Water security

Ensuring ongoing access to a reliable water supply is a priority for the NSW Government and a core focus of the $4.2 billion Snowy Hydro Legacy Fund.

To support farmers and regional communities by ensuring ongoing water security, the NSW Government is investing in dams, pipelines and weirs in priority catchments across regional NSW. 

The Snowy Hydro Legacy Fund drives some important water security projects which are led by the Department of Planning Industry and Environment (DPIE) Water Division.

Regional Water Strategies

The Regional Water Strategies assess potential drought and flood impacts using climate data and water modelling to deliver long-term policy, planning and infrastructure solutions, to ensure ongoing water security and resilience across regional NSW.

There are a total of 12 Regional Water Strategies, with the following already released:

  • Border Rivers – on public exhibition until 30 November 2020
  • South Coast and Far North Coast Rivers – on public exhibition until 13 December 2020
  • Macquarie-Castlereagh, Lachlan and Gwydir Rivers – public exhibition closed 13 November 2020

Priority Dam projects

Together with the Commonwealth Government, the NSW Government will deliver critical water security infrastructure to support regional communities and economies. They are:

  • Delivering the Wyangala Dam wall raising to provide water security and flood mitigation for towns and industries in the Lachlan Valley;
  • Delivering a new Dungowan Dam and pipeline to build a new 22GL dam, to improve water security in the Peel Valley; and
  • Investigating the Mole River Dam to improve water to communities, agriculture and the environment in the Border Rivers region.

Infrastructure projects

There are four infrastructure projects underway to improve long-term access to water for communities and industries in regional NSW. Investigations are currently taking place for: 

  • Macquarie River weir that will increase water storage and reduce water lost to evaporation in the Macquarie Valley;
  • Lake Rowlands to Carcoar Dam pipeline to increase water supply by transferring water from Lake Rowlands Dam to Carcoar Dam;
  • Hunter Water Corporation to Singleton interconnection to replenish water supplies in the Upper Hunter from the lower Hunter; and
  • Lostock to Glennies Dam pipeline to transfer water, providing water security for power generation, agriculture and mining.
