If ever their was an example of a shared delusional disorder it is the belief that the Clarence River system has spare capacity to sustainably water share with the Murray-Darling Basin......
The Chronicle, 4 September 2019, p.16, excerpt:
Southern Downs: The Southern Downs Regional Council has endorsed and will submit to Infrastructure Australia a list of five key infrastructure projects which support the future infrastructure challenges and opportunities facing the Southern Downs.
The council resolved at the August general meeting to submit the following projects for consideration:
Pipeline diversion of water from the Clarence River in NSW to Tenterfield, Southern Downs, Western Downs and Toowoomba...... [my yellow highlighting]
The Chronicle, 3 September 2019, p.5, excerpt:
It comes as the council [Toowoomba Regional Council] starts confidential discussions around long-term water strategies, which could include new pipelines from northern New South Wales or even a new dam within the region.
Water and waste chair Cr Nancy Sommerfield said she had been in constant discussions with Water Resources Minister David Littleproud about a new pipeline from the Clarence River in NSW.
“The Clarence River is something I’m looking to talk about – there’s been a lot of work done on that, and I’m going to Canberra to speak with the minister soon,” she said.
“I really do like the idea of getting water from the Clarence, because it also solves issues for the Southern Downs.” [my yellow highlighting]

Let’s keep Kia Ora Dam a figment of imagination
It comes as no surprise that all four councils currently calling for the damming and diversion of water from the Clarence River system at Maryland River are themselves part of the Murray-Darling Basin group of councils.
It also comes as no surprise that three of these councils are in southern Queensland.
Just like Clarence Valley Council and its predecessors, these four councils have known for decades that they faced a future where diminishing regional water resources and increasing demand would make reliable water supply an issue for local governments.
However, unlike Clarence Valley Council and its local communities, these councils did not attempt to future proof their water supplies until it became a matter of urgency for their own communities.
One could almost feel sorry for them until one realises that at least one of the Queensland councils has started to explore new dam and pipeline options in its own backyard.
So why this push to dam and divert water from the Clarence River system? Well, it seems the best option in the Southern Downs region is considered way too expensive by the council there.
One has to suspect that some bright spark on this council decided that if all three Queensland councils joined forces and included a NSW council for good measure they could get Commonwealth and NSW state funding for a dam twice the size with minimum cost to their own coffers.
In 2017 Southern Downs Regional Council even published the name of this proposed 20,000-30,000 megalitre dam to be sited in the Upper Clarence catchment – it’s called the “Kia Ora” dam.
To date these wannabee water raiders have apparently not even undertaken an up-to-date desktop study on the feasibility of this dam and pipeline proposal.
Yet still they call for a dam which has the potential to reduce the Maryland River below the dam wall to a trickle even after it recovers from the present drought, and the potential to place the Upper Clarence water supply and environmental water flows at greater risk.
It is interesting to note the Environmental Impact Statement for the proposed Emu Swamp Dam in southern Queensland mentions previous consideration of “Kia Ora” by Sinclair Knight Merz:
“The Kia Ora dam site on the Maryland River in NSW has been investigated (SKM 1997b, 2007c) but it is not considered to be a viable option. A preliminary analysis suggests that, at full development, the site might be able to provide the required water supplies.
However, more detailed yield assessments for other dam sites in the area have shown that these preliminary assessments have all over-estimated the available yield. It is likely that further work would demonstrate that even the indicated yield is not available.
This site also carries risks arising from the reliability of information that was available to be used in the assessment; the unknown foundations; the high dam wall; the unknown side-spillway foundations; cross-border water transfers and delays and costs arising from the inability of the SSC to use its legislated powers (eg for compulsory land acquisition) in NSW.”
It seems these four councils are not facing the reality of their situation as well as failing to recognise that the Clarence Valley already shares water with a much larger regional population to the south of its own borders and cannot safely increase its water sharing arrangements.

For communities such as Tenterfield Shire, whose very survival is quite possibly on the brink without a long-term water plan, tapping into nearby available resources could be what is required to keep crops in the ground and families from moving away.
The difference between life and death.
For the Toowoomba, Western Downs and Southern Downs councils in the northeastern pocket of the failing Murray-Darling Basin, growing populations coupled with water scarcity is a worrying conundrum.
The headwaters of the Condamine River, which forms part of Australia’s longest river system with the Murray and Darling rivers, rise on Mt Superbus east of Warwick. Less than 50km away as the crow flies is the proposed Maryland Dam site on the Clarence River earmarked by the mayors of those four council areas as top priority in a list of projects to be presented to Infrastructure Australia.
But as one reader exclaimed when they told me they saw the plans on Southern Downs Regional Council’s Facebook page yesterday morning:
“You’ve got to be kidding me. It’s like going to the bank and saying ‘We’re going to rob your bank, watch out’.”
Any plan to divert water from one system to another leaves a deficit – environmental and economic – where it came from in the first place.

Pipe Dream
I have just read this article with great concern and I hope Mayor Simmons and CVC are not waiting for these other councils to get in touch with them before they do something about their proposal to divert our precious Clarence River.
No offence, but I think this decision is above your tier of government, so I would strongly advise that you take a more proactive stance on this issue.
We have seen already the damage done by misguided water allocations in the past, (think Murray-Darling as an obvious example), probably half the reason these electorates are running out of water.
As I’m sure you are aware, we are in the midst of a severe drought, so this apparently small percentage of fresh water that we take out of the Clarence catchment would in real terms be most of the water currently going in, leaving very little to actually continue on to the sea. What a lot of people fail to realise is the Clarence is tidal to above Grafton.
This excess fresh water, that we apparently have, mixes with salt water from the Pacific Ocean to form what is known as brackish water and is responsible for its own, very diverse, lifeforms. Ribbon grass, other plants, fish and a great deal of other lifeforms rely on this brackish water. It also carries sediment and nutrients vital to the bottom end of the river and the ocean to sustain life the whole way down.......
As a 55-year-old, third-generation born and bred Clarence Valley local, a surfer, fisherman and son of a professional fisherman, I have had a great love and association with the Clarence and the ocean and would hate to see it destroyed by narrow-minded bureaucrats.
It would be nice to think it will continue in its present form for my children and theirs.
