Narrabeen Lagoon ready for summer fun!

A significant project to remove the build-up of tens of thousands of cubic metres of sand from Narrabeen Lagoon is now complete and the lagoon is being reopened in time for the summer holiday period. 

The three-month sand excavation project is part of the ongoing management of the lagoon to help reduce flooding risk and is conducted every three to four years.

The work was done by amphibious excavators, pumping the excess sand through flexible pipes to a central stockpile location next to Birdwood carpark. From there the sand was transported to Mactier Street to replenish Collaroy-Narrabeen Beach.

The last significant sand removal was completed in 2018 and since then sand has gradually returned to the entrance through wave and swell action, eventually filling the entrance and causing the lagoon to regularly close.

Equipment is being progressively removed from the site and the lagoon entrance is being reopened today.

The sand clearance project has been run concurrently with the Ocean Street Bridge abutment repairs. The bridge repairs will be put on hold and we’ll recommence following the summer holidays to allow for better access during this busy time.  

In the meantime fingers crossed for some sunshine so we can all make the most of the lagoon over summer.
