Warragamba Dam

Warragamba Dam is a heritage-listed dam in the outer South Western Sydney suburb of Warragamba, Wollondilly Shire in New South Wales, Australia. It is a concrete gravity dam, which creates Lake Burragorang, the primary reservoir for water supply for the city of Sydney. The dam wall is located approximately 65 kilometres W of Sydney central business district, 4½ km SW of the town of Wallacia, and 1 km NW of the village of Warragamba.

The dam was devised as part of a collective engineering response to Sydney's critical water shortage during World War II and was originally known as the Warragamba Emergency Scheme. Constructed between 1948 and 1960, the dam created capacity for a reservoir of 2,031 gigalitres and is fed by a catchment area of 9,051 square kilometres.
