Loch Glascarnoch Dam, Conon Valley Hydro Electric Scheme

Loch Glascarnoch Dam, part of the Conon Valley Hydro Electric Scheme, was designed by James Williamson and Partners in 1957. This prominent large curved dam is flanked by turfed earth fill wings and features a central control tower along with a fixed spillway that has a vehicular access road running over it. The dam is constructed using mass gravity concrete, with rammed earth wings. It has a battered downstream face and concrete upstand walls to the spillway. The roadway is supported by tapered concrete piers, with a single larger rectangular pier at the center above the dispersal valve, and a plain parapet above the fixed spillway.

The control tower is a tall rectangular structure located at the center of the dam, featuring a two-storey and attic section that is visible above the dam wall. This tower houses the control gate for the dam's dispersal valve and is made of reinforced concrete with band courses and a banded eaves course. There is a large vehicular access doorway on the southeast side, with a single attic storey window above it. The tower has irregular fenestration with small pane metal glazing set in metal surrounds.
