What's happening in October

  • The Social Impact Assessment (SIA) survey is now open. Have your say before October 30 on the potential impacts and benefits of the project. Click here to take the survey.
  • Environmental investigations are continuing this month with further cultural heritage studies and biodiversity surveys to monitor flora and fauna in the local area.
  • Surveys to start which will assess bushfire risks and how to manage them.


WaterNSW has released a 20-year infrastructure options study for rural river valleys which addresses future challenges in operating regulated river systems. The objective of the study was to guide water infrastructure investment by all levels of government.

Prime Minister Scott Morrison and NSW Premier Gladys Berejiklian have announced a jointly funded package of around $1bn for the planning and delivery of three new or augmented dams in NSW. This includes $24m for a Final Business Case for building a new dam on Mole River, in the Border Rivers region of NSW.

The Border Rivers is a large catchment that services both NSW and QLD users. Its water supply is serviced by three relatively small catchment dams and large on-farm storages. A new dam will have the potential to secure more water in flood sequences so that in drier times more water would be available to communities, agriculture, and the environment.

Key benefits

  • Enables sustained on-farm productivity as a result of more reliable and secure water supply
  • Increased reliability for agricultural production will help secure existing jobs and create new opportunities
  • Will improve security of town water supply and provide flood mitigation
  • Potential benefits for the downstream Barwon-Darling system through increased flow reliability and associated environmental health outcomes
  • Benefits are shared between QLD and NSW

Social impact assessment

WaterNSW is seeking approval from the NSW Minister for Planning and Public Spaces and the Commonwealth Minister for the Environment to construct the Mole River Dam project.

The assessment process requires that WaterNSW prepare a Social Impact Assessment to accompany the Strategic Business Case for the project to address the potential social impacts and benefits of the project to the local area, the region, and the state of NSW.

You can be involved in the SIA through an online survey (Closing date: Friday 30 October 2020).
