Prospect Dam

When completed in 1888, this earth and clay-core embankment was the largest dam in Australia.

It was the major component of the Upper Nepean Scheme devised by E. O. Moriarty, Engineer-In-Chief of the Public Works Department, to guarantee Sydney`s water supply. Although the reservoir is no longer the principal component of the present  system, it continues to supply Sydney with water.

Dedicated by the Institution of Engineers, Australia and the Water Board
