There have been significant changes in the lake since the June 07 flood:
There are new sandbars , the channel to the ocean is now much wider allowing more water to move in and out of the lake with the tides.  At low tide it's quite difficult to get to the Long Jetty boat ramp in anything other than a very small boat.

Tuggerah Lake
Due to the lack of tidal movement at the central area of the lake, the most productive areas of Tuggerah Lake are the inlets at Chittaway Point where Ourimbah Creek waters enter and the mouth of Wyong River at Tacoma. They produce bream, mullet, luderick and flathead, especially after a heavy rain. To the north, Canton Beach is a good producer of whiting, bream and flathead for the land based angler.

The Entrance
The channel where the Tuggerah Lake system meets the Pacific Ocean is known as The Entrance. Fish from the banks of the mouth for luderick and the odd bream. The channel is also known for its prawn runs. As it is fast flowing, prawning is usually done when the tide is slack or turning, two to three days either side of a new moon. East of The Entrance bridge is a top spot drifting for bream, flathead and whiting. Anglers drifting live baits to the west of Pelican Island stand a chance of landing large flathead that lie in wait for their prey on the edge of the channel. North Entrance beach is a good spot for whiting and tailor during their runs.
