The Loch Monar is a dam at the end of Glen Strathfarrar in the Western Highlands of Scotland , about 50 kilometers west of Inverness . The water has been used by the Affric-Beauly power plants since 1962 .
The lake is dammed by two structures, the Loch Monar Dam and the Loichel Dam . The main dam is the Loch Monar Dam, one of the arch dams rarely used in Great Britain . It is 39 m high and 161 m long. The Loichel Dam is a smaller gravity dam that prevents the dammed Loch Monar from flowing away via a saddle in the side valley.
In addition to the natural tributaries, the reservoir is also supplied with water from the Uisge Misgeach valley. The water is collected on both sides of the valley with supply tunnels. The water from the right side of the valley facing away from the lake is led to the left side via a culvert. At the lowest point of the culvert is the Misgeach doping power plant, which turbines the residual water for the Farrar River. If there is a lack of water in the supply lines and Loch Monar is full, the supply tunnel to the lake can also be operated in the opposite direction and water from the reservoir can be introduced for doping .
The water from Loch Monar is fed through a nine-kilometer long inlet tunnel to the Deanie cavern center, where it is processed by two vertical Francis turbines . Each generator delivers an output of 19 MW, so that the entire system has an output of 38 MW. 94 GWh are produced annually.
