salmon, sea trout and brown trout. The Eske system encompasses Lough Eske (the primary holding water) and the short outlet river to Donegal Bay. For 2026 this is a catch-and-release fishery under the Wild Salmon & Sea Trout Tagging Scheme — all salmon and grilse must be returned.

Hatches & food

No venue-specific hatch data yet; as a connected lough-river system, expect the mixed midge, olive and sedge food base typical of Donegal's lough-and-spate waters — a general expectation for this water type, not an observed hatch.

Sea trout: Variable seasonal (2026) — Eske is historically a real Donegal sea-trout system but should not be oversold without fresh per-season catch evidence. Donegal-cluster identity (Eske, Eske Donegal lough) is real and valuable but operates at regional rather than national-flagship scale.
