The Commonwealth Water Holder has announced that they will be selling annual water allocations to the entitlements that they hold in the Gwydir Valley.
As discussed on this blog (Nov 2012 and Nov 2013) and elsewhere (a conference paper at AARES 2012, and a journal article about to be published) this is a reasonable move. There has been plenty of water in those parts of the country in the last few years, there have been good floods, and ecosystems are up and running. Sitting on the environmental water cannot do much good, so selling some annual allocations makes perfect sense.
Of course, this has to be done in a careful and prudent way, with constant monitoring of the situation on the ground. If done properly, it will be a good thing for the irrigators and their communities, without causing harm to the environment.
