EIS public exhibition has ended

From 25 September to 6 November 2024, the NSW Department of Planning, Housing and Infrastructure placed Council's Environmental Impact Statement (EIS) on raising Clarrie Hall Dam on public exhibition through the NSW Planning Portal.

Thank you to everyone who made a submission.

The public exhibition was an important milestone in our journey towards securing all necessary NSW and Australian Government approvals to raise Clarrie Hall Dam by 8.5 metres.

A response-to-submissions report will now be prepared and the department will consider this before making a recommendation to the Minister for Planning and Public Spaces, who will determine whether our proposal to raise the dam can go ahead and what conditions would apply.

If the Minister determines the project can proceed, the elected Council would consider consultant recommendations and the Minister’s determination, and decide to proceed or not to proceed. If Council decides to proceed, business case planning for detailed design and construction would be undertaken, and approvals and licences for construction finalised.



Advice about the EIS

We developed the following resources to assist people in making a submission.

View the EIS

Head to the Clarrie Hall Dam Raising project page on the NSW Planning Portal.

You will find the EIS covers expert studies commissioned by Council into the impact of raising the dam wall by 8.5 metres on such issues as:

  • dam safety
  • cultural heritage
  • biodiversity
  • flooding
  • water quality
  • hydrology.

It also reviews the impact of constructing the higher dam wall on traffic, noise and air quality.

To support you with understanding the EIS, we have developed an information summary.

Community information sessions

In October 2024, we ran information sessions face to face and online. Thank you to everyone who attended.

  • Kingscliff Bowls Club - 23 October
  • Murwillumbah CWA Hall - 24 October
  • Uki Holy Trinity Church - 24 October
  • Online daytime - 25 October
  • Online evening - 28 October



Role of community feedback

The Department of Planning, Housing and Infrastructure welcomes your feedback on the EIS and the wider dam-raising proposal as it helps the NSW Government understand the views of the community.

This in turn, helps the Government inform its assessment of the project leading to improved design, reduced environmental impact and ecologically sustainable development.

This feedback is being collected by the department through a public exhibition. The exhibition process allows any individual or organisation to have their say about the proposed infrastructure.


The NSW Government has partly funded the EIS through the Safe and Secure Water Program.
