Canaipa Passage dredging program provides 2.5m depth between Moreton Bay and Gold Coast

The Gold Coast Waterways Authority (GCWA) has invested $500,000 in maintaining safe navigational access in the Canaipa Passage, the important link between Moreton Bay and the Gold Coast.

The dredging aims to provide a depth of -2.5m LAT (Lowest Astronomical Tide) in the channel. This project was finished ahead of schedule and under budget due to favourable weather conditions and GCWA’s streamlined project delivery processes.

GCWA Acting CEO Jessica Bourner said the Authority has committed over $15 million to dredging projects across the next four years to make sure navigation channels and destinations remain safe and accessible for all waterways users.

“As a waterways city, these works are vital to ensure we’re sustainably managing Gold Coast waterways for everyone who uses them,” said Ms Bourner. “Our Program ensures that the waterways are well planned and maintained so that those who use and enjoy them can do so safely and responsibly. It’s also about making sure that they remain an important asset for current and future residents, visitors and businesses to enjoy.

“Over the coming years, more dredging will be carried out in the Coomera River, at Jacobs Well, Jumpinpin, Main Channel, Nerang River, North Channel, South Channel, South Wavebreak Island and West Crab Island.” said Ms Bourner.

The Canaipa Passage project focussed on maintaining safe navigable depths and replenishing the foreshore at Slipping Sands and is an important part of GCWA’s Waterways Management Program.

Located in the Moreton Bay Marine Park, the project was carried out in line with the Sand Management Plan for Gold Coast waterways and the stringent conditions set out in the environmental approvals.
