As part of the Environmental Impact Statement (EIS) for the Lake Lyell Pumped Hydro Project, a detailed Biodiversity Impact Assessment has been completed.

This scientific study assesses how the project could affect local plants, animals, and ecosystems, and identifies ways to avoid, reduce or offset those impacts.

Key Findings from the Biodiversity Assessment:

Over two years, biodiversity experts and ecologists have surveyed the project area — mapping vegetation, identifying habitats, and monitoring species.

We’ve integrated a number of measures into the project design to reduce environmental impacts from the outset, including:

  • Using existing infrastructure where possible and refining the project footprint
  • Avoiding construction close to sensitive areas, like Marrangaroo National Park
  • Creating a lake diversion to maintain water connectivity for fish and platypus between Lake Lyell and Farmers Creek
  • Installing silt curtains to manage sediment, and implementing speed limits, fencing, and lighting controls to protect wildlife
