This barrage regulates the flow from Loch Ken before feeding it into the Dee River to feed down to Tongland Loch (see separate record). This is the main regulation for Tongland powerhouse as Tongland Loch has insufficient capacity to mediate fluctuation in flow. Flow is controlled by 3 Glenfield Roller gates and a central fish pass. Machinery to operate the gates is located on an overhead steel gantry. This is a good example of the use of a barrage as distinct from a dam. The barrage is a very precise engineering response to the particular geographic and hydrological conditions at this point on the river. A dam would not have been appropriate on this site because of the high instance of flood at this site. The barrage is a striking landscape feature and retains its original fixtures and fittings, including barrage gates and winding gear. P L Payne, 1988; E Wood, 2002; G Hill, 1984.
