The lake formed by the dam, Lake Burragorang, is one of the largest domestic water supply reservoirs in the world.
The dam wall contains approximately 1.5 million cubic meters of concrete.
During construction, a township was built specifically for workers, which was later dismantled once the project was complete.
The dam's spillway is designed to handle extreme flood events by releasing water into the gorge below.
Water levels in the dam are monitored constantly as a primary indicator of Sydney's overall water security.
The reservoir area is strictly protected to maintain water quality, meaning public access to the water's edge is prohibited.
Warragamba Dam is one of the largest domestic water supply dams in the world, responsible for providing approximately 80% of Sydney's water supply. The dam wall is a concrete gravity structure standing 142 meters high and spanning 351 meters across the Warragamba River gorge. Construction of the dam was completed in 1960 to address Sydney's increasing post-war water demands. The surrounding catchment area spans 9,000 square kilometers, much of which is protected wilderness within the Greater Blue Mountains World Heritage Area. Visitors can access a dedicated visitor center and public viewing platforms overlooking the dam wall and Lake Burragorang. Lake Burragorang, the reservoir formed by the dam, covers 75 square kilometers and has a capacity of 2,027 gigalitres. The site includes educational displays explaining the engineering history and the hydrological function of the reservoir. Walking tracks around the precinct provide views into the deep sandstone gorge downstream from the dam wall.
