Short, steep spate river in southwest Donegal, rising in the Bluestack Mountains and flowing south past Frosses and Inver into Inver Bay on Donegal Bay. Ultra-rapid response to rainfall — often fishable within two hours of a rise and dropped out again within a day. Peaty uplands give it a permanent amber tinge. Historically important for Atlantic salmon research and stocking studies; holds a concentrated spring run plus a strong grilse and sea trout run in summer. Not to be confused with the Lennon/Lackagh systems in north Donegal. For 2026 this is a catch-and-release fishery under the Wild Salmon & Sea Trout Tagging Scheme — all salmon and grilse must be returned.
