Carsfad Dam, Galloway Hydroelectric Power Scheme

Carsfad Dam is part of the Galloway Hydroelectric Power Scheme, designed by James Williamson with consulting engineers Sir Alexander Gibb and Merz and McLellan in 1936. It features a long, curved concrete arch and gravity dam, with a single control tower located at the center and an elevated roadway along the crest supported by piers over a fixed spillway. The roadway has a concrete parapet, and larger piers flanking the control tower act as buttresses on the downstream face. The control tower spans a walkway and has chamfered upper corners, with a tall, narrow, round-headed opening at the base and a single rounded-headed window above. The doorway has a metal covering added in 2009. At the base of the dam, on the south side, there is a valve-house made of reinforced concrete situated directly beneath the control tower.
