View On Black Here Loch Laggan Dam, a fantastic piece of architecture set in stunning desolate surroundings. Laggan Dam is a dam located on the River Spean south west of Loch Laggan in the Scottish Highlands. The dam is 700 feet (213 metres) long and rises 170 feet (52 metres) above its foundations, and is part of the Lochaber hydro-electric scheme. The structure was built by Balfour Beatty for the British Aluminium Company and construction was finished in 1934.
Water from the dam is conveyed to Loch Treig through 3 miles (4.8 km) of tunnel. From there, the waters are conveyed to a power house at Fort William via 15 feet (4.6 metre) diameter pipe 15 miles (24 km) long. The dam can be found next to the A86 road from Fort William. *info from Wikipedia
The impressive Laggan Dam, east of Fort William. Only one outflow gate is open. It would make an even more impressive sight with them all open.
