The Clady River (Irish: An Chláidigh, meaning 'the One Who Washes' or 'the Strong-Flowing One'[1]) is a small river in Gweedore (Irish: Gaoth Dobhair), a district in the north-west of County Donegal in Ulster, the northern province in Ireland.

[1][2][3][4] The river flows entirely within the Civil Parish of Tullaghobegly (Irish: Tulacha Beigile).

[5] The Clady River flows out of the western end of Lower Lough Nacung (Irish: Loch na Cuinge Íochtarach) in Gweedore.

[9][10][11] The power station, officially called Clady Power Station, is located in the townland of Dore, and is just under two miles south-west of where the Clady River leaves Lower Lough Nacung.

A 'canal' was built to carry the diverted water from the river, as it flowed out of Lower Lough Nacung, to the power station.
