Commenced in May 1956 and completed in May 1958, Eucumbene Dam is a major dam, located approximately northeast of the locality of Eucumbene Cove. The dam was constructed by a consortium comprising the Department of Public Works and Kaiser-Walsh-Perini-Raymond based on engineering plans developed by the United States Bureau of Reclamation and the Department of Public Works, under contract from the Snowy Mountains Hydroelectric Authority. Construction of the dam inundated the original township of Old Adaminaby, which was relocated to Adaminaby in the 1950s, requiring approximately 800 people to be moved.
