Clunie Dam, Tummel Garry Hydro Electric Scheme

Clunie Dam, part of the Tummel Garry Hydro Electric Scheme, was constructed in 1950 by engineer James Williamson for the North of Scotland Hydro Electric Board and main contractors George Wimpey and Son Ltd. This large concrete gravity dam features prominent drum gates and an oversailing walkway, with a fish pass located to the east. The dam is made of pre-cast concrete and includes metal drum gates. It has a large central buttress and smaller buttresses flanking the spillways, which are integrated with wave walls at the base of the dam. The deck access walkway is supported by wide depressed segmental arches that span the automatic drum gates, with battered fixed spillways underneath. To the east, there is a cascade of linked concrete pools that form a fish ladder.

The intake gatehouse towers include a large central tower next to the upstream face of the dam, with an attached lower block to the north and two smaller rectangular towers on the outer wings of the dam. All structures are made of reinforced concrete and feature a moulded eaves course and a slightly recessed deep parapet above. The towers have regular fenestration with plain surrounds and large vehicular access doors on the north elevations, all fitted with boarded teak doors. Additionally, there are smaller control towers to the southeast of the upstream face, designed similarly, which control the tunnel intake to the power station.
