- water shortage environmental impacts in the Millenium Drought were caused (mostly) by lack of run-off -the natural impact of drought-not by "over allocation".(Not to mention the Lower Lakes fiasco of not allowing sea water to enter).
- the very wet years that followed did much natural recuperative work and following the drought are a classic example of the natural variability of the basin, which is its central characteristic.
- The Government (CEWH) bought entitlements -"phantom water"-not real water. This remains phantom water until such time as there are allocations. By way of example the current Macquarie and Lachlan issues appear to mainly relate to lack of allocations.
- the Darling catchment (as distinct from the Murray) is again suffering extreme drought particularly in run-off terms.
- the massive variability of our run-off largely dictates water availability, particularly in the Darling catchment and our storages, whilst very beneficial, really only "fiddle at the edges".
- Richard Kingsford will say anything to support his anti-irrigation stance.
- given the massive variability, setting single figure SDL's, even if they are averages, is nonsense.
- the Murray Darling Basin Plan is an academic, impracticable "dog's breakfast" which will do huge damage to productive capacity and "bugger all" for the environment.

Four days of very considerable discomfort and largely sleepless nights followed. Thank God for family and friends visits and cricket and tennis TV diversions and a very amusing email exchange with my retired gynecologist friend in the wee hours one particular night. I emerged from hospital on a very wet day, five days after the operation. At home our low level bed and the lack of a hook above, made getting in and out of bed very difficult. I finally got a proper nights sleep seven days after the surgery, and that was heaven. I felt so well that yesterday I decided to join my usual lunch group at my city club. I will spare you the detail, but last night the bowel really rebelled and I am taking it very easy today. Have an appointment with my surgeon for next Thursday to have the 16 staples removed. Hopefully, there will be no need for any further "organ recitals"!

It was a fascinating experience and whilst I remain no expert, I am gaining a better understanding of the scheme itself from an engineering perspective and how Snowy Hydro manage it in accordance with the requirements of their shareholders and the agreements which govern the management. I must say I come away with great admiration of both. The Scheme is a master piece of engineering and I was most impressed with the management and general efficiency of Snowy Hydro. That is not to say that I don't still harbor views that the management of the scheme has lost sight of its original prime objective of water conservation for irrigation. I do, but that is not the fault of Snowy Hydro.
Snowy Hydro shareholders are the Governments of NSW, Victoria and Australia. It makes its money from hydro electricity generation, not irrigation water and these shareholders require it to maximise its earnings which, it seems to me, it does very well. Amongst many other things, the agreements which govern its operations require it to make minimum releases of a little over 1,000GL per annum to both the Murray and Murrumbidgee Rivers. Interestingly about half of this water once flowed east to the sea. In my view it could do considerably more in the water conservation area, but that would be in conflict with its shareholder's requirements.
Much of this relates to the timing of releases and among other things, the need to keep airspace in Blowering Reservoir so that water can be released when the demand for peak load electricity is strong.
The tour had a nostalgic aspect for me. When I was a school boy at Canberra Grammar I spent many holidays with the Miners family at Adaminaby. They held some Kiandra snow leases and I had several trips on horse back with pack horses taking livestock to and from the high snow country. One of the leases was Happy Jack's and I spent some nights camped at the Happy Jack's hut. I was thus delighted to see when we received the itinerary for the tour that the first stop after Jindabyne
Happy Jack's Dam. The scenery above
At the time of my school boy visits the Snowy Scheme was under construction and I well remember the houses being moved from the old Adaminaby to the new town site, before the old town area was flooded by Eucumbene Dam.
Suffice to say it was a thoroughly enjoyable and informative trip.

The Harvard Business Review recently ran an interview with Robert B. Shapiro, chairman and CEO of Monsanto, on the subject of sustainability.
Sustainable development is the term for the dual imperative—economic growth and environmental sustainability—that has been gaining ground among business leaders since the 1992 United Nations Earth Summit in Rio de Janeiro.
As Shapiro puts it, “We can’t expect the rest of the world to abandon their economic aspirations just so we can continue to enjoy clean air and water. That is neither ethically correct nor likely to be permitted by the billions of people in the developing world who expect the quality of their lives to improve.”
The interview with HBR editor-at-large Joan Magretta, discusses how Monsanto has moved from a decade of progress in pollution prevention and clean-up to spotting opportunities for revenue growth in environmentally sustainable new products and technologies.
HBR: Why is sustainability becoming an important component of your strategic thinking?
Robert B. Shapiro: Today there are about 5.8 billion people in the world. About 1.5 billion of them live in conditions of abject poverty—a subsistence life that simply can’t be romanticized as some form of simpler, preindustrial lifestyle.
As many as 800 million people are so severely malnourished that they can neither work nor participate in family life. That’s where we are today. And, as far as I know, no demographer questions that the world population will just about double by sometime around 2030.
Without radical change, the kind of world implied by those numbers is unthinkable. It’s a world of mass migrations and environmental degradation on an unimaginable scale. At best, it means the preservation of a few islands of privilege and prosperity in a sea of misery and violence.
Far from being a soft issue grounded in emotion or ethics, sustainable development involves cold, rational business logic.
Current agricultural practice isn’t sustainable: we’ve lost something on the order of 15% of our topsoil over the last 20 years or so, irrigation is increasing the salinity of soil, and the petrochemicals we rely on aren’t renewable.
Most arable land is already under cultivation. Attempts to open new farmland are causing severe ecological damage. So in the best case, we have the same amount of land to work with and twice as many people to feed. It comes down to resource productivity. You have to get twice the yield from every acre of land just to maintain current levels of poverty and malnutrition.
Now, even if you wanted to do it in an unsustainable way, no technology today would let you double productivity. With current best practices applied to all the acreage in the world, you’d get about a third of the way toward feeding the whole population.
The conclusion is that new technology is the only alternative to one of two disasters: not feeding people—letting the Malthusian process work its magic on the population—or ecological catastrophe.
We don’t have 100 years to figure that out; at best, we have decades. In that time frame, I know of only two viable candidates: biotechnology and information technology. I’m treating them as though they’re separate, but biotechnology is really a subset of information technology because it is about DNA-encoded information.
How does biotechnology replace stuff with information in agriculture?
Shapiro: We can genetically code a plant, for example, to repel or destroy harmful insects. That means we don’t have to spray the plant with pesticides—with stuff. Up to 90% of what’s sprayed on crops today is wasted. Most of it ends up on the soil.
If we put the right information in the plant, we waste less stuff and increase productivity. With biotechnology, we can accomplish that. It’s not that chemicals are inherently bad. But they are less efficient than biology because you have to manufacture and distribute and apply them.
I offer a prediction: the early twenty-first century is going to see a struggle between information technology and biotechnology on the one hand and environmental degradation on the other.
Information technology is going to be our most powerful tool. It will let us miniaturize things, avoid waste, and produce more value without producing and processing more stuff. The substitution of information for stuff is essential to sustainability.
B.t. Cotton. In ordinary soil, microbes known as B.t. microbes occur naturally and produce a special protein that, although toxic to certain pests, are harmless to other insects, wildlife, and people. If the destructive cotton budworm, for example, eats B.t. bacteria, it will die.
With products like B.t. cotton, farmers avoid having to buy and apply insecticides. And the environment is spared chemicals that are persistent in the soil or that run off into the groundwater.
The Roundup molecule has smart features that contribute to sustainability. It is degraded by soil microbes into natural products such as nitrogen, carbon dioxide, and water. It is nontoxic to animals because its mode of action is specific to plants. Once sprayed, it sticks to soil particles; it doesn’t move into the ground-water. Like a smart tool, it seeks out its work.
How do you react to the prospect of the world population doubling over the next few decades? First you may say, Great, 5 billion more customers. That is what economic development is all about.
That’s part of it. Now, keep going. Think about all the physical implications of serving that many new customers. And ask yourself the hard question, How exactly are we going to do that and still live here? That’s what sustainability is about.
