Cordeaux Dam

Historical Sites and Heritage Locations

Cordeaux Dam may be impacted by bushfires in the region. Please note that conditions in Wollondilly may change over the Christmas period. Before undertaking any travel, please visit the NSW Rural Fire Service website to check affected areas and road closures.

Cordeaux Dam was completed in 1926 and was the second of the Upper Nepean dams. It is 57 metres high, holds water from a 91 square kilometre catchment, and forms a lake of 780 hectares with a capacity of 93,640 megalitres. Take a look at the valve house and pylons, built in a Neo-Egyptian style.

The dams of the Upper Nepean collect water from the catchments of the Cataract, Cordeaux, Avon and Nepean rivers, which are tributaries of the Upper Hawkesbury-Nepean River. These systems supply water to the Macarthur and Illawarra regions, the Wollondilly Shire, and metropolitan Sydney.

Facilities include picnic shelters, electric barbecues, drinking water, toilets, disabled toilets, playground and viewing areas. Bookings are required for groups of 50 or more.
