Active management

Active management rules protect environmental water from extraction in the unregulated Barwon-Darling, Gwydir and Macquarie-Bogan water sources.

What are the active management rules?

The active management rules were implemented in December 2020 to protect active environmental water (AEW) from extraction in the unregulated Barwon-Darling, Gwydir and Macquarie-Bogan water sources. AEW includes:

  • held environmental water (HEW) flowing from an upstream water source
  • planned environment water (PEW) from upstream water sources protected from extraction under the existing water sharing plan rules (e.g. active sub-allowance from the Macquarie Cudgegong regulated river)
  • licensed unregulated river water where the licence holder has notified the Minister that they want the water left in the unregulated river water source and protected from extraction

Before the rules were implemented, AEW could have been legally extracted from these water sources, so that it might not reach intended targets. Active management also gives licence holders and other stakeholders more certainty about how flows are managed and makes it clear when water can and cannot be taken.
