The Warragamba Experience

Top 5 things to see and do

1. Be photographed with the 'quiet beast'

Stand on one of the viewing platforms and have your photo taken with the 'quiet beast'. Warragamba Dam's nickname comes from the fact that three million tonnes of concrete is holding back four Sydney Harbours of water, yet the atmosphere is calm and peaceful. It was an engineering masterpiece of the mid-20th Century - and it still takes your breath away today.

2. Step back in time

Take a self-guided walk around the dam grounds and discover the history of this monumental undertaking. Interpretive signs and heritage items along the way reveal the stories behind the dam's construction. Pause at the Workers' Memorial and pay your respect to the 14 dam builders who died during construction.

3. Soak up the views

Gaze down upon the dam wall and a small part of Lake Burragorang from the deck of the magnificent visitor centre, perched high on a rocky outcrop, or head down to the dam wall on weekends and public holidays ONLY for a close up view of the Lake. The lake created by the dam stretches back 52 kilometres from the wall. Nearby, Eighteenth Street Lookout provides the best view of the height of the dam wall and auxiliary spillway.

4. Step into the future

Step inside the modern visitor centre and enjoy an even better view of the dam. Take a journey through the water cycle in the 'Water for Life' exhibition. Be amazed by the unique 'drops of wisdom' interactive table. Don't miss the children's activities, and ask our friendly visitor centre staff your questions.

5. Relax with a picnic

Relax with family and friends in the landscaped grounds. Throw down a rug and picnic under a shady tree or use one of our tables or shelter sheds. Drinking water and modern toilet facilities are scattered throughout the grounds. Barbeque facilities and a children's playground are located at the adjacent Warragamba Recreation Reserve managed by Wollondilly Shire Council, and Warragamba township has cafes and shops for hot drinks and meals.


Permanent and temporary exhibitions are showcased in the impressive Warragamba Dam Visitor Centre, which perches on a rocky outcrop high above the dam wall.

The centre's Burragorang Room boasts sweeping views of the lake, children's activities and video presentations. Friendly visitor centre staff are available to answer your questions.

Permanent exhibition - 'Water for Life'

'Water for Life' is a highlight of any visit to Warragamba Dam. This permanent exhibition tells the story of Sydney's dams and catchments, and the history and future of Sydney's water supply.

As you enter the exhibition, look right to check out the latest levels at each of Sydney's 14 water supply dams, including Warragamba. Then follow the circular path clockwise to trace the journey of your water.

Don't miss the interactive 'drops of wisdom' table where you can get your hands 'wet' as you discover some of the unusual facts and myths about the dam and surrounding bushland. (See rare footage of emus doing a mating dance!)

Stop and listen to some stories from the local and migrant workers who built the dam and its township. Watch the audio-visual displays and inspect artefacts from the Indigenous and settler residents of the Burragorang Valley.

Along the way you can trace the history of Sydney's water supply, from its humble beginnings with the Tank Stream in 1795 to Prospect Reservoir in 1888, through to Warragamba Dam in 1960 and today's water recycling and climate change planning.

Current temporary exhibition - Underwater Warragamba

The waters of Lake Burragorang, formed by Warragamba Dam, are a hidden world full of life and diversity. Sheltered bays and shallow inlets, where creeks and rivers flow into the lake, are an ideal habitat for native animals such as turtles, platypus and water rats. Deeper below the surface, the lake is a haven for native fish and crayfish, and the long-finned eel whose remarkable migration journey takes them to Vanuatu to breed. This journey of endurance is matched only by the return trip of the tiny eel hatchlings which detour up and around the dam wall to return to the lake.

So visit the Warragamba Dam Visitor Centre now to:

  • Meet some of the creatures who call Underwater Warragamba home.
  • Watch the short film to learn how our scientists ensure the best quality water.
  • Make a journey of a lifetime with the Long-finned eel.
  • Follow the footsteps of the Dreaming creatures who carved out the Burragorang Valley.
  • Marvel at remnants of valley life that lie in the watery depths of the lake.

Facts & History

Located about 65 kilometres west of Sydney in a narrow gorge on the Warragamba River, Warragamba Dam is one of the largest domestic water supply dams in the world.

Created by damming Warragamba River and flooding the Burragorang Valley, the storage lake is four times the size of Sydney Harbour and stores around 80 percent of Sydney's water.

How the dam works

Warragamba Dam supplies water to more than 5 million people living in Sydney and the lower Blue Mountains.

The best quality water is selected and drawn through screens on three outlets in the upstream face of the dam. Water flows by gravity through a valve house into two pipelines that feed the raw water to Prospect water filtration plant and via off-takes to smaller filtration plants at Orchard Hills and Warragamba.

Early history

A local Gundungurra Aboriginal creation story tells of two dreamtime spirits Mirragan - a large tiger cat, and his quarry Gurangatch - a part fish part reptile who lived in a lagoon where the Wollondilly and Wingecarribee rivers meet. During a long cross-country battle in the Dreaming (Gunyungalung), the deep gorges of the Burragorang Valley were gouged out. It was this valley that was flooded when Warragamba Dam was built.

The location of the dam was first suggested in 1845. The deep narrow gorge of the Warragamba River, at the exit to Burragorang Valley, was identified as an ideal place for a dam by Polish explorer Count Paul Strzelecki. More than a century and many droughts later, work finally started in 1948 to build a reliable new water supply for Sydney's growing population. It took 12 years and 1,800 workers to build the dam, which opened in 1960. It was such a major undertaking that a town was built next to the site to house the dam builders.

Why the dam was built

The Warragamba River offered two important advantages as a site for a major dam - a large catchment area, and a river flowing through a narrow gorge. A tall and narrow dam capable of holding a vast amount of water could be built.

A population boom after World War I followed by the worst drought in recorded history, from 1934 to 1942, placed immense pressure on Sydney's water supply. However, despite the first sketch plans for Warragamba Dam being drawn up in 1867, plans were deferred during the construction of the Upper Nepean dams (1907-35), the Great Depression (1929-32) and World War II (1939-45).

How the dam was built

Warragamba Dam was a major engineering feat of the mid-20th Century. In 1946 the Warragamba River was diverted so excavation for the dam could start. Trees were cleared from the Burragorang Valley, and two temporary (coffer) dams and a tunnel were built to keep the site dry. More than 2.3 million tonnes of sandstone was removed.

Concrete was mixed on site using 305,000 tonnes of cement and 2.5 million tonnes of sand and gravel. The sand and gravel was transported from McCann's Island in the Nepean River via an aerial ropeway.

The dam was built in a series of large interlocking concrete blocks. Overhead cableways lifted 18 tonne buckets to place the concrete. Ice was mixed with the concrete to control heat generation and prevent cracks. One of the first pre-stressed concrete towers in Australia was built to house the ice-making plant.

To get to the work site from Warragamba township, the dam builders used two suspension bridges, one across Folly Creek, upstream of the dam wall, and the other across the Warragamba Gorge just downstream from the dam. These Folly Creek bridge was removed after the dam was built but the bridge over the gorge was kept and incorporated into the beautification works at the dam. In 2001 it suffered damage in a bushfire and was subsequently demolished.

Later improvements

To meet modern dam safety standards, in the late 1980s the dam wall was strengthened and raised by five metres. In the early 2000s an auxiliary spillway was built to divert floodwaters around the dam in a rare and extreme flood so as to protect the dam and ensure it remains safe in an extreme flood. A deep water pumping station was established in 2006 to allow water to be accessed lower down in the lake during times of drought.
