Lednock Dam is a diamond headed buttress dam (one of only two of this type in Scotland) designed specifically to cope with earthquake hazards from the adjacent Highland Boundary Fault. The dam creates a storage reservoir for St. Fillans power station (see separate item). The dam has a fixed spillway and small dispersal valve to the base. The tunnel intake gatehouse for the tunnel through to St. fillans power station is located approximately 750 meters upstream of the dam. Lednok dam is one of only two diamond headed buttress dams in Scotland, the other being at Errochty (see separate item). The dam is an interesting application of this technology and was designed with great attention to its structural integrity because of the threat of earthquakes from the nearby Highland Boundary Fault.
