Laggan Dam was the first large siphon spillway used in the UK. [6] The foundations are built on granite, and the dam was built in seven sections, with copper strip and hot poured asphalt water stops in the joints. [4] Water from the dam is conveyed to Loch Treig through three miles (5 kilometres) of tunnel.
Laggan Dam was constructed at a constriction in the valley approximately 4.5 miles (7 km) downstream of Loch Laggan creating Laggan Reservoir. This is linked to Loch Laggan by a short section of the River Spean, which was dredged to make use of the storage capacity in the loch. While the downstream dam site required a larger dam than an ...

Regardless of path that it takes, most of the water arrives at Loch Tummel, where it is impounded by the Clunie Dam located in a narrow valley at the eastern end of the loch. The construction of this dam raised the water level by 17 feet (5.2 m) [ 49 ] to create a reservoir with a capacity of 36,400,000 cubic metres. [ 50 ]
