Lockyer Valley residents, who bore the brunt of the inland tsunami that ripped through rural districts and small towns tearing their lives apart and leaving 17 people dead, are left with many questions despite the release yesterday of the Queensland Floods Commission of Inquiry’s interim report on flood preparedness.
Installation of more rain gauges high in the catchment linked to the Bureau of Meteorology to give the earliest possible warning of flooding and automatic sirens warning of sudden stream rises, as suggested by many flood survivors, have been welcomed.
So too have recommendations that the local creeks be cleared of the hundreds of tons of debris that have been left rotting in the creeks and choking the waterways.
A hydrological study into the effect of a large earthen wall around a creek pocket to protect a sand quarry from flooding has also been welcomed.
But the biggest question for people who lost family members and friends in the disaster on January 10: “why did they die?” has been left unanswered.
Importantly for many residents, finding out who is responsible for the deaths of people in their own homes, totally unaware that they and their children were in danger, is still a burning question that keeps them awake at night.
The finding that the Lockyer Valley Regional Council is not responsible for the deaths has left some residents distraught.
“Someone has to be responsible,” Grantham resident John Gallagher said.
Meanwhile, the police search for three remaining missing bodies continues.
New flood debris is still surfacing in farm dams. Local people who have seen so many victims of the flood buried know the excruciating pain endured by families whose loved ones are still missing.
They need to get them back and have a funeral.
Some of the most severely affected residents believe that absolving any organisation of blame so soon after the disaster and before any coronial inquests into the causes of death is premature and leaves the community vulnerable to the same catastrophic weather conditions in future possibly leading to the same raft of tragic consequences — lives lost and homes and livelihoods destroyed.
Locals point to a Facebook post by the council at 1.50pm on January 10 that “There has been some major flash flooding around the Murphys Creek and Withcott areas with water flowing heavily across the Warrego Highway at Withcott”.
They claim the council, which is responsible for warning of flash flooding, failed to connect that the huge amount of floodwater would threaten a town of hundreds of people.
But opinion is divided with other residents believing council could not have foreseen the disaster.
At the local shop, still working from a temporary building, owner Sandy Halliday has not had time to read the interim report and she doesn’t talk to customers about the flood because it’s still such an emotive and divisive subject.
“No one said anything about it. We try not to get into the sh-t,” she said.
Local flood volunteer Terri-Ann McLachlan who has distributed hundreds of thousands of dollars worth of private donations directly to more than 50 flooded families, said opinion was divided on the usefulness of the report.
“It’s all a bit too late but anything would be better than nothing. People who have lived through it are more aware,” she said.
“Any water that comes now and they are going to get out. They are going to run for it without trying to save their possessions and animals.”
“The council is going to put in flood gauges with alerts, but what level is too high?” she asked.
Residents of Grantham and farmers upstream of the town have welcomed the appointment by the Flood Commission of hydrologist Dr Philip Jordan to create a hydrological model to determine the possible effect of a sand and gravel quarry, on the flow of the huge volume of 4000 cubic metres per second of water down Lockyer Creek as it headed for Grantham.
Dr Jordan has recently spoken with residents who live on farms around the quarry, gathering information from witnesses who fled on the day of the flood when they saw floodwater begin to pour over the quarry wall and gush metres deep across their farms.
His findings are not included in the interim report.
While residents have welcomed the hydrology study, they also want the Flood Commission to return to the town and hear directly from the many people who saw what happened on the day.
Dozens of people in the centre of the disaster zone are still living in sheds, shipping containers, buses and flood-damaged houses. They were so busy patching back together what was left of their lives and properties that they could not make submissions to the inquiry.
They have not yet been heard and there are no plans for any further hearings of the inquiry in Grantham.
Local resident John Gallagher is waiting for the hydrology study findings, since his property had never been flooded before, even in the record 1974 flood.
“I don’t put a lot of faith in early warning systems. There was no time. We need the creek not to get out of the creek,” he said.
Had the creek remained in its channel, Gallagher believes, the flood in Grantham would have been a “slow flood”, giving people time to escape. It would not have been a violent deadly one.

August 2, 2011 at 4:24 pmSuzanne Blake to equate Warragamba dam with Wivenhoe just betrays ignorance.

August 2, 2011 at 4:27 pmOne suggestion that I have heard that is absolutely crazy is to increase the size of the Wivenhoe Dam. Why? To increase its effectiveness as a flood-mitigation tool.
That sounds mighty stupid to me. Isn’t the Wivenhoe Dam already the single-biggest TERRORIST TARGET in Australia?
If a Wivenhoe Dam after heavy rains that filled it up to 190% (As it did in January) was to be blown up by terrorists – what would be the consequences for Brisbane? The city would be underwater – and yet Campbell Newman is talking of increasing this risk by increasing the size of the dam!
Madness.
Far better to spread the load by building other dams. Down here in Victoria we have several dams – none as big as Wivenhoe and none that pose a significant risk to the city of Melbourne were they to be blown up.
Comparing dams in and around Brisbane and Melbourne by size (Above 25,000 ML)
Wivenhoe – 1,165,238 ML (Brisbane)
Thomson – 1,068,000 ML (Melbourne – but nowhere near the city)
Somerset – 379,849 ML (Brisbane)
Cardinia – 286,911 ML (Melbourne)
North Pine – 214,302 ML (Brisbane)
Upper Yarra – 200,579 ML (Melbourne)
Hinze – 161,073 ML (Brisbane)
Sugarloaf – 96,253 ML (Melbourne)
Baroon Pocket – 61,000 ML (Brisbane)
Silvan – 40,445 ML (Melbourne)
Tarago – 37,580 ML (Melbourne)
Yan Yean – 30,266 ML (Melbourne)
Greenvale – 26,839 ML (Melbourne)
Clearly in Melbourne there are more dams around the size of 25,000 – 100,000 ML than in Brisbane. Rather than enlarging the Wivenhoe (Australia’s Number 1 Terrorist Target?), Brisbane should construct more reservoirs between 50,000 – 100,000 ML if it needs more water or better flood mitigation.

“The whole idea of a dam is to save water and spill it as needed to avert a flood. ”
The dam in question had a priority to provide water and flood mitigation was a secondary consideration. That was the charter that its operators went by and which they followed. How high can you make levies etc is as good as saying how long is a piece of string. 9 metre sea walls were thought safe for Japan towns but have proven not so safe in extreme circumstances. Build higher or move the town a safer distance ?
Now which insulation death do you consider the first ? Seeing as you like trotting that scenario out at every opportunity name what date you want to start. 1980 or 1990 could be relevant regarding industry standards and regulations but I,m only guessing. A charge of industrial manslaughter may have got a few in the insulation industry to ensure standards were adhered to but you apparently don,t like that idea. I have an old fashioned idea of business in that a householder has a contract with an insulation company and that company agrees to insulate at an agreed cost a safe product. The state makes standards and rules for these companies to adhere to to ensure safe insulation plus protection for workers.
You make gratuitous remarks about 4 deaths but never as regret for the loss of life but as a tool to assault the government. You don,t investigate the fact that fatalities occurred many years before the stimulus package insulation scheme. A million odd homes insulated and mostly done by competent installers who achieved the job within the mean average for deaths and fires per number of buildings insulated. None of that concerns you because someone must be at fault and that someone must be a Labor government. Employer negligence or extreme climate conditions are mere red herrings to be cast aside in your quest to blame Labor. I hope you are a troll because it would be a very sad existence otherwise.

I just dont have the blinkers on and have my head in the sand.
You cant be serious? “dam in question had a priority to provide water and flood mitigation was a secondary consideration”
All dams provide water, some flood mitigation, some hydro, some both?
You mean to state that the Dam Operators in Queensland are stupid and not caring for life? Hope you get to front the Commission and justify that.
9 metre walls in Japan, were thought to be safe when? 1960’s 1970’s, 1980’s, 1990’s or 2000?
The Sydney Harbour Tunnel was ‘built to withstand a ship sinking on it’ Is this true? was it true when built, is it still true today? Same with cracking in airframes.
Your logic – will see people die and has seen people die.

There were two women interviewed on the 730 Report on ABC last night that said the 60+ minute warning could have saved many lives. They live there they should know. Dont you think?

August 2, 2011 at 5:53 pmLives and property were lost by a combination of (1) natural events, (2) peoples’ mistakes and (3) preventative action which people didn’t take but which they would now do in hindsight. Much of the discussion so far has been people disagreeing about the relative importance of 1, 2 and 3.
I give more weight to (1) than some of the people quoted in the article and some of Crikey’s posters, but the search for (2) and (3) stimulates human inventiveness and improvement. It may therefore result in benefits which a fatalistic acceptance of (1) may miss.
In the end I would want to balance the cost of any preventative measure against the risk and cost of a recurrence of a flood and against the benefits from additional allocations to other goals, such as improving Indigenous Australians’ health or relieving poverty in Somalia.

August 2, 2011 at 6:56 pm@Suzanne Blake all your examples only make sense in hindsight. I can tell you last week’s lotto numbers and say you should have picked them but will it do you any good? Are you going to blame me for not having told you them in time? I mean you’d be rich if I had.
Coulda woulda shoulda as the yanks say.

Hindsight, you mean foresight?
The former with sleepy bureaucrats / government, the former with smart people.
I would bet people with your notions have never run a successful company nor will.

August 2, 2011 at 8:45 pmWhy does no-one not mention catchment land-clearing? Without a denuded landscape such floods wouldn’t spread across the landscape so quickly. But has that sunk in? – I think not if this is anything to judge by: –
“So too have recommendations that the local creeks be cleared of the hundreds of tons of debris that have been left rotting in the creeks and choking the waterways.” Choking the waterways!?!? mmmm…. slowing the flow of water?
But it’s all blame, blame, blame in the new whingeing Australia, with people apparently even “distraught” that “the Lockyer Valley Regional Council is not responsible for the deaths”. How awful that someone can’t be blamed.
And at the risk of feeding the troll, could someone with some numbers to hand please point out the utter difference between the volume of water flowing behind the Wivenhoe dam and the capacity of the dam? There’s a point when a dam, no matter how big, is going to be useless.
Plant trees over your cleared land people, don’t live in flood zones and be prepared! …
I live in a flood zone – and my house has been flooded over a metre right through in the last five years – I have a flood plan and I don’t blame someone else for the flooding when it happens. Sure, there’s things we could do to mitigate it, but at the end of the day we should know the conditions of where we live and take responsibility for our choices.

August 2, 2011 at 9:11 pmBob,
from what I have read on the commission report, very basic brief modelling suggested dropping the storage level to 75 % would have had a noticible reduction in peak instantaneous flow rate discharging from the dam. There is no discussion I saw about what the peak flow rates at critical points would have been or what impacts this would have had on loss of life.
There is also a brief statement to the effect that SEQWATER suggested significant reductions in full storage level would be required to reduce the ‘magnitude’ of the flooding. I haven’t come across a description of what ‘magnitutde’ means in this instance. My interpretation is that SEQWATER is saying that it will reduce peak velocity but have little impact on flood depth and hence flood extent.
Loss of life is generally associated with peak velocity but the modelling isn’t comprehensive and the statements of findings in the report are even less so.
None the less, as an engineer who has spent his entire career involved in hydraulic and hydrological modelling I can’t help but feel that people focussing on the decisions about releases is largely misguided.
The majority of loss of life was in the Lockyer valley and dam levels had no baring on this. Also as someone who deals with community attitudes towards water supply security, I think people need to have a long hard look at themselves and realise that the reluctance to release water from the dams was driven by community attitudes in relation to maintaining water supply.
I would have to say that I agree that undoubtedly more could have been done, but like others pointed out, more can be done in education, more can be done in health, alot more can be done in terms of poverty in other countries. Its always a cost benefit decision, whether directly or indirectly and the amount the community is willing to pay drives what gets done.
Beuracrats have a role to play and don’t always get it right, but the community pays the bills. If you want more models, more flood warning, more emergency management plans, someone has to pay overpriced consultants like me to produce the outputs. So I change my mind, we should be doing ALOT more and everyone should be paying 🙂
