Assessing environmental water needs of the Basin

The Water Act 2007 requires that assessment of environmental water needs of the Basin must encompass key environmental assets, including water-dependent ecosystems, ecosystem services, and sites with ecological significance; key ecosystem functions; the productive base; and key environmental outcomes for the water resource.

The purpose of this document is to:

  • outline the approach that the MDBA is taking to determining the scale of change required
  • present a list of 18 indicator key environmental assets which are being used to inform the development of the Sustainable Diversion Limits (SDLs)
  • present detailed results for 3 of the 18 indicator sites: the Barmah–Millewa Forest, Macquarie Marshes, and the Riverland–Chowilla Floodplain.
