Water allocations and announcements

Minimum water allocations in 2020-21 for South Australian Class 3 (High Security) and Class 8 entitlement holders are now - as of 3 August 2020 - at 81 per cent. This has risen from 77 per cent previously announced on 15 July.

A range of advice has, and continues to be, provided to water users. This information provides greater support for business planning, as we understand that this is especially important when water allocations are less than 100 percent.

The next update for water users will be on Monday 17 August 2020.

Also, if you missed the previous South Australian Government business support webinars for irrigators over the last few months, you can catch up on the April session and May session with our catch up videos.

South Australia’s River Murray Water Allocation Statement – updated 3 August 2020

South Australia’s River Murray Water Allocation Statement  for 3 August 2020 has been prepared to provide South Australian River Murray entitlement holders with the latest information about water availability and resources.

This latest statement provides updated information on allocations, private carryover, water held in Murray-Darling Basin Authority controlled storages, climate outlook and projections for irrigation water allocations under a range of scenarios.

While there has been some rainfall across the Basin over the last few weeks, it has not been enough to significantly improve water availability to South Australia. Since the 15 July 2020 announcement, South Australia’s minimum River Murray Entitlement has increased by 30 gigalitres (GL) to 1,370 GL. 

The updated projections indicate that even if the exceptionally dry scenario plays out over the next six months, South Australian Class 3 (High Security) allocations are likely to reach 100 percent by November 2020.

Private carryover is available for eligible water users in the 2020-21 water year. The existing 100 percent limit on the combined allocation and carryover volumes granted under Class 3 (High Security) entitlements continue to apply in 2020-21.

Now that allocations have reached 81 percent, some water users may have reached their 100 percent limit to be taken in 2020-21.  Any part of an allocation increase that would take a water user above 100 percent will go into a rollover account.  For example, for a water user who carried over 20 percent of the volume of their Class 3 (High Security) entitlements, all allocation improvements above 80 percent from this announcement will now go into their rollover account.

The Bureau of Meteorology’s three month outlook indicates further rainfall is likely. Most inflows to the River Murray system historically occur between July and November. This should provide water users with a degree of confidence that we will see further improvements to South Australia’s water availability for 2020-21.

The publication of River Murray Water Allocation Statements is part of the South Australian Government's commitment to giving greater support and more timely information to River Murray water users to help them in their forward planning.

While water allocations remain below 100 percent, we will provide fortnightly statements with the latest water allocations and resources information.

The next update will be provided on Monday 17 August 2020.
