A flashy granite spate river in Gaoth Dobhair (Gweedore), West Donegal, that runs to the Atlantic via Bloody Foreland. Clady responds rapidly to rainfall (2–3 hours) and fishes best as a river rises and clears. Spring salmon from February; grilse and sea trout from June. The river runs through wild Donegal moorland and has a reputation for good-quality sea-trout fishing. Multiple named pools; public access available to most sections. (Not to be confused with the Co. Londonderry Clady, a tributary of the Lower Bann.) For 2026 this is a catch-and-release fishery under the Wild Salmon & Sea Trout Tagging Scheme — all salmon and grilse must be returned.
EPA river-invertebrate monitoring on the Clady (Gweedore) confirms a broad food base is present — mayflies, stoneflies, caddis, chironomids and blackfly larvae, plus freshwater shrimp and hoglice (Gammarus, Asellus) — but this is kick-sample presence evidence only, not a record of hatch timing or a dependable rise.
