Testing of the lake bed at West Basin will begin next week as part of preliminary work to realign the shoreline for Stage 2 of the waterfront development, a key step in connecting the city centre to Lake Burley Griffin.
The City Renewal Authority said the National Capital Authority had approved geotechnical investigations to determine the depth of the sediment on the lake bed, which will assist with the foundation design required to construct the proposed 500 metres of boardwalk and new lake wall.
It said Stage 2, which is due to begin in early 2019, would also reclaim 2.8 hectares of the lake bed to provide for a generous waterfront urban park.
The testing, which did not require drilling and would not disturb the lake bed, would take place from a barge in the lake over the next few weeks.

The results will be used in the design plans to be included in the works approval application to the NCA for Stage 2, which will realign the West Basin shoreline so it is consistent with the National Capital Plan.
City Renewal Authority chief executive Malcolm Snow said this would be lodged once negotiations with the Federal Government on the transfer of part of the lake bed to the ACT Government had been resolved.
“The redevelopment of West Basin into a more people-friendly area is a key objective for the City Renewal Authority,” Mr Snow said. “That’s why our priority is the creation of high-quality public spaces as the first stage of redevelopment.
“Opening Henry Rolland Park has already transformed a bleak car park into a wonderful new public space for people to visit, spend time and connect with their community.
“Stages two and three will complete the boardwalk and promenade at West Basin and will include a new urban park, play areas, public facilities and opportunities for cafes and restaurants.
“The Griffins envisioned the city centre connected to the lake and the creation of these contemporary public spaces in West Basin will be a critical step in realising that link.”
West Basin is Designated Land and works approval from the NCA is required for all development work, with all applications subject to public consultation.
