Macquarie-Castlereagh Regional Water Strategy

The following frequently asked questions relate specifically to the Macquarie-Castlereagh Regional Water Strategy.

Is the Macquarie re-regulating weir a done deal?

No. The NSW Government has committed to developing a business case to explore the option of constructing a new, re-regulating gated weir and fishway structure on the Macquarie River. The preferred option will also undergo further assessment with an Environmental Impact Statement (EIS) involving technical, hydrological, environmental, biodiversity, cultural and economic feasibility studies, and further stakeholder consultation.

Visit WaterNSW for more information on the project.

What are the impacts of the Narromine–Nyngan pipeline project in the lower Macquarie?

WaterNSW is undertaking two related drought security studies in the Macquarie–Castlereagh region. These are the:

  • Drought Relief Strategy, which is developing drought relief solutions for the townships of Macquarie Valley that will avoid towns failure in current and future droughts
  • Nyngan and Cobar Drought Security project, which is considering the development of infrastructure to ensure that Nyngan and Cobar do not run out of water during the current drought.

WaterNSW is consulting with councils on these two projects and no decisions have been made on the preferred option or options at this stage.

What is happening with the water entitlements from Wallerawang power station?

The water needs of communities and industry in the upper Macquarie (unregulated) system are undergoing significant change with the growth of cities like Orange and Bathurst, changed water management from mine operations and the closure of the Wallerawang power station, which is associated with a large water entitlement.

The Draft Macquarie Regional Water Strategy includes an option to conduct a Regional Towns Water study to identify options to improve water security for towns that rely on water from the upper Macquarie (unregulated) system, which include Bathurst, Orange, Oberon, Lithgow and Sydney Water between Katoomba and Mt Victoria. The study would take a strategic approach establishing the current and future needs of water users in the system and holistically examine the range of options to improve water security for the towns.
