Register of Measures The Murray–Darling Basin Authority (MDBA) has the responsibility for maintaining a register of supply and efficiency measures agreed by Basin governments to be considered in the Sustainable Diversion Limit (SDL) adjustment mechanism. This register must be published on the MDBA website. The register of measures reflects: • the formal notification of the package of measures to the Authority by the Basin Officials Committee (BOC) • all efficiency measures added to the notified package of measures until 31 December 2023 • updates to entitlements as they are acquired under the efficiency program until 31 December 2023 • all amendments to notifications up to 31 December 2023. Because of the interdependent nature of measures, an estimate of the likely supply contribution: • is calculated at an overall package level, rather than for each separate notified measure • is available subject to the completion of modelling of SDL adjustment measures • is provided through apportioning across surface water SDL resource units. The register is provided in the form of two tables: • Table A lists the relevant details of each notified measure (this Table is current at 4 May 2018) • Table B lists the efficiency entitlements and likely SDL adjustment for each of the Basin’s surface water SDL resource units (this table is current at 31 March 2019).

Notes 1 SDL resource units with a column shown as '‐' contribute a zero volume. 2 efficiency entitlements – sum of face value of held environmental water entitlements transferred to Commonwealth Environmental Water Holder for efficiency measures. This does not include efficiency measures that are contracted and the entitlement is yet to be transferred. Efficiency measures are the notified measures that formed the initial adjustment proposed by the MDBA in 2017. Refer to Table A. 3 additional efficiency entitlements – sum of face value of held environmental water entitlements transferred to Commonwealth Environmental Water Holder for additional efficiency measures notified after the 2017 adjustment, as per s7.12(2) Basin Plan. This does not include additional efficiency measures that are contracted and the entitlement is yet to be transferred.

4 long‐term annual average volume of efficiency entitlements ‐ volumes as per s6A.02 (1) Basin Plan Schedule 6A. This is the long term annual average and not the face value of efficiency entitlements. This volume increases when an efficiency measure results in a transfer of an entitlement that is registered as held environmental water and is owned by the Commonwealth Environmental Water Holder. Face value of efficiency entitlements are converted using the agreed long‐term diversion limit equivalent factors (LTDLE factors), v2.05 dated November 2011 agreed to by Ministerial Council or are consistent with accredited water resource plans. 5 long‐term annual average volume of additional efficiency entitlements ‐ volumes as per s6A.02 (1) Basin Plan Schedule 6A. This is the long term annual average and not the face value of efficiency entitlements. This volume increases when an efficiency measure results in a transfer of an entitlement that is registered as held environmental water and is owned by the Commonwealth Environmental Water Holder. Face value of efficiency entitlements are converted using the agreed long‐term diversion limit equivalent factors (LTDLE factors), v2.05 dated November 2011 agreed to by Ministerial Council or are consistent with accredited water resource plans. 6 apportioned supply contribution ‐ volumes as per s6A.02 (2) Basin Plan Schedule 6A.

7 reduced supply contribution ‐ The Basin Plan limits the net adjustment for supply and efficiency measures to SDLs to 5% of the Basin‐wide SDL, or 543 GL/y. Until efficiency measures results in entitlements being transferred to CEWH have at least a long term annual average volume of 62 GL/y, the full effect of the apportioned supply contribution (605 GL/y) is reduced and SDLs remain limited. The apportioned supply contribution is reduced proportionately across all surface water SDL resources with a supply contribution (Basin Plan Schedule 6A s6A.05(3)).

8 SDL adjustment amount ‐ is the combination of achieved long term annual average volume of efficiency entitlements and the reduced supply contribution. Overall, this volume has a maximum adjustment of +/‐ 543 GL/y. The SDL adjustment amount is currently added to the BDL and deductions are made for the local reduction amount and the shared reduction amount to determine the likely SDL (as set out in Basin Plan Schedule 2). The MDBA's web site provides more details about BDL (Table 1) and SDLs (Table 2) at https://www.mdba.gov.au/basin‐plan‐roll‐out/sustainable‐ diversion‐limits under More information.
