On 10 June 2015, the Murray–Darling Basin Authority (MDBA) announced that trading water from above the Barmah Choke to below the choke will continue to be restricted into the 2015-16 water year.
As explained in the MDBA's media release this will mean that on 1 July 2015 no allocation will be able to be traded from upstream to downstream of the Choke until there has been equivalent trade in the opposite direction.
Trading through the Choke
If you plan to trade water through the Choke, you or your broker need to keep an eye on any trading limits that apply to you.
