Works to better understand the depth profile and characteristics of silt build-up will soon be undertaken across Lake Apex and Lake Freeman, Lockyer Valley Regional Council has announced.
Council’s Environment Portfolio Councillor Michael Hagan said the Council had commissioned the survey works to commence shortly.
“Council has engaged Range Environmental, together with specialist surveyor MinStaff Survey to undertake a bathymetric survey from 16-17 January, weather permitting,” said Mr Hagan.
“Bathymetric surveys measure the depth of and map the underwater features of a water body.
“This information will be used to assist Council in our ongoing planning and assessment of desilting opportunities for the lakes system.
“During these works, access to the lakes by kayak and remote-controlled survey craft will be undertaken by specialist contractors.
“Residents and visitors may notice watercraft and operators within and around the lakes system during this time, and we appreciate the patience and understanding of all residents while these works are undertaken,” he said.
Cr Hagan moved to assure residents the safety of wildlife would remain of the highest importance throughout the two-day period.
“Disturbance of wildlife and breeding habitats will be minimised by contractors during survey works.”
“The bathymetric survey works follow the completion of preliminary fish and bird surveys, completed last year.
“The fish survey identified there was no known species of any significance within the lakes themselves, with the dominant species found including Goldfish, Eastern Mosquito Fish, Firetail Gudgeon and Spangled Perch.
“Council is now moving to better understand the amount of silt and the water volume that remains in the lakes.
“Further works, including underwater soil sampling are scheduled to be completed in February 2024.
“From here, Council will finalise the suggested approval strategy and management plan to undertake any silting works.
“These investigations are in response to the community feedback received to ensure the lakes remain a quality community asset that supports and protects its unique fauna habitat, balanced with its role as a vibrant cultural precinct for residents and visitors to exercise, play and explore,” he said.
