Loch Doon Dam provides the main seasonal storage for the upper three power stations on the Dee. Its original level was raised 27 ft by the construction of the dam across its natural outlet at the northern end.
The total length of the dam is 980 ft, the main central portion consisting of a mass concrete structure of the
gravity type, slightly curved in plan. There is a 16 ft wide roadway along the crest. Flood water is dealt with by the 110 ft wide spillway assisted by a group of three siphons on the north flank. An interesting feature of the dam is the fish pass, which rises spirally inside a circular concrete tower within the reservoir.
This dam was also completed in 1937. The consulting engineer was Sir Alexander Gibb & Partners and the
main contractor, Sir Robert McAlpine & Sons Ltd.
