Lake Gillawarna was previously suffering with typical symptoms of an urban catchment including; decreased water quality, excessive weed and algal growth, loss of native fauna habitat, increased levels of sediment, increased banks erosion as well as the presence of pest species such as carp that predate on native fauna and destabilise the banks. 

The project has delivered:

  • 13,000 native plants;​
  • 1,500 square metres of garden beds with sandstone mulch;
  • 2,000 square metres  of aquatic wetland area;
  • 70 metres of formal lake edging;
  • 630 metres of informal lake edge treatment; and 
  • The removal of large and annual weeds from around the lake and the island.

These changes will allow for the water quality of the pond to increase by reducing the sediment levels, improving circulation reducing the impacts of excessive nutrients as well as improving the dissolved oxygen levels by circulating water over shallow wetland areas.
