Lake Eucumbene is an artificial reservoir in the Snowy Mountains of New South Wales, Australia. It was formed by the Eucumbene Dam, which provides the major regulating storage for the Snowy Mountains Hydro-Electric Scheme. The dam was completed in 1958. The first diversion of water from Lake Eucumbene to the Tumut River was accomplished by the completion of the Eucumbene-Tumut tunnel in 1959. The Murrumbidgee-Eucumbene tunnel began operations in 1961.
The first stage of the Snowy-Murray development was the Eucumbene-Snowy project, involving the construction of Island Bend Dam and the Eucumbene-Snowy tunnel. It began diverting water from the Snowy River into Lake Eucumbene in 1965.
The nearest large town and railhead is Cooma. Tourist activities include launch excursions on the lake, trout fishing, and camping. Tourist resorts include Buckenderra, Old Adaminaby, Illawong, Providence, and Braemar.
