Tuggerah Lakes Flood Study - Compendium Of Data

Tuggerah Lakes is a water body on the NSW Central Coast comprising the three inter-connected lakes of Tuggerah, Budgewoi and Munmorah. The lakes are open to the Tasman Sea by a narrow channel at The Entrance (Figure 1).

There is considerable demand for land along the foreshores of the lakes largely because of the scenic and recreational value. A large proportion of foreshore land is flood liable. An improved knowledge of local flood behaviour is therefore desirable to enable Council to better manage future development.

This compendium contains an overview of existing reports from 1971 to 1992

Conclusion

It is concluded that historical Datum descriptions used within the Tuggerah Lakes area can be unreliable, particularly when used to compare historical flood levels.

It is recommended that all flood level data be reliably related to AHD using as an origin of levels:

  • Bench Marks (and Conversion Factors) given in the attached Table C2
  • Current RL for Lands Department PM's or SSM's
