Narrabeen Lagoon Projects

Narrabeen Lagoon is the largest of Warringah’s four coastal lagoons with a surface area of two square kilometres and a catchment of 55 square kilometres. The lagoon supports an important aquatic ecosystem and is used extensively by the community and visitors for a wide range of active and passive recreational activities, including boating, fishing and swimming. Several projects have been undertaken to assess and restore Narrabeen Lagoon and its catchment area.

Restoration Project

The Narrabeen Lagoon Restoration Project will see water depths restored to the equivalent of those that existed prior to catchment development through selective removal of material in the shallow areas and includes restoration of seagrass beds and native vegetation. More...

 

Creating a Sustainable Catchment Project

Narrabeen Lagoon was given a new lease of life in 2007 with a $1.9million grant. The grant will be spent over three years on a catchment-wide education program and on ground works such as creek bank remediation and bush regeneration. More...

 

Entrance Management

When the amount of sand that is moved into the lagoon entrance by the incoming tide continually exceeds the amount of sand removed by the outgoing tide, the entrance to Narrabeen Lagoon becomes filled with marine sediment. To reduce the risk of flooding, Warringah and Pittwater Councils undertake clearance operations. More...

Flood Study

Narrabeen Lagoon Flood Study is being reviewed. The new flood study will use new computer technology to accurately map flooding from the lagoon, creeks and tides. It will also address issues such as climate change and the effect development on the entrance conditions have on the flood levels. More...

 

Multi-use Trail Project

The Narrabeen Lake Multi-Use Trail aims to design and construct the final links of the existing trail network along the foreshores of Narrabeen Lagoon. The outcome will be an 8.5km trail circumnavigating the entire lake and providing improved access to the lagoon's foreshores. More...

 

Rehabilitation of Mullet and Nareen Creeks

Pittwater Council has adopted draft rehabilitation plans for Mullet and Nareen Creeks. The plans set out key actions to prevent further degradation of the two creeks which have been identified as having major problems with sedimentation build-up, pollution and weed infestation. More...

 

Estuary Management Plan and Study

Under the NSW Estuary Management Policy, local Councils are responsible for the preparation and implementation of management plans for estuaries in their jurisdiction. Warringah and Pittwater Councils developed the Narrabeen Lagoon Estuary Management Study, 2002 (PDF, 2MB) and Narrabeen Lagoon Estuary Management Plan, 2002 (PDF, 8MB).

The goal of the Management Plan is to achieve a balance between the environment and human influences within Narrabeen Lagoon. This will assist in maintaining and enhancing the ecological, aesthetic and recreational value of the lagoon and initiates community education on the link between the lagoon and its catchment.  

Crown Lands Assessment (Belrose, Cromer, Oxford Falls)

This assessment was undertaken by the Department of Lands in order to consider the future use and management of numerous parcels of Crown Land within Belrose, Cromer and Oxford Falls. More...
