It has just been announced that work is about to commence on the first project to improve water quality in Lake Tuggeranong. This will begin with the draining of Isabella Pond and Upper Stranger Pond to allow for the upgrade of the weir and the constructions of new wetlands. For the latest on this and the other projects planned to improve Lake Tuggeranong please come to our next TCC meeting on Tuesday the 4th April at the Vikings Southern Club.

JOINT MEDIA RELEASE
Work is set to start on a new project that will increase the public amenity of Isabella Pond, improve water quality in the Tuggeranong area and better prepare for rare flood events, Senator for the ACT Zed Seselja and Minister for Urban Renewal Mick Gentleman announced today.
The Isabella Pond wetlands project is the first to be constructed as part of ACT Healthy Waterways, 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.
Senator Seselja said the project would not only deliver recreational benefits to Canberrans, but would also contribute to a healthier Murray–Darling Basin.
“The Australian Government is committed to building better water infrastructure that delivers benefits for communities right across the country. In the ACT, we are contributing up to $76 million for the construction of key water infrastructure projects to improve long-term water quality and reduce levels of pollutants and nutrient runoff entering our waterways.
“These kinds of projects are a win–win. They create an even better environment and opportunities for recreation for Canberrans, and also deliver flow-on benefits for downstream water quality and river health for the Murray–Darling Basin.
“I look forward to seeing this project delivering real benefits for ACT communities soon,” said Senator Seselja.
“The area around Isabella Pond and Upper Stranger Pond will soon be fenced and the water drained so work can start on the construction of new wetlands,” Minister Gentleman said.
“They will attract birds and other native wildlife and play an important role in improving water quality downstream in Lake Tuggeranong, the Murrumbidgee River and the wider Murray-Darling Basin.
“While Isabella pond is drained to construct the wetlands, the ACT Government will also undertake an upgrade of Isabella Weir to bring it into line with national best practice guidelines and the recently introduced ACT Dam Safety Code.”
The draining of the ponds also allows for the removal of carp, a pest species, and the later restocking of the ponds with native fish.
“This is a great opportunity for the ACT Government to restore a more natural environment in the ponds and improve water quality by building wetlands, removing the carp and restocking with native fish,” Minister Gentleman said.
“Fauna and flora that live in and around the ponds will be carefully managed during the project.”
Construction will affect the residents of Tuggeranong in several ways, including minor disruption to off-peak traffic along Drakeford Drive bridge during site establishment and the closure of both ponds for the length of the project. Detours for walkers and cyclists will be in place and clearly signposted.
Upper Stranger Pond will be allowed to refill once the carp have been removed but Isabella Pond will remain empty for 12-18 months to complete the weir upgrade and the construction of the wetlands.
Tuggeranong Pond, downstream of Isabella Pond, will also need to be lowered during construction of the weir. Tuggeranong Pond will not be emptied, but the level will be lowered by between one and two metres.
