This dam is located 13 km below the natural outlet of the loch, and thus raised its level to provide flow regulation and a degree of storage for Fasnakyle power station (see separate listing). The reservoir is supplemented by water from Mullardoch dam at the top of Glen Strathfarrar (see separate item) which passes though an underground power station before entering Loch Beinn a Mhedoin upstream of Bennevean dam. The water level in the loch is closely controlled to ensure that the level remains virtually constant, ensuring that the scenic amenity of the upper Glen Affric is affected as little as possible.
Sandwood Bay (Scottish Gaelic: BÃ gh Shanabhait) is a natural bay in Sutherland, on the far north-west coast of mainland Scotland. It is best known for its mile-long beach and Am Buachaille, a sea stack, and lies about 5 miles south of Cape Wrath. Behind the bay’s large dunes, stretches Sandwood Loch – a freshwater loch full of brown and sea trout. Though remote, and with no road access, the bay is easily reached by a 4-mile long, yet well-trodden and fairly flat, path leading from the gravel car park at the hamlet of Blairmore. Sandwood Bay is part of the Sandwood Estate which is run by the John Muir Trust. The beach is considered to be one of the cleanest and most unspoilt beaches in the whole of mainland Britain.
