A Basin Plan That Works For All

By Ron Pike

Background: The incursion of the Federal Government into the State’s constitutional right to the management of rivers and their water; was the result of sensationalist and mostly false claims made during the millennium drought. Emotional sophistry replaced truth and reason as it was claimed that our rivers were dying as the result of extraction by irrigators and lack of flow in the Murray was the cause of hyper salinity in the Coorong. Claims of dying river red gums, drying wetlands and species loss were repeated with graphic but mostly misleading detail.

The Result: Is a Plan that that is costing Governments both revenue and credibility as regional communities across the whole MDB are regressing. The businesses that grow, process and transport our food and fibre are being destroyed by the removal of the vital input of water and the Government inspired racket called the water market. Incredibly, the Plan is badly impacting the environment it is supposed to be assisting and genuine environmental issues are not being addressed. Empty Dams, dry Rivers, communities without drinking water and dead aquatic fauna is the result.


This Plan acknowledges and highlights that there are environmental problems in the MDB that need to and can be corrected. Practical implementation of this “Plan for All” will not only provide superior environmental outcomes; it will result in healthier waterways and more productive regional communities. It will restore both the Coorong and Lower Lakes to healthy estuarine habitat for more desirable aquatic species. It will be the basis of an expanded fishing industry while maintaining recreational facilities. It will for the first time guarantee all water users in South Australia an abundant supply of fresh water at competitive prices.

This Plan provides for all the increasing water needs across the whole Basin and for the first time in decades all citizens of our great Food Bowl can be confident of a productive future. It will provide water for increased irrigated crop production in the Basin States and guarantee more fresh water for South Australia.

The Coorong: The declining health of the Coorong is widely documented and has been a recurring feature since the drought of 1860 when mist aquatic life died. It is a problem that has nothing to do with the flow, or lack of flow in the Murray River. However it is a problem that is worth permanently correcting and easy to do so. Redirection of feeder creeks into the southern lagoon, coupled with high tide ocean inflow would be a permanent cure for the Coorong’s ills. Large pipes under the sand dunes in several places would allow large volumes of sea water to flow into the Coorong between mid and high tide. Free swinging flaps on the outlet would automatically close as the tide dropped. Gravity would propel this water towards the so-called Murray mouth flushing hyper salinity out to sea. This would ensure that when creek inflow was negligible in drought times, the incursion of sea water would maintain a healthy Coorong.

Lake Albert: There is rightly concern about increasing salinity in Lake Albert, aggravated by its very shallow depth. No amount of extra flow from the Murray River will correct this problem. But it can be permanently overcome in a similar manner with one much larger pipe from the sea. The high tide inflow would flush through Lake Albert into Lake Alexandrina and out to sea, combining with the Coorong flow to increase outflow to the ocean, maintaining a healthy channel without dredging and more importantly without wasting large volumes of productive water as the present Plan does.

The Lower Lakes: This previous estuarine environment was changed to a fresh water regime by the building of barrages 75 years ago. While this was done for the then worthy reason of providing fresh water for both municipal and agricultural use, it is now causing unacceptable harm to the whole Basin and all other water users. It is the barrages that are the ongoing cause of lack of flow through the so called Murray mouth. The ineffective use of vast quantities of fresh water to correct this problem is the biggest mistake and greatest waste of water by the present Plan. CSIRO research indicates evaporation rates from the Lower Lakes are in the order of 1,171 to 1,445 mm per annum. That is an annual amount of around 1,000,000 MLs. Therefore the maintenance of this fresh water domain is costing Basin communities over Two Billion Dollars of economic activity just from evaporation.

The most flagrant untruth justifying the present Plan was the claim that the building of dams and the development of irrigated agriculture has resulted in less floods. That is less river flow events that put water over the river bank and as a result filling the numerous Billabongs and low lying areas with water, triggering an aquatic species breeding event. Flood records of the Goulbourn, Murray, Murrumbidgee and Lachlan Rivers for over 150 years prove this to be false.

The facts are we have had more over the bank events since we built the dams than we had in recorded history before. The reason is very simple and while rainfall records show a slight increase over MDB catchments, it is the development of irrigated cropping and as a result increased population and municipal development that has increased run-off into all of our streams.


Based on these Facts:

1. Recognition that most of the claims made to justify the Federal Government’s involvement in water and river management, manifested in the MDB Plan were false and in fact unconstitutional.

2. Appreciation that management of the water resources of the MDB over decades prior to the introduction of the MDB Plan were in the best interests of the Nation, mankind and were beneficial not prejudicial to the environment.

3. Acceptance that we cannot keep growing our population and economy without building more dams to store available water in times of plenty. Man has yet to develop a better way of providing for future water needs than dam building.

4. That releasing water above that required to maintain all of stream flow and extraction requirements, has no environmental return. It is flagrantly wasting a resource we can productively use elsewhere.

5. Water is our most abundant renewable resource and there are numerous sites to build further storage on most of our rivers and creeks. These storages all become pristine habitat for aquatic species and recreational facilities for mankind.

6. There are environmental problems in the MDB which do need attention and these are:

a) Eradication of European Carp.

b) Correction of hyper salinity in the Coorong.

c) Return of Lower Lakes to an estuarine environment while maintaining Lake water levels.

d) Providing all of stream flow for all major rivers, especially the Darling and its tributaries.

7. The introduction of Sustainable Diversion Limits (SDL’s) was never practical or workable because they are incompatible with the highly variable available water volume.

8. Licenses to use water for irrigation should only be held by entities which control irrigable land. These licenses should only ever be traded to similar entities within the valley in which they were issued.

9. River red gums are flood tolerant and not flood dependant and any artificial watering is also flagrant waste of a productive resource and much more likely to do harm rather than good.


1. Rescind the existing MDB Plan to be replaced with a strengthened multi State agreement which presently guarantees South Australia 1,850,000 ML (except in exceptional circumstances), increasing this guarantee to at least 2,000,000 ML per year.

2. Sell all water licenses presently held by the Commonwealth Environmental Water Holder and speculators to those who have land to irrigate within the MDB.

3. Use the income from these sales to correct the Coorong problems as detailed above and to return the Lower Lakes to an estuarine environment.

4. Set up the “Australian Infrastructure Fund;” specifically to build income earning infrastructure such as dams, hydro power plants and transport facilities. Money from the resale of irrigation licenses and money earmarked for the MDB Plan would be the seed capital for the Fund.

5. Immediately commence the building of more water storage facilities across the Basin; specifically assessing these as a priority:

A. The Lake Coolah- Stony Point off stream storage in the Murrumbidgee Valley.

B. The upper Clarence – Gwydir diversion. (1,200,000 ML P.A to the Darling system)

C. Building a number of weirs on the Darling River.

D. Diversion of high flows in the Kiewa River into Hume Dam, or dam on the Kiewa.

E. Increasing the capacity of Lake Buffalo.

F. Several storages on the Lachlan and its tributaries.

G. Reassess the Chowilla Dam as a permanent guarantee of SA’s water supply. Practical management of this resource will never be complete until Chowilla is built.

H. A dam on the Billabong Creek.

I. Numerous other sites have been assessed and could over time be built.

6. Implement research into permanent control of European Carp. Environmentally there is no more important objective.

This Plan would very quickly return growth to the communities of the MDB and as a result increase employment.

Rather than the present Plan’s ongoing cost to the Government, this Plan would increase Government receipts.

It would correct the real environmental problems within the Basin without wasting fresh water as is happening with the ineffective present failed Plan.

Aquatic species and mankind would both have enhanced environments as a result.

This Plan would stop wasting water and use water in the National interest to the long lasting benefit of man and the environment we share with other species.

  1. Ron,
    Not sure if you are aware but there are fresh water ‘reservoirs’ floating on the salt water table under the sand hills of the Coorong. Trenching to place a pipe under the these sand hills may have a detrimental effect on the fresh water soaks that wildlife & humans use along the Coorong. Sounds simple & a good idea but may have far reaching repercussions!

    1. Aert, I am continuing to fight for visionary but practical policy that will deliver to the resourceful, productive Australian people abundant cheap Water, Power and Gas. With fuel, these are the “Tools of Trade” for all production. Jobs for our Kids and maintenance of our standard of living are dependant on successfully doing this.

  2. Sounds like you just to look after your own patch and neglect others. Selling all CEWH holdings for example to irrigators will just land up in the hands of the few big companies trading water, they will further manipulate prices to the detriment of agriculture. Stupid.

    1. No D. Cole, what you describe is the present situation, only made possible by breaking the nexus between water and land that can be irrigated. We have quickly gone from having our stored water available for end users and producers in dry times to a situation where nearly all of our stored water is owned by speculators and green bureaucracies.

      The result is that even now when we are barely into what may become a serious drought we are out of water and by next year Australia will be importing food. This has already begun with several commodities. The MDB Plan is by any reasonable assessment, a crime against the people, and must as a starting point to practical management of our most abundant renewable resource, be repealed.
