Transitional SDL water take reports

The Basin Plan introduced a new water accounting and compliance framework based on sustainable diversion limits that began on 1 July 2019. For the period 2012 to 2019, the Murray–Darling Basin Authority (MDBA) and the Basin states have been trialling the methods underpinning the compliance and sustainable diversion limits to ensure a smooth transition occurs between Cap reporting and sustainable diversion limit (SDL) reporting.

The Transition Period Water Take Report 2018–19 reports the consumptive take of water from the Murray–Darling Basin under both the Cap compliance reporting and the trial sustainable diversion limit accounts. It also reports on environmental water held, available and used in 2018–19.

It is important to note for the 2018–19 water year Cap compliance is the only Basin scale compliance framework. The transition sustainable diversion limit water accounting and compliance are a proof of concept during 2018–19 and have no compliance consequences. They are a benchmark against which the MDBA has monitored and will continue to improve sustainable diversion limit water accounting and reporting.

The trial sustainable diversion limit water accounts set out in the 2018–19 report have been prepared using the best available information from draft or accredited water resource plans where possible, for example revised accounting adjustments for environmental water. This approach has been retrospectively applied over the period 2012–2019. These retrospective changes will produce a number of differences compared to the 2017–18 report, which are explained in the 2018–19 report.

From 1 July 2019, the sustainable diversion limit water accounting and compliance arrangements are enforceable. The MDBA has published the first set of formal sustainable diversion limit accounts for 2019–20.

State narrative reports

When Basin states submit their transitional sustainable diversion limit water accounting data to the MDBA each year, they also provide narrative reports setting out the particular water availability and reporting conditions experienced in that state in the relevant year. There may be differences between the volumes in the state narrative reports and those in the transitional sustainable diversion limit accounts. Such differences are likely the result of the significant change from Cap to sustainable diversion limit water take accounting and the extensive collaboration between the MDBA and each Basin state to ensure the transitional sustainable diversion limit accounts are prepared consistent with the Basin Plan.

Annual diversions from the River Murray and its tributaries
Annual diversions from the River Murray and its tributaries

The MDBA has published the water diverted from the River Murray and its tributaries. This information is also published in the Transition Period Water Take Reports and Cap Compliance Reports, but here the information is presented at a smaller scale and by specific purpose. The tributaries include the Kiewa, Ovens, Goulburn, Broken, Loddon and Campaspe in Victoria and the Murrumbidgee in New South Wales. Where data is available, the diversion data is also split by river sections and/or irrigation districts. The specific uses include water taken by private diverters and for urban, stock and domestic and industrial uses. It covers the years from 1997–98 to 2018–19.

Of particular note:

  • The annual diversion data includes interstate and across valley trade. For example, where water is traded from New South Wales to South Australia, the diversions are reported in South Australia.
  • The annual diversion data excludes losses due to conveyance along the river to the point of offtake, but for irrigation areas, it includes conveyance losses from the point of river offtake to run in supply channels.

Surface and groundwater trial water accounts on one page

The information presented in the Transition Period Water Take Reports draws on transitional water take accounts for surface water and groundwater that have been prepared in a way that is consistent with the sustainable diversion limit water accounting and compliance framework. These accounts are set out over several pages at Appendix 1 and 2 of the reports. For easier viewing of these accounts on screen, these have been made available as separate, single page documents.
