Dear Senator Wong,
In your address to the 4th Annual Australian
Water Summit earlier this year, you stated that
“a key element of Water for the Future
is to work with the States to develop new sources
of water that do not rely entirely on rainfall.”
This is essential.
I also share your view that ‘the most
pressing challenge is to ensure all Australian
governments are responding to the impacts of
climate change on our water supplies and the
health of our rivers.’
I am concerned by the Queensland Government’s
plans to build Traveston Crossing Dam on the
Mary River. If it had been operating during
2006/2007, flows to the Great Sandy Strait would
have been reduced to less than 25% of the natural
state. Yet the Queensland Government says the
Great Sandy Strait, Hervey Bay and Fraser Island
would not be affected.
The impacts on the Great Sandy Strait and RAMSAR
wetlands have not been adequately addressed.
Rainfall is predicted to decline and if it were
to fall by only 10%, stream flows into the dam
would be a cut by a third. Further reductions
in environmental flow would be inevitable.
If we are serious about reversing Climate Change,
the Queensland Government should be aiming to
minimize emissions of methane, a greenhouse
gas far more potent than carbon dioxide. It
has been estimated that aquatic weed infestations,
drowned vegetation and pumping to Brisbane add
up to more greenhouse gas emissions than a coal-fired
power station.
Already, worrying trends across the last decade
have seen the Mary River flows cut by around
half, similar to what has occurred in the Murray
River system. We cannot allow government to
Murray the Mary.
The Queensland Water Commission sees Traveston
as the last dam to be built in Queensland before
turning to desalination plants. I ask your help
to assist the state government to fast-track
more environmentally sustainable alternatives
to the dam and to allow the Mary to continue
to function as a healthy waterway.
It would be tragic if your government were
to espouse such noble aspirations and then cave
in to the Queensland Government’s misguided
determination to build this dam.
