Water Allocation Plan for the River Murray Prescribed Watercourse

The new Water Allocation Plan for the River Murray Prescribed Watercourse was adopted on 3 October 2017 and announced by the Minister for Water and the River Murray, Ian Hunter in Murray Bridge on 13 October 2017.

The plan includes important information about the way we take and use water from the River Murray. To see the plan and find out what this means for you, please go to the NR SAMDB website 

After July 2018, authorisations will be reissued to reflect some of the changes in the plan. Until then, your current authorisations remain valid. For further information about your authorisations, call the Berri water licensing team on (08) 8595 2053, drop in for a visit at 2 Wade Street, Berri or email

Water Resources Update

South Australian water allocations are based on the water resource availability to South Australia. The Murray-Darling Basin Authority provides monthly updates on the water resources conditions across the Basin. The following Water Resources Update provides information on:

  • recent inflows to the Basin
  • volume of water in storage (Murray-Darling Basin Authority controlled)
  • Bureau of Meteorology’s three month weather outlook.

Historical Water Allocations

During the Millennium Drought, it was necessary to place restrictions on water allocations to share, conserve and manage the restricted volume of water available to South Australia. 

Water restrictions that have applied to South Australian Water Access Entitlement Holders in the past are summarised in a table showing monthly water allocations since July 2002.

What is a water announcement?

A water announcement is information that is reasonably likely to have a material effect on the price or value of a Murray-Darling Basin water access right. Water announcements are defined in section 12.49 of the Basin Plan 2012 water trading rules and include:

  • allocation announcements
  • private carryover  announcements
  • any other public announcement from the Minister that may have a material effect on the price or value of a water access right.

The South Australian Minister publishes water announcements in the South Australian Government Gazette and in a media release that is uploaded on the DEWNR website.
