Eucumbene Dam, Embankment dam in Snowy Mountains, Australia

Eucumbene Dam is an embankment dam in the Snowy Mountains that holds back the Eucumbene River to create a large reservoir. The structure uses the region's mountain terrain to store water for hydroelectric power production.

Construction took place from 1956 to 1958 as part of Australia's major water management project. The building work required relocating a nearby town and transformed how water was managed across the entire region.

Lake Eucumbene drowned the old town of Adaminaby; about 800 people moved, and over 100 buildings were re-erected at the new site on the Snowy Mountains Highway. The first house took six days to travel the six miles. The 1958 film Operation Adaminaby and Jeannine Baker's 2001 documentary Our Drowned Town record the move.

The lake offers fishing and boating access from several points around its shore. Visit during dry weather when the roads are easiest to navigate, as mountain conditions can change quickly.

When water levels drop, the ruins of the submerged town become visible through the water. These remains tell the story of the community that once lived here before flooding.
