About this water

Lough Derriana lies above the main Waterville system, a staging lough for migratory fish moving through the Kerry chain. Boats are available at Clodragh; there is no public bank access. The Waterville/Currane management arrangements are currently unsettled — confirm access locally before you make the drive. For 2026 this remains an open fishery — salmon may be retained in season under the Wild Salmon & Sea Trout Tagging Scheme and bag limits, with catch-and-release at other times.

Under the surface

Lough Derriana is one of the larger upper loughs of the Waterville system in south Kerry, lying among the chain of lakes — Namona, Cloonaghlin, Iskanamacteery — that the Cummeragh and Owengarriff rivers thread down to Lough Currane and the sea. This is remote, beautiful Old Red Sandstone country beneath the high hills of the Iveragh peninsula, the water clear and soft off a catchment of sandstone rock and blanket bog. Derriana is sea-trout water first and foremost, the fish running up into the system off the Currane when the rivers fill and flood, with salmon among them on the high water and wild brown trout through the season. The character is upland lough — rocky shoals, sandstone reefs and peat-stained bays, exposed to the Atlantic wind. This is boat-and-drift fishing read by the wave and the shoreline lies; the connecting streams wade steadily on firm rock.
