Kendoon Loch (Reservoir) has been formed by damming the Water of Ken. It supplies water to Kendoon Power Station (NX68NW 105.00), and is a major component of Stage II of the Galloway Hydro-Electric Scheme. The North Dam (NX69SW 90.00) and the South Dam (NX68NW 107.00) control the supply of water to the Water of Deugh and Water of Ken respectively.
This structure has also been known as Deugh Dam.

Publication Account (2007)
Less than a mile west of Ken Dam is Deuch Dam. Its arched section has a maximum height of 85 ft from the river bed to the crest footway and has a developed length of 356 ft, a radius of 220 ft and a 3 to 1 batter. The total length, including the gravity section containing the spillway, is 780 ft. This dam was also completed in 1937 with the same engineer and contractor as Ken Dam.

Field Visit (2010)
This dam regulates the outflow of the Water of Deugh from Kendoon Loch to regulate water level and maintain sufficient storage. This is part of a three dam system for this loch with the Kendoon Dam controlling outflow into an aqueduct leading to the Blackwater dam where water enters a buried pipeway with surge tower and thence into the powerhouse at Kendoon. This dam is a significant part of the infrastructure of phase II of the Galloway Power Scheme. The dam is of the hybrid arch and gravity type which characterises the Galloway scheme. It has a prominent setting, making a good contribution to the landscape. Architectural design interest is exhibited in the walkway oversailing the spillway on large piers and the functionalist modern classical scheme as part of a cohesive design with the powerhouse. The curved spillway running at 90 degrees perpendicular to the base of the dam and incorporating naturally outcropping rocks is also a relatively unusual feature.
