Mullardoch Dam & Power Station

A view of Mullardoch dam from a mile or so down Glen Cannich. Note the two sections of spillway on the dam crest, and the gatehouse at the left end of the dam.

Looking at the rear face of the dam, water level drawn down about 35 feet.

Looking back across from the far side of the loch, rear face of the dam on the left, surface works of power station (left) and gatehouse (right) in the centre of the picture, with area of spoil (from the excavation of the power station shaft) on the shore of the loch - the tunnel intakes are under water. I've added some legend to clarify the relative depths of the intakes.

Closeup of the power station surface buildings (left) and tunnel gatehouse (right). The screened opening at the bottom of the stone bank is the overflow pipe from the power station gateshaft.

Inside the gatehouse, looking down the gateshaft on the downstream side. The gate, as in this picture, is normally closed (since the water flows through the power station) - thus the water is a very long way down the shaft (about 100ft from the surface), as it is at the same level as the water in Loch Benevean. Apologies for the poor quality shot.

This diagramatic representation of the Mullardoch-Benevean tunnel will make things clearer - the text is leglible on the full-size drawing (click on it to see this).

Finally, an archive shot of Mullardoch dam taken shortly after it was completed.
