We have a Murray-Darling basin plan but is it a plan for the future? : Comments
By Diane Bell, published 21/3/2013The plan fails to address in a scientifically rigorous manner the critical issues raised over and over again by scientists, Indigenous peoples, and community groups.

We did have an opportunity to fix the thing from the mountains down to the sea, irrespective of state borders or so called state's rights. We have already created a precedent and used external powers, to prevent a state from misusing an important waterway, when we took on Tassie and its intended plan for the Franklin.
We made a mistake in allowing over allocated water to become private tradable property.
No such property right ought to exist.
The end result, too many dams in all the wrong places.
We need many more dams in our high country, to force trillions of tons of record flood water into the landscape, from where it is not subject to evaporation outcomes, and is allowed to slowly leach back into our waterways, during those dry periods, where there is little or no rain.
All on farm storage ought to be covered and all irrigation applied via underground tapes.
This would allow doubled production for half the water use; or, normal production for quarter!
Strategically placed weirs, could be closed from time to time, to flood the red gums. Reopening them, in electronically controlled sequence, could send a wall of water right down to the Coorong and the river mouth, to routinely flush both out?
The river is one of the most engineered waterways in the world! It is patently not possible to unengineer it, just do it over and get it right.
Open channels that lose 60-70% of their flow to evaporation and leaking, must all be replaced with pipes.
Many of the traditional crops, like say, water hungry rice, need to be replaced with far less thirsty crops, like say, oil rich algae, which in closed cycle production, use just 2-3% of traditional irrigation, and will happily thrive on recycled water; which it cleans, before returning it to other use.
All our rice should be grown in the north, where our annual rainfall can be measured in metres!
