This dam regulates the flow of the River Dee and provides a modest storage reservoir in Tongland Loch. Water from the outflow enters a tunnel and thence a concrete pressure aqueduct which conveys it to the base of the surge tower. This dam is a hybrid type, composed of part arch dam and part gravity section with both fixed spillway and siphon valves. It is a significant complex of different engineering approaches to the construction of a dam, each particularly suited to the profile of the valley at that point. The combination of arch and gravity sections is a common theme in the dams on the Galloway scheme. The dam also exhibits a functionalist classical design scheme, especially evident to the control turret which is cohesive with the design of the powerhouse at Tongland. There has been a limited degree of later alteration including the addition of screens and automatic screen cleaners. PL Payne, 1988, 24; E Wood, 2002, 50; G Hill, 1984.
