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 17 November 2017).
