The Scheme comprised two main parts i) The Snowy Murray Development, which involved the diversion of the Snowy River, and ii) the Snowy-Tumut Development, which involved the diversion and damming of the Eucumbene River. This water storage was initially called Adaminaby Dam, Reservoir or Storage and was seen as the heart of the Snowy Mountains Scheme. The name was then changed to Eucumbene Dam, now known as Lake Eucumbene.
