Loch Mhor Dam, Foyers Hydroelectric Power Scheme And Former Aluminium Smelter

Loch Mhor Dam, part of the Foyers Hydroelectric Power Scheme and the former Aluminium Smelter, was likely designed by Cameron Burnett for the British Aluminium Company between 1895 and 1896, with later alterations. This large dam consists of two sections, featuring a small crenellated control turret located off-centre to the right (southeast) and a lower, deep rectangular section of the dam wall beyond. The structure is made of concrete, masonry, and rammed earth, with later concrete reinforcement added to the wall on the left (northwest). The dam walls are faced with coursed random rubble, while the turret has shaped coping stones on the left (northwest) and a deep sloped concrete top on the right (southeast). The turret has dressed stone surrounds with flat copes on the parapet, and there is a rammed earth and random rubble wave wall at the outlet. The turret features later uPVC windows.

Inside, the turret has a plain interior with a boarded floor on both the ground and first floors. The original control gear for the sluice gates is set into the walls on the ground floor.
