Lake Burley Griffin is central to the unique landscape and design of the Nation’s Capital. The rough stone lake walls iconic to the Lake are over 56 years old, and now need remediation in order to extend their useful life.
“$3 million of construction and repair works have commenced on the Lake walls, a much-needed injection for the Canberra economy as we begin to recover from the impacts of COVID-19,” said Senator for the ACT, Zed Seselja.
“Works were recently underway at Acton Peninsula, are currently here at Lennox Gardens today, and will been seen across other sites on the Lake over the next 18 months.”
“Lake Burley Griffin is a central part of Canberra life. People of all walks of life are drawn to the Lake – whether for some exercise, as part of a visit to our great National Institutions, or for a family picnic,” Senator Seselja said.
“These works are just one of many investments in Canberra in recent times by the Liberal-National Government.”
“Last week we saw an $8 million injection for infrastructure funding, and we have recently committed $100 million to the Monaro Highway, $500 million for an expansion of the Australian War Memorial, and more than $63 million for the National Gallery, amongst other significant investments in Canberra.”
Since the start of the filling of the lake in 1963, wind and wave attrition have weakened mortar joints between rocks that has led to the loss of soil from behind the lake shoreline walls. In some cases, stones have dislodged, and paving has become loose on the top of walls. The lake walls are believed to have been constructed in the two years prior to the lake being filled, making the walls approximately 56 years old.
Innovative processes such as ground penetrating radar and resin injection are being used to improve wall stability to enable another 50 years of serviceable life.
The National Capital Authority (NCA) is the agency responsible for managing the lake wall remediation program. The NCA’s role extends to the ongoing maintenance and management of Lake Burley Griffin and associated infrastructure. The role also includes ensuring that built assets such as the lake walls, jetties, beaches, the Captain Cook Memorial Jet, Aspen Island (including the National Carillon) and Scrivener Dam are all maintained in a safe and serviceable condition for all to enjoy.
