Tumbi Umbi Creek Floodplain Risk Management Review and Plan

Tumbi Umbi Creek has a catchment area of 14.25 square kilometres and discharges into Tuggerah Lake on the Central Coast of New South Wales. Tuggerah Lake is the largest of three interconnected coastal lakes which enter the Pacific Ocean via a single entrance at The Entrance. Parts of the catchment are classified as “flood liable” with the area inundated by the design one percent AEP flood covering some 1.1 square kilometres, while the Probable Maximum Flood is expected to inundate some 2.3 square kilometres.

The primary objective of the Tumbi Umbi Creek Floodplain Risk Management Review is to determine appropriate floodplain management measures for the preparation of a cost-effective Floodplain Risk Management Plan for the study area. The study addresses flooding caused by runoff in the Tumbi Umbi Creek and its tributaries and does not address flooding caused by elevated water levels in Tuggerah Lake independent of river flooding.
