[3] Heavy rains in June 2007 caused Tuggerah Lake to flood, affecting areas of Long Jetty, Killarney Vale and Chittaway Point.

Much of the original settlement bordering the lake was oriented towards domestic tourism; with Sydney residents drawn to the area and staying in camp and early cabin-style accommodation clustered around towns of The Entrance and Long Jetty, from there spreading to Toukley on the northern lakeshore.

Tuggerah Lake is well known for its recreational fishing with species such as luderick, bream, flathead and whiting caught from the shoreline and boats.

Substantial residential and commercial development, involving excavation and alteration of native vegetation and natural watercourses in the lake catchment and hinterland, has given rise to siltation and changes in the make up of the lakebed and foreshore.

Restoration work has focussed on inshore removal of weed and ooze; foreshore reclamation and reinstatement; pollutant traps; and channel dredging to increase the tidal exchange of water with the sea.

Wyrrabalong National Park borders the lake and the sea separating the residential areas of Toukley and The Entrance, and preserves the last significant littoral rainforest on the Central Coast.
