A report on the warragamba dam

Trees were cleared from the Burragorang Valley, and two temporary coffer dams and a tunnel were built to keep the site dry. A tall and narrow dam capable of holding a vast amount of water could be built.

Although the engineers did not design Warragamba Dam as a flood control measure, it can mitigate flooding by holding floodwaters back while the reservoir fills.

Later improvements To meet modern dam safety standards, in the late s the dam wall was strengthened and raised by five metres. It was an engineering masterpiece of the midth Century - and it still takes your breath away today. Taylor Clarke is fighting to protect what Indigenous heritage is left.

Water NSW is currently undertaking environmental assessments for the proposal to raise the dam wall by 14 metres in order to mitigate floods in the Hawkesbury-Nepean Valley through temporary water storage and controlled A report on the warragamba dam of floodwaters.

Relax with a picnic Relax with family and friends in the landscaped grounds. During a long cross-country battle in the Dreaming Gunyungalungthe deep gorges of the Burragorang Valley were gouged out. Browne found a more suitable site and continued as geological adviser until completion.

Step back in time Take a self-guided walk around the dam grounds and discover the history of this monumental undertaking. The dam was built in a series of large interlocking concrete blocks. This new outlet was below the minimum level required for gravity flow, which delivered water from the existing outlets.

In it suffered damage in a bushfire and was subsequently demolished. Nick Moir Mr Debus will be attending the next meeting of the WHC in Bahrain at the end of the month, where he will be lobbying delegates and the committee to put a stop to any approvals until the middle of next year.

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.

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.

Between and the catchment area experienced extremely low rainfall, and on 8 February it recorded an all time low of 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.

Step into the future Step inside the modern visitor centre and enjoy an even better view of 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.

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.

The resulting dam of the Warragamba River formed Lake Burragorang, which is one of the largest reservoirs for urban water supply in the world.

Warragamba Dam: NSW Government accused of attacking world heritage, moratorium demanded

The lake created by the dam stretches back 52 kilometres from the wall. In the Warragamba River was diverted so excavation for the dam could start. Between andsupporters proposed various schemes before the site and design of the current dam received approval. In the flooding of the Burragorang back in the 60s my family had to leave Ina weir and pumping station, known as the Warragamba Emergency Scheme, reached completion, just downstream of the main dam site.

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. The drum gate is hinged along the upstream edge to the upstream crest and lowers into the dam wall to allow water to flow over it.

The area proposed for inundation includes up to 1, hectares of world heritage property and 3, hectares of land within the adjacent Warragamba Special Area, the letter states. No wood, charcoal or solid fuel barbecues.

Nearby, Eighteenth Street Lookout provides the best view of the height of the dam wall and auxiliary spillway. One was to add ice to the wet concrete, the first application of this technique in Australia.This report was prepared by S.T.

The NSW Government is accused of an extraordinary attack on a world heritage area in the Blue Mountains, putting hundreds of significant Indigenous sites at risk with their plan to raise the Warragamba Dam.

Warragamba Dam In the area of Sydney, Illawarra and the Blue Mountains a total population of 4 million they all rely on the catchment of five major river systems- Warragamba, the Upper Nepean, Shoalhaven, Blue Mountains and Woronora.5/5(3).

Look out at Warragamba Dam and see the past and future of Sydney's water supply.

Warragamba Dam supplies water to more than million people living in Sydney and the lower Blue Mountains. Just a one hour drive from Sydney's CBD, the dam is a popular place to visit and picnic. This is a report on a set of tests on the "Physical Properties of Rock in Foundation and Abutment", for the proposed Warragamba Dam, conducted at Sydney University under the supervision of Mr H.J.
