Default Aquaducts - irrigating Australia

Has there been a serious study done to see the feasibility of channeling
water from our far north to some of the drier parts of our continent? I'm
thinking of a massive pipe and aquaduct system.

It does seem sad that some parts of our land suffer from too much water -
whilst other parts suffer from its lack.

I'm not thinking that such a mammoth scheme could be achieved in 10 or
even 100 years- but what's the alternative? Desalination plants don't
seem to be that effective.

It would require cooperation from Federal, State and local - but if
achieved- it would be a boon for future generations.



P A Yeomans wrote several books (Water for every farm, Keyline Plan and
City Farm) on using water that is diverted from run off. As most of the
rivers in the north flood then are dry a week later it is a waste of a
water resource as it heads out to sea.

Farmers could utilise trapping water on their farms and having several
water storages. Then they could irrigate when needed. This is providing
they are on loam based soil with adequate slope.

Unfortunately now I think the government has decided to charge for dams
and storage of water. Citing that they are stopping flows to the rivers.
Unfortunately this has good points and bad. By not having dam storage the
water runs off into the rivers. By having storages you reduce the runoff
but once the dams are full run off proceeds as nature intended. So we need
to look at the long term benefits not a governments term in office.

Agriculture is a big user of water. So reducing it's impact by requiring
farmers to have adequate storages on their land is a better option. This
of course is providing they have the right conditions to do so.


Saw a flood warning for the Balonne river yesterday so maybe "Cubby" will
get a bit of inflow and manage it's first cotton crop in 3 or 5 years. No I
am not stirring but it is damn wet out here. Where I live (not far from
Dirrin) we have an average annual rainfall of 500mm. Last year we had 590
odd, 300 in Nov/Dec, previous year 300mm for the year. This year 53mm so far
in 7 days.
Can't do any gardening because everything is waterlogged, waded through 2
inches of water to read the rain gauge this morning.
Well at least the cockies are smiling, not the wives though.

P.S. Bradfield scheme, about the 20/30s I believe proposed the diversion of
coastal water to the inland.
