Lough Eske — 'lake of the fish' — lies just north-east of Donegal Town, a nine-hundred-acre lough cradled on three sides by the Bluestack Mountains and connected to the sea by the short River Eske. It is deep, plunging to a hundred feet, and ringed by wooded shore and old forest. The water is soft and lightly peat-tinged off the granite-and-schist Bluestacks, the catchment a mix of mountain and bog. Eske is noted for its spring salmon — fish to twenty pounds and more present from Easter to season's end — with sea trout from July, Arctic char in the depths and a productive head of brown trout. The character is a deep, scenic mountain lough fished from the boat over rocky shoals and along the shore lies, the salmon read by the drift and the inflow mouths. Wading has little part here; this is boat water on an unspoiled highland lake.

Wading: Deep mountain lough, boat water

No venue-specific hatch data yet; as a mixed stillwater, expect a modest midge, olive and sedge food base typical of Donegal's oligotrophic loughs — a general expectation for this water type, not an observed hatch.
