Macquarie-Castlereagh Alluvium Water Resource Plan

Commonwealth accreditation - submitted

The Macquarie-Castlereagh Alluvium Water Resource Plan (WRP) has now been submitted to the Murray–Darling Basin Authority (MDBA) to assess the plan against accreditation requirements of the Basin Plan 2012. A copy of the submitted Plan and the schedules and appendices is available on the MDBA website. Changes made to the draft plan based on feedback from public exhibition and the MDBA’s preliminary advice is summarised in the outcomes of public exhibition fact sheet.

Water sharing plans continue to be the legal instrument for managing water resources in NSW. Water resource plans are put in place to implement the Commonwealth Basin Plan 2012.

What area does the plan cover?

The Macquarie-Castlereagh Alluvium WRP covers groundwater within the alluvial deposits of the Macquarie–Castlereagh catchment in central-western NSW.

The Macquarie-Castlereagh Alluvium (GW12) is composed of the following seven sustainable diversion limit resource units (SDL resource units):

  • Bell Valley alluvium (GS11)
  • Castlereagh alluvium (GS14)
  • Coolaburragundy–Talbragar alluvium (GS15)
  • Cudgegong alluvium (GS16)
  • Lower Macquarie alluvium (GS26)
  • Upper Macquarie alluvium (GS45)

Groundwater within the Great Artesian Basin is not included in the Murray–Darling Basin water sources as the Commonwealth Water Act 2007 excludes it.
