Description
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.
