Dam a 'disaster for all'

THE Queensland Government has for the first time admitted its proposed Traveston Crossing dam would be an environmental, social and financial disaster, all the way downstream to Hervey Bay and Fraser Island.

And, according to Gympie Regional Council Works Committee chairman Larry Friske, associated sewerage disposal problems could send the council broke.

Tighter Environmental Protection Agency requirements for effluent disposal came as an ironic counterpoint to the same agency’s admissions, revealed yesterday, that council would have to plan for periods of “zero flow of the Mary River due to the Traveston Dam”. In a further irony, the EPA has also rejected, on river health grounds, a council plan for land-based disposal.

“I must admit it came as a surprise that a government organisation has identified that there will (sometimes) be no flow in the Mary River as a result of the dam,” Cr Friske said.

Mayor Ron Dyne said: “I am amazed that a government department has come up with this, because I was assured in all our discussions that there would be a substantial flow in the Mary River.

“If we have to find another way of disposing of effluent (it will cost money),” he said. “If we think we’ve got a tight budget in coming weeks, it’s going to get worse.”

Finance Committee chairman Cr Donna Neilson said: “That’s a cost from the dam that we haven’t allowed for.”

Cr Dyne said: “I have a sneaking suspicion there’ll be a release from the government saying it’s not accurate”, to which Mary Valley councillor Jan Watt responded: “I suspect it is accurate though”.

Cr Friske said: “If we have reduced flow or zero flow at Gympie, what ends up at Hervey Bay?

“If the government is saying zero flow, then they are going to destroy Hervey Bay and all the fish breeding and prawn breeding the Mary River spawns, by building this dam.”

Irrigation farming would also be devastated if dry periods were marked by zero flow in the Mary River, Crs Ian Petersen and Graham Engeman said.

Cr Watt said it was the first time the government had revealed this information.

Cr Dyne said environmental protocols were a big cost.

“People have to realise we have to find the dollars and cents to fund these requirements, which seem to come out as a daily event.”

Cr Friske said council faced limited options for sewage disposal “if we can’t put it into the river”.

“You can’t put it on dairy paddocks or crops where it could get into food. It’s simply going to break us,” he said.

He said the dam was now revealed as “an ecological disaster right down the river. If they don’t allow us to put some (treated effluent) back, we’ve got a financial disaster too”.

Cr Watt said the dam’s Environmental Impact Statement, prepared by dam construction company Queensland Water Infrastructure, had claimed 85 per cent of the river’s flow would be unimpeded. Engineering director Bob Fredman said council had tried hard to find alternative means of disposal, including using the river as a conduit to sugar paddocks towards the northern part of the old Cooloola Shire.

“But we are not allowed to use the river as a conduit,” he said.

“The new treatment plant will greatly improve the quality of effluent, but as fast as we improve it, the noose tightens with new restrictions.

“This is one of the few times the EPA has commented on the dam and it is significant,” he said.

The book should be laying flat for better scale, and lose the high hills.
pretty funny though.

The government is caught out here.

They claim to leave 85% of the flow happening.

Not being a scientist I don't know how this will affect nature, but it must have some effect just as if I only had 85% of my blood flowing through my veins would effect me.

However it is not that simple. The 85% figure is total flow averaged over the years - which means in some years and months it will be flooding down the river over a full dam (not just flushed out to sea as a waste as Anna and her gang say) and others, like last year it may be dry - it is then that zero flow is a possibility.

The government has been proud to say, "If this dam had been built it would have filled 6, 7, or X number of times!" - does this also mean it would be emptied 5, 6 or X-1 number of times?

One of the many things they do not make clear is that the majority of the 85% flow of the river will be during the flooding times - ohh durr the river is a thousand times bigger during these events.

So when they get the next damful of water, is it emptied before they fill it again? or to put it another way,

How many damfulls of water can they get in one flood event?

I can only come up with the answer, "One damfull".

So where are they going to get all the other water they need to justify this expensive monstrosity?

ANSWER: DURING THE TIME WHEN THE RIVER IS A TRICKLE AND IN THE DRY AS WELL.

WILL THEY EVER HAVE ZERO FLOW?

Same answer as -

IS THE POPE A CATHOLIC?!!!

I hope this government never gets to regulate the amount of blood going through my veins.

"Good news Mr Watt, today we will be changing your blood 7 times - we believe you will need this for next week we are taking it all - but don't worry during this time your blood will be keeping all the other..."

Whatever.

Sustainability Minister Anndrew McNamara should either resign his cabinet portfolio or become the Minister for development in the Bligh cabinet.He certainly does nothing to protect our precious environment..ISS OR GET OFF THE POT.....Dave.

Facts stack up for Mary River dam

There has been an abundance 'of name-calling, misinformation, scare-mongering, political point scoring and just plain silliness over the past weeks regarding the proposed Traveston Crossing dam.

I'd like to take this opportunity to state some facts.

There has never been an EPA report that projected zero flows of water below the proposed dam.

There was a letter, written by an administrative officer at the EPA to the Gympie Regional Council, that said if they were planning to put effluent into the river they should plan for zero flows as a result of the dam. The letter was a mistake, pure and simple.

The facts about the Traveston Crossing dam are, as they have long been, that Stage 1 will have taken less water from the Mary River by the time it reaches the ocean than is already being taken by irrigation and industry - just 4% on average each year.

As the dam will be more than 200km upstream from the river's mouth, with several major tributaries in between, it would not increase the silt flow of the Mary, a flow that is largely a result of land clearing throughout the catchment.

It will provide flood mitigation for Gympie by capturing some flood flow and releasing it at a lower rate, while still allowing plenty of flushing flows along the length of the river.

Even after the dam is built, the Mary will be the least utilised major river in Queensland. The dam will take only 70,000 million litres of water each year, leaving, on average, more than 2,200,000 billion litres of water flowing to the mouth of the river. Seventy-eight per cent of the river's catchment is downstream of the dam wall.

The Mary catchment was listed in a recent report as one of the regions in Queensland where rainfall will be least affected by climate change.

My position on the dam has never changed. I said that I would support it if the environmental impact statement stacked up. The EIS for Stage 1 does stack up.

Further stages of the dam are not projected to go head until 2035, and only then if required by demand.

Andrew, if you're reading this, I have some comments...

Yes - correct. Most of the name-calling, misinformation, political point scoring and just plain silliness has come from YOU! Calling Gympie Mayor Ron Dyne a liar re: the EPA report, which is now a matter of public record. You are an incompetent clown. Sue me for name-calling.

Quote:

Dissembling. The EPA document talked about "reduced or no flow". It may have been in the form of a letter, not a report, but it was a formal response on behalf of the EPA to an application by the Gympie Regional Council.

Quote:
The letter was a mistake, pure and simple.


Well, No. It wasn't. The IQQM River flow modelling results, included as an appendix to the EIS, show that the flowrate at Fisherman's Pocket (monitoring node closest to, and just downstream of Gympie):
- will be zero - "0" - "the big O" - approximately 1% of the time
- will be less than 100ML per day (equivalent to about 10cm depth) over 35% of the time, and
- will be less than 350ML per day (equivalent to about 30cm depth) over 68% of the time.

Maybe that's why these results are hidden away in 6,000 pages of numerical data, in an obscure Appendix, with no summary information provided.

Yes, about 1.5 metres high if you include the Appendices.



There are many other holes in your newspaper article, Minister McNamara, but this last one is my favourite. You claim to be taking the "opportunity to state some facts".

But you write:

Quote:

Somebody has their millions and billions confused, Andrew. Those big numbers can be hard, can't they? It reminds me - did you hear about the three Brazilian tourists who are going to cancel their fishing holiday to Hervey Bay this year? Go and ask your spin doctors to help you figure out how many is a Brazillion.
