This Strategy aims to minimise adverse effects on the ecology of the area, minimise build-up of sand in the lake entrance, and reduce impacts of flooding, while providing residents and visitors with opportunities for recreational activities.

Periodic dredging of the lower estuary is undertaken to ensure that recreational amenity is maintained within the waterway, with the dredge spoil being used to nourish nearby areas subject to erosion.

Council undertakes water quality monitoring at Lake Cathie to ensure that the system is healthy and is acceptable for recreational purposes (i.e. swimming, fishing).

Council has undertaken a detailed modelling study to investigate the benefit of potential management options or improvement works identified for the Lake Cathie Estuary.

The Lake Cathie CZMP will guide the management of the Lake Cathie foreshore into the future to ensure the most beneficial outcome for local residents, the community and the environment.
