Bird Lake Project

Update – November 2019

Following the commencement of the Bird Lake Project early in 2019, Cu River Mining Australia purchased the adjacent former power station site from which soil needs to be excavated for the project.

Following the change of site ownership in May 2019, Port Augusta City Council, the South Australian Government and Cu River Mining have been working closely to reach agreement on access to the site for soil material needed for the project.

To ensure that native plants can germinate and grow, works for the project will commence in March 2020 after the passing of the hot, dry and windy time of year.

Bird Lake current state

Bird Lake in Port Augusta is being rehabilitated with local native plants in selected areas to reduce the potential for odour issues and improve the area.

The project is being delivered by the Port Augusta Council with the cooperation of land owners and funding support from the South Australian Government.

Why does Bird Lake smell?

Bird Lake is a part of the Augusta Lakes salt-lake system. In its natural state the lake is not full of water and historically foul odours and biting insects were a problem from time to time.

The odour coming from Bird Lake is mainly caused by decaying mats of algae around the lake edge. The algae grew while the lake was kept full from water that overflowed from an Ash Disposal Area when the Northern Power Station was in operation. When the Power Station closed and the lake dried out, the algal mats were exposed and started to decay. How strong the odour is, is dependent on the wetting and drying of the algal mats.

How is it being rehabilitated?

Bird Lake is being rehabilitated by covering areas of decaying algal mat around the fringes of the lake with soil and seeding this soil with low growing local native plants that are tolerant of the highly saline and arid conditions. “Capping” the algal mats this way will reduce the potential for odour from the lake. Rubbish scattered around the lake and the old cloth screens adjacent the highway will also either be removed or buried under the capping soil.

The works will take place from March to July 2019 following community, landholder and stakeholder engagement. Follow up seeding may be undertaken in Spring 2019 or Autumn 2020 if appropriate.
