The Project

The Burdekin Falls Dam Raising Project is a proposal to raise the existing dam as a potential means to increase water supply in the Burdekin and surrounding regions.

What’s involved?

Sunwater is working with the Queensland Government who is leading a detailed business case (DBC) to further investigate raising the dam. Works may include raising of the spillway, abutments and saddle dams, as well as adjustments to the spillway apron and possible changes to the access road alignment.

As part of the project, an Environmental Impact Statement (EIS) must be undertaken to assess:

  • the current environment around the project
  • potential environmental, economic and social impacts and benefits of the project
  • the proposals being put forward to avoid, minimise, mitigate and/or offset potential impacts.

For more information, visit the EIS process.

The Queensland Government approved the development of a detailed business case in September 2019.

Future water demand assessment

NCEconomics, in partnership with Synergies Economic Consulting, have been engaged by the Queensland Government to undertake an assessment of long-term water demand in the Burdekin region. Their work will evaluate the current water use and potential water demand growth patterns over the next 30 years.

This is a critical task underpinning the dam raising project’s DBC and will inform the potential height of the dam wall raising.

Sunwater and the Queensland Government invited growers to outline their current water use and future intentions via a survey as part of the Burdekin demand assessment.

The survey closed on Friday, 30 October 2020. Results from the survey and feedback from face-to-face consultation is being analysed. The assessment will report on aggregated data only.
