Progress of water recovery under the Restoring the Balance in the Murray-Darling Basin program
The Restoring the Balance in the Murray-Darling Basin program is a component of the Sustainable Rural Water Use and Infrastructure Program.
The aim of the Restoring the Balance in the Murray-Darling Basin (RtB) program is to provide more water for the environment, which can be used to protect and restore Basin river systems and wetlands. To date, the RtB program has secured the purchase of more than 4,500 individual trades.
The information in the table below has been updated to reflect the details of purchases secured through exchanged contracts recorded as at 30 June 2014. Further updates will be made as additional contracts are exchanged.
The table summarises the water purchases made through the Restoring the Balance in the Murray-Darling Basin program, including the purchase of Toorale Station (Barwon-Darling and Warrego catchment) water entitlements. Some points to note regarding this purchase information are:
- It is not possible to gauge the average annual volume of water that will be recovered in each catchment by just considering the entitlement volumes that have been purchased as the long term average water yield varies across both catchments and entitlement types. To account for these variations in yield, estimates are also provided of the annual volume of water that is expected to be available for environmental use, for each entitlement type in each catchment. These figures are calculated using the Department's estimates of long term average annual yield, as advised in the Murray-Darling Basin Ministers' Communiqué of 4 November 2011.
- Average price paid per trade is calculated over the life of the program. Information on average prices paid in the most recent tenders can be accessed on the Restoring the Balance in the Murray-Darling Basin page. The difference between the average price over the life of the program and prices paid in the most recent tenders is due to changes in market conditions while the program has been operating.

The data include some adjustments to previously reported information as a result of quality assurance checks on program data.
All figures in this table are calculated using the Department of the Environment estimates of the long term average annual yield (LTAAY) for each entitlement. It was advised in the Murray-Darling Basin Ministers' Communique of 4 November 2011 that these would be used to determine how much of the 'gap' between the Baseline Diversion Limit (BDL) and the Sustainable Diversion Limits (SDL) has been 'bridged'.
(1) This data includes unregulated water entitlements acquired from the NSW Government relating to its purchase of Toorale Station. Under the NSW Intersecting Streams Unregulated and Alluvial water sharing plan, an additional entitlement has been issued to the Commonwealth - an unregulated river special additional high flow entitlement. This is a new class of entitlement and requires advice regarding the LTAAY of this entitlement from the MDBA and NSW Government. The yield to this entitlement has not been included in the water recovery estimates presented in this table.
(2) Other Purchases include water purchased from the Wimmera and Murray Irrigation Irrigator Led Group Proposals, water acquired from the New South Wales Government relating to its purchase of Toorale Station and the water purchase from the Victorian Government relating to the Goulburn-Murray Water Connections Program.
(3) The average price paid per trade does not include water purchases from 'Other Purchase Initiatives - Average Annual Yield (ML)' and displays N/A where there are less than 5 trades.
(4) Condamine Balonne - the Commonwealth has purchased 10GL of overland flow entitlement which contributes to 'bridging the gap', but this recovery is not shown in the table because there is currently no long term diversion limit equivalent factor available to estimate the long term average annual yield (LTAAY) recovery volume for this entitlement.
