What area does the plan cover?

The NSW Murray-Darling Basin Porous Rock Water Resource Plan covers groundwater located within the sedimentary basins in the NSW portion of the Murray-Darling Basin as well as alluvial sediments that overlie these sediments that have not been explicitly captured elsewhere.

The NSW Murray Darling Basin Porous Rock (GW6) is composed of four sustainable diversion limit resource units (SDL resource units):

  • Gunnedah-Oxley Basin MDB (GS17)
  • Oaklands Basin (GS38)
  • Sydney Basin MDB (GS41)
  • Western Porous Rock (GS50)
