Whiteadder Reservoir is a reservoir in East Lothian, Scotland, UK, in the Lammermuir Hills, 11 miles (18 km) north west of Duns in the Scottish Borders, and five miles (8 km) south east of Garvald. It was created to provide additional water facilities for East Lothian.
Work on the Dam forming the reservoir commenced in 1964.[1] Design was carried out by consulting civil engineers GH Hill & Sons of Manchester and London, on behalf of the then local water authority - East Lothian Water Board. The flooding ceremony was in May 1968. Millknowe Farm and Kingside School were flooded.
Whiteadder reservoir supplies East Lothian and Berwickshire, including the former Cockenzie Power Station on the northern coast of East Lothian, the Whiteadder Water flows out of the reservoir and is the lowest tributary of the River Tweed which it enters at Berwick-on-Tweed. In 2023, a 200kW hydro-electric plant was commissioned, providing power to the "Hungry Snout" water pumping station.
