Scope and Content Mullardoch-Fasnakyle-Affric Project, contract no 10, Fasnakyle Tunnel, surge shaft lining completed, 4 September 1950 Hydro-electric power stations work by using the power of flowing water to turn turbines which rotate generators to produce electricity. Water controlled by a dam on Loch Mullardoch passes through a small generating station, before being directed along a 5km long tunnel to Loch Benevean (Beinn a'Mheadhoin). From there it passes along another 5km long tunnel to Fasnakyle power station. The surge shaft for the tunnel linking Loch Benevean shown with Fasnakyle Power Station. If the power station is shut down, the water moving down the tunnel rises up this shaft, to avoid damage to the station equipment. The shaft has been excavated through rock, and lined with reinforced concrete. The Mullardoch-Fasnakyle-Affric Project was the first part of the Affric/ Beauly scheme to be built. Great care was taken in its design and construction to minimise the impact on the fine scenery in the area. The Affric/ Beauly scheme is one of eight large schemes built by the Board from the 1940s to the 1960s. Source: RCAHMS contribution to SCRAN.
