To whom it may concern,
I am really concerned about the proposal to raise the Warragamba Dam wall. This will flood huge areas of wilderness with a dramatic effect on rare native species.

To whom it may concern,
Please don't ruin our wilderness for the sake of greedy developers🙏🏻

To whom it may concern,
I wish to object to the raising of the Warragamba Dam.

My concerns are threefold. Firstly, and in my view most importantly, the area is still under mapped for Aboriginal cultural heritage. I do not want to have our government repeat the disaster of Rio Tinto in knowingly destroying cultural artifacts of the Gundungarra people.
Secondly, along with that heritage, the area has rich biodiversity that we should not put at risk. We still do not understand the extent of loss that has happened from the 2019/2020 bush fires, so to flood a significant area is planned vandalism.

Finally, the business case for proceeding with raising the wall has not adequately examined other options to mitigate risk of flooding. I believe also that tighter restrictions on further building in floodplains should be introduced.

To whom it may concern,
We live in Emu Plains, one of the areas that could be affected in a 1/100 year flood. Theoretically we should support the wall being raised, but that isn't the case. We knew full well when we bought here that the 1/100 year flood was a risk, and are insured appropriately.
We oppose the dam wall being raised. It will result in devestation of World Heritage Sites, goes against traditional owner wishes, and won't actually help with flood mitigation. The vast majority of run off into the dam causes the flooding, not the dam capacity, and once that occurs water will be released downstream regardless. There has been an inadequate level of information regarding modelling around flooding post the dam wall raising, so we have no data around whether that is even a consideration.
Until such time as reasonable information is released in regards to post wall modelling, as well as adequate environmental and cultural assessments are performed, we remain utterly opposed to any raising of the dam wall, and firmly believe there are alternative means of supporting flood mitigation.

To whom it may concern,
Raising the dam wall is not the solution to servicing the new developments on the flood plain- the way to ensure that people have access to water is to mandate water tanks on every property.
if the water companies are concerned about losing money with this solution they can make the tanks & sell them to the residents.
when large rains fall in the Penrith & Hawkesbury areas none of that water ends up in the dam. This solution prevents unnecessary run off going into the river- which increases the algae in the river & washes chemicals & pesticides all the way along the Hawkesbury/ Nepean river.
Raising the wall and flooding the valley is not in the environmental interests of NSW. There is already mass clearing of land, which is putting our Flora & Fauna at risk of extinction.

Please think of our children's future & the people living in these areas, not the companies who will be increasing the dam.

To whom it may concern, I am a land holder, I pay rates, and I vote. I do not believe that in this time of uncertainty with climate change and with the decline of habitat and our precious wildlife that we should be raising dam's and flooding an ancient ecosystem, please reconsider your proposal and maybe you could fund rainwater tanks for every household it would be alot cheaper and environmentally friendly Thank you for your time.

To whom it may concern,
We don't need more houses we need more green spaces..... we don't breathe bricks and mortar we breath air and trees are essential for our lives.

Good morning,

I wish to state my support for the proposed raising of the dam wall. It is clearly needed for protection of property and will add to supplying water to our growing city.
I am tired of the emotive campaign waged by opponents. Any development has resistance. I encourage the government to proceed with the decision to raise the dam wall.

To whom it may concern,
Don't flood areas of the blue mountains. Find another way to line your pockets without erasing hundreds of years of culture and heritage.

To whom it may concern,
The Blue Mountains World Heritage area is not just a world class National Park, in 2000 it was inscribed on UNESCO’s World Heritage list in recognition of its Outstanding Universal Value for the whole of mankind. Raising the Warragamba dam wall and consequent damage to natural and cultural values would be a clear breach of these undertakings and Australia’s obligations under the World Heritage Convention.
An estimated 65 kilometres of wilderness rivers, and 5,700 hectares of National Parks, 1,300 hectares of which is within the Greater Blue Mountains World Heritage Area, would be inundated by the Dam project. This includes:
• The Kowmung River - declared a ‘Wild River’, protected for its pristine condition under the National Parks and Wildlife Act 1974;
• Unique eucalyptus species diversity recognised as having Outstanding Universal Value under the area’s World Heritage listing such as the Camden White Gum;
• A number of Threatened Ecological Communities, notably Grassy Box Woodland;
• Habitat for endangered and critically endangered species including the Critically Endangered Regent Honeyeater and Sydney’s last Emu population.
• Over 1541 identified cultural heritage sites would be inundated by the Dam proposal.
• The Aboriginal Cultural Heritage Assessment Report has been severely and repeatedly criticised by both the Australian Department of Environment and the International Council on Monuments and Sites (ICOMOS) for not appropriately assessing cultural heritage in meaningful consultation with Gundungurra community members.
