Wilcannia Weir Replacement

Wilcannia Weir Replacement

About the project

WaterNSW is designing and constructing a new weir for Wilcannia on behalf of the State and Federal Governments under the Sustainable Rural Water Use and Infrastructure program.  $30 million in funding has been provided under the program to replace the weir at a site that was supported and agreed upon by the community during previous investigations and consultation by DPI, Water.

The Wilcannia Weir was constructed in 1942 for the purpose of providing a more reliable town water supply for Wilcannia. Water levels have decreased as a result of development activities since the weir was built, causing the river to be altered and removed from the community of Wilcannia.

The new weir will provide long-term town water supplies to preserve and enhance the social, economic and environmental benefits for Wilcannia, its people and its surrounds.

A dedicated WaterNSW project team has been assembled to undertake the concept design and environmental assessment for the new weir so the project can progress to the detailed design and construction phase by 2020.


The new weir will have a range of benefits including:

  • Improved water security for Wilcannia
  • Enhanced cultural connection to the river
  • Improved water management of the weir pool
  • Increased tourism opportunities and investment
  • Better recreational amenity to walk, swim, picnic and fish
  • Improved native fish migration

Community consultation

WaterNSW understands the importance of the river to the community and want to design and construct a weir that meets community needs and expectations and maintains the strong connection people have to the river.

Community drop in sessions, to share information and get feedback on the design are being held at key milestones throughout the project. Regular updates to the community via newsletter, factsheets, newspaper and radio are to be made available.

Community engagement

Project schedule

Due to the restrictions in place for the outbreak of COVID-19 and an updated planning approval process, there are changes to the time frame for the Wilcannia Weir Replacement project. The Weir project is continuing and WaterNSW is preparing an Environmental Impact Statement which will require in depth environmental and cultural heritage assessments and community consultation.

WaterNSW is committed to continued engagement with the Wilcannia community. The project team will communicate via phone, email, video meetings, advertisements, local radio and news. Project updates and flyers are providing information and we will continue to work closely with the community and with a project reference group.

The estimated timeline for the project is as follows:

  • State and Federal Government joint funding announcement - November 2018
  • Completion of Final Business Case by Department of Planning Industry and Environment - June 2019
  • WaterNSW engaged to design the new Weir - September 2019
  • Environmental Planning Approval – April 2020 to May 2021
  • Capital Project plan endorsement to commence construction activities - July 2021
  • Commence Early Works  – September 2021
  • Construction starts – October 2021
  • Construction complete - February 2022

Project updates

A Baaka Adventure with Gillie

To further support community engagement and awareness of the weir replacement project, a children’s activity booklet A Baaka Adventure with Gillie was developed.
