Population projections showed that by 1979 the three existing dams on the Cotter River would not be able to cope with the increasing demand for water. A new water source was required and, after extensive investigations, a site was selected on the Queanbeyan River and Googong Dam was constructed.
Googong Dam is an earth and rockfill embankment dam with adjoining converging chute spillway and a nearby 13 metre high earthfill saddle embankment. It was completed in 1979, and upgraded in 1995 and again in 2010 through the Googong Dam Spillway project.
Storage Capacity: 119,400 million litres
Top water level: 663.0m above sea level
