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). 1 Table A - Details of measures Measure Proponent Geographic Type of Details of the measure Surface water SDL Relevant constraint Notification Date the location measure resource units measures amendment measure affected by the approval entered or will measure enter operation 1 Chowilla SA, NSW Chowilla Creek Supply This measure identifies This project is not BOC 48 30/06/2024 The Chowilla Floodplain works is part of a program of Floodplain and Victoria all southern connected reliant on constraint 18/05/2017 The Living Murray (TLM) works at icon sites along the TLM Project basin SDL resource measures for River Murray to ensure that environmental water units as affected units implementation or recovered as part of TLM is used efficiently and for the purposes of operation. ecological elements are maintained.

Through the construction of three large regulators, a series of smaller supporting regulators, track raising (levees) and a pipeline (to allow use of temporary pumps) this project will connect extensive areas of floodplain through tiered watering events. These works will make use of natural flow paths to increase the extent, frequency and duration of inundation from either MDBP flows or pumping during low flow events. 7 Burra Creek Victoria The Burra Creek Supply The proposed works will enable inundation of an area of This measure identifies Not directly linked to BOC 48 30/06/2024 Floodplain floodplain is 407 ha.
