    Grafton floodwaters would save Murray-Darling—build the Clarence Scheme!
    Once again, the Clarence River is in flood at Grafton, NSW, but if the Clarence River Scheme—which has been on the books since at least the early 1920s—had been built, that water would now be on its way down the Darling River, to save the parched towns, farms and lakes of South Australia.
    The scheme would divert the waters of the upper Clarence and Nymboida Rivers over the Great Dividing Range into the Dumaresq River, and on into the Macintyre, Barwon, and Darling Rivers, before flowing into the Murray River near Mildura, and on down to South Australia. Additionally, a nearby Macleay River project would divert water into the Gwydir River and on into the Barwon and Darling Rivers.
    Emeritus Professor Lance Endersbee designed the Clarence Scheme as a pump storage scheme, which can take advantage of surplus off-peak electricity to pump water over the range and into storage dams, which will then produce hydroelectricity from an annual flow of water comparable to that of the Snowy Mountains diversion.
    (Professor Endersbee was Dean of Engineering and Pro-Vice Chancellor of Monash University, at the end of a long career which included distinguished work on the Snowy Mountains Scheme, Tasmania’s hydro scheme, and hydroelectric schemes in Southeast Asia.)
    He told a conference in 1997, “There is the catchment of the Clarence River and it is a wonderful little cup in there, and very steep country, high rainfall and one of the highest rainfall areas in Australia, and they get the summer rains down from the monsoons coming down and they get the winter rains as well.
    “So there is a lot of rainfall there and it all flows out into the sea, and if you have been to Grafton, you know how wide the Clarence River is at Grafton. It’s a big river.
    “So I have ... designed a scheme for the diversion of the Clarence into the Darling. Now ... there is a lot of algae in the Darling... This would flush all the algae out of the Darling.”
    Most importantly, the Clarence River diversion would go a long way to saving the Murray-Darling Basin, Australia’s food bowl, which produces 40 per cent of the national agricultural output, and comprises 75 per cent of Australia’s irrigated land.

    Would have to take a lot of care with that one as if you take to much fresh from that river you will have salt a lot further up the river and would not do a lot for the eco system, the water in the river at Grafton township is subject to tides but is mostly fresh .
    I just want to snowboard.

    I think this guys intentions are to build a dam to catch rain water and keep the sea water on the other side of that dam, obviously with a spillway to stop Grafton from being flooded, I have no idea about the area, it was just a copy and paste of something I read.
    It does seem a pity to waste all that flood water when the Murray at Albury has nearly stopped flowing and Lake Hume was a little over 2% a few weeks ago it is now just over 5%, and it's capacity is many times that of Sydney harbour.

    Just a thought, tell me why they take so much water out of the Shoalhaven river system pump it to Warragamba dam but that dam seems to fall in level? Is it because they pump it strait out to sea so when the new water filtration plant is up and running at kernell they will justify the money thay have spent?
    if your in deep go deeper!

    it is always annoying to see all the flood water just flow out to sea, it there was a way to turn it inland that wasnt prohibitivly expensive then great. pumping all that water over the ranges would take huge amounts of power.

    RE: the clarence scheme - the only trouble is, taking water from one river system to "help" another ends up damaging both. it may seem wasteful, but australia's rivers are designed to be both extreme's and it's necessary for ecological function to be maintained.

    bandaid approaches haven't worked in the past, and they will continue to fail. Looking at the causes is essential - upstream uses of water etc.

    Look at what has happened to the snowy river downstream of jindabyne? It's a shadow of it'self and although some flow was officially returned, it's still not a shadow of itself, which is killing the river system and riparian areas and necessitating hundreds of thousands of $$$ to be spent on managing it for weeds, erosion, planting native species etc etc etc. It's all interconnected

    The Murray / Darling is not far behind it.

    Selfishly, I'd hate to see the Nymboida ruined... There are some great rapids to ride!

    For this to work there are some seriously high mountains to pump water over (or tunnel through) - anywhere between 1400- ~1700 metres high.

    I think the idea is to tunnel under - exactly what the snowyhydro system does. if the dams on the east side are built high enough, then you can turn the water around with gravity feeding, and driving hydro power plants. again how snowyhydro works.

    it depends on the geography though, and i don't know the area very well.

    the notion that we can put water from one are to another area and "save" it is ludicrous and shows a european way of thinking. What kind of life do people want? one where there are healthy systems which can support healthy produce and healthy human communities? or a life where everything is dying because we've changed it and man handled it for our own selfish purposes?

    There's a reason the murray is ****ed and the darling - inappropriate crops in unsuitable environments.

    Everything's already been said. Incorrect crops, incorrect farming practices, all sorts of thing. None of which really can be attributed to the farmers, they were just doing what the GOVERNMENT told them to do at the time... Worlds best practice and all that sort of stuff but you find out later it was wrong. Willows are a classic example.
