The Department of Agriculture and Water Resources publishes monthly the progress of environmental water recovery in relation to bridging the gap towards the proposed sustainable diversion limits (SDLs) in the Murray-Darling Basin Plan.
Current recoveries are as at 31 October 2017
‘Bridging the Gap’ Water Recoveries
The Murray-Darling Basin Plan sets out a local water recovery target for each SDL resource unit area. This target must be met by recovering water from within that SDL resource unit area in order to successfully ‘bridge the gap’. Commonwealth and State contracted water recovery against these targets are set out below.
Surface Water Recoveries
|Shared zone (all units in gigalitres)||Local target SDL reduction||Shared target SDL reduction||Total target SDL reduction||Total recovery progress||Total recovery remaining *|
Northern Basin zone total||
|NSW zone||590.0||458.0||1 048.0||774.7||273.3|
|Vic. zone||627.0||425.3||1 052.3||
Southern Basin zone total||
|Disconnected NSW (Lachlan)||48.0||N/A||48.0||
|Disconnected Vic. (Wimmera–Mallee)||23.0||N/A||23.0||
* This does not take into account the potential reduction to the water recovery target that may arise from the Northern Basin Review and the operation of the SDL Adjustment Mechanism. Allow for minor rounding.
The surface water recovery target was reduced by 70 GL from 2750 GL to 2680 GL as a result of Basin Plan amendments following the Northern Basin Review. These amendments were tabled in Parliament on 14 November 2017 and are disallowable for 15 sitting days. The sustainable diversion limit reduction amounts above do not currently reflect these amendments which took effect from 14 November 2017. If the amendment is not disallowed, the change will be reflected in the 30 November 2017 report.
For more information on Basin Plan amendments.
The Commonwealth is undertaking water recoveries that aim to protect the long-term productive base of the Queensland Upper Condamine Alluvium aquifer, consistent with the groundwater sustainable diversion limits set by the Murray–Darling Basin Plan.
|Shared zone (all units in gigalitres)||Local target SDL reduction||Shared target SDL reduction||Total target SDL reduction||Total recovery progress||Total recovery remaining|
|Upper Condamine Alluvium||40.4||N/A||40.4||
* Groundwater recovery does not contribute to the surface water recovery target of 2750 GL.

Efficiency measures water recoveries
As set out in the Basin Plan, the SDL Adjustment Mechanism adds flexibility to the SDLs by allowing equivalent environmental outcomes of the Basin Plan to be achieved through more efficient use of environmental water (Supply Measures) and further environmental outcomes to those agreed in the Basin Plan to be achieved while maintaining or improving social and economic outcomes (Efficiency Measures). Efficiency Measures projects will potentially recover water needed to meet the SDLs.

Notes for the above tables:
All water recoveries figures are expressed in long-term average annual yield (LTAAY) terms.
Surface water average annual yields are calculated using the current long-term diversion limit equivalent factors (v2.05) agreed to by Ministerial Council in November 2011 or are consistent with accredited Water Resource Plans. All Overland Flow water recoveries have their factors individually modelled by the Murray-Darling Basin Authority.
Water recovery is reported at the point at which water savings or purchase have been received, estimated or agreed in signed contracts. Until water transfer contracts have been exchanged however, these figures may be subject to change over time.
For total water recoveries allow for minor rounding.
