About this water

A small Donegal spate river at Carrick, in the shadow of Slieve League, with its companion the Yellow River — the Owenwee — open for 2026. It fishes on a flood: spring salmon early, then grilse and sea trout through the summer when the water rises and fresh fish run. For 2026 it is catch-and-release. Carry the Salmon and Sea Trout State Licence; the water is IFI and local club controlled.
