Avon Dam

Work on Avon Dam began in 1921. A curved dam with Egyptian style gateways at each end of the crest, Avon is larger than the Cataract and Cordeaux dams combined. The dam's spillway is a concrete serpentine weir with a concrete lined channel situated 400 metres from the left abutment.
All materials were hauled by truck from Bargo on a specially built road. For the first time, electric powered cranes were also used in the construction.
Avon Dam was completed in 1928 and cost about $6.3 million. It was strengthened in 1971 ($3.8m) by buttressing its downstream face with a rockfill embankment.

Nepean Dam

Work on Nepean Dam started in 1925, but was interrupted for a few years by the Depression and resumed in 1933. Materials were hauled on a standard gauge railway line from the main southern line near Bargo.The dam was finally completed in 1935 and cost about $12.3 million. After several years of extremely low rainfall in the catchment, heavy rainfall in October 1938 saw the dam finally reach capacity and overflow via its spillway. Nepean Dam was upgraded in 1992 at a cost of $30 million. It was strengthened by post-tensioned anchors and a downstream rockfill embankment and further safeguarded by a concrete lined side spillway on the right abutment.
