The proposed Warragamba Dam Raising Projects Environmental Impact Statement was on public exhibition from the 29th of September to the 19th of December 2021. You may still view the EIS document on the Department of Planning and Environment portal. WaterNSW is now reviewing the submissions received during the public exhibition and responding to the issues raised in a submissions report to the Department of Planning and Environment in 2022.

The project has been declared a Controlled Action under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 due to the likely impact on matters of national environmental significance including:

  • World Heritage properties (the Greater Blue Mountains World Heritage Area and National Heritage Place)
  • National Heritage places
  • Listed threatened species and communities.

The environmental assessment will be undertaken through the Bilateral Agreement between the NSW and Australian governments.

Field surveys

Surveys and assessments have been undertaken in accordance with the methodologies and guidelines required under the project SEARs.

Field surveys included:

  • Aboriginal cultural heritage surveys
  • Aquatic and terrestrial ecological surveys (flora / fauna species and communities)
  • Geomorphological surveys
  • Noise and vibration assessments in the vicinity of Warragamba Dam
  • Non-Aboriginal heritage investigations
  • Visual amenity and landscape character investigations
  • The outcomes of the field surveys will inform the environmental assessment.

Other relevant environmental issues, not requiring field surveys, will also be considered in the EIS as outlined in the projects SEARs.
