Full Description

This mass gravity dam of 1956 is 1800 feet in length (548.64 m) and is still in use. <1>

Loch Loyne provides a secondary catchment for the northern section of the Great Glen scheme, feeding water via a tunnel to Cluanie Dam (MHG37170). The dam is of relatively low profile with a fixed spillway and dispersal valve. An internal gallery gives access to the valve-house when the dam is on spill or dispersal valve is open. The valve-house also houses a compensation set with the tailrace providing water to the river. The comp set is deeply recessed to maximise the available head in what is otherwise a relatively shallow dam. The dam is of a relatively small scale and of predominantly standard design. This structure was recorded as part of HES' Hydro-Electric Digitisation Project during 2010-11. <2>
