Isabella Pond Precinct Improvement Works

The Isabella Pond precinct will undergo significant work during 2017 and 2018. Three separate improvement projects are now underway for the waterways and Isabella Pond.

The projects are:

  • Construction of the Isabella Wetlands as part of the ACT Healthy Waterways Project.
  • Widening of Isabella Weir.  
  • A carp management project in Upper Stranger and Isabella Ponds.

All three projects require both Isabella Pond and Upper Stranger Pond to be drained. To minimise impacts on residents and pond users, and only drain the ponds once, the works will happen simultaneously.

Isabella Pond Wetlands Project

The new wetlands will attract birds and other native wildlife and provide more opportunities for recreation and play. They will also play an important role in improving water quality downstream in Lake Tuggeranong, the Murrumbidgee River and the wider Murray-Darling Basin.

The Isabella Wetlands project are part of the  ACT Healthy Waterways Project, a joint initiative of the Australian and ACT governments to invest more than $80 million in the construction of water-quality infrastructure on up to 25 sites across the ACT.

Isabella Weir Upgrade

The ACT Government is funding an upgrade of Isabella Weir to bring it into line with national best practice guidelines and the recently introduced ACT Dam Safety Code.

Carp Management Program

Carp are an introduced freshwater fish and listed as a pest species.

Draining Isabella Pond and Upper Stranger Pond presents an opportunity for the ACT Government to remove the carp and, once the project is complete, restock with native fish. This will restore a more natural environment in the ponds and improve water quality.

Eradicating the carp also allows ecologists to conduct valuable research ahead of the National Carp Control Plan (funded by the Australian Government) which may involve the release of a biocontrol, the carp herpes virus, over the next two to three years.

How these projects will impact you

  • Upper Stranger Pond will be allowed to refill when carp have been removed, but Isabella Pond will remain empty for approximately 12-18 months to complete the weir and wetland construction.
  • Trucks will pass in and out of the area during the improvement work. Routes have been established to minimise traffic disruption and noise.
  • Detours for walkers and cyclists will be in place and will be clearly signposted. Both ponds will be fenced for public safety during the entire length of the project.
  • The contractor has prepared a Construction Environment Management Plan (CEMP) to detail how it will deal with the flora and fauna issues.
