Sacred Waters : The Story of the Blue Mountains Gully Traditional Owners is the moving story of the Aboriginal people in a unique and beautiful part of a Australia- the Burragorang Valley, now profoundly changed by the flooding of the valley in the 1950's by Warragambah Dam, the dam that provides Sydney's water supply. It is the story of the valley's Gundungurra people, and the Darug people of the lower Hawkesbury. Source: Publishers note (Sighted 27/05/2009)
