Dams

Bendora damBendora dam

Bendora Dam

In 1961 Bendora Dam was completed, its construction meant that water could now flow by gravity to Mount Stromlo Water Treatment Plant (WTP). The Bendora gravity main was completed in 1961, and it meant the high cost of pumping could be avoided.

Corin damCorin dam

Corin Dam

Corin Dam is the highest Dam in the Cotter river system. It was completed in 1968, and the water stored in Corin is released into the Cotter River, thereby controlling the level of storage in Bendora Dam.

Googong damGoogong dam

Googong Dam

Googong Dam was constructed after population projections showed that by 1979 the Cotter River system would not be able to cope with the demand for water. After extensive investigations, a site was selected on the Queanbeyan River.

To meet the needs of Canberra people during the establishment years Cotter Dam was constructed in 1912. To meet the needs of Canberra’s growing population the height of the dam was increased in 1951.

Water from the Googong dam storage area is pumped to the adjoining Water Treatment Plant. The treated water is then fed to Canberra's service reservoirs through the Googong bulk supply main.

Catchment areas

Cotter River and Queanbeyan River Catchment

Cotter River and Queanbeyan River Catchment

The Cotter River catchment was the first to be developed and is part of the Namadgi National Park. It serves as a catchment for Cotter, Corin and Bendora Dams. The Queanbeyan River catchment was developed on the Queanbeyan River in NSW. It serves as a catchment for Googong Dam.
