Flooding in Tuggerah Lakes can not be eliminated, says report
“The interim procedure seeks to allow natural entrance processes to operate with minimal disturbances in accordance with the Policy and guidelines for fish habitat conservation and management.
“Entrance works are to be undertaken immediately prior to flooding to assist in providing flood risk reduction.
“Regular ongoing entrance berm works to continuously maintain flood-ready berm conditions were not considered to be feasible given the highly dynamic nature of the entrance including berm rebuilding and channel infilling processes.
“The interim entrance management procedure is to be reviewed following flood events as required,” the conclusion stated.
The Interim Entrance Management Procedure was used to manage the channel during this year’s flood events, Council said.
“This procedure is supported by flood intelligence tools that provide real-time predictive lake level modelling and data to ensure a proactive and informed response from Council when flood events are predicted,” Council said.
“This Interim Procedure will be included in the SES’s Central Coast Local Flood Plan, which provides guidance on flood response.
“The Interim Procedure is intended to guide Council’s channel management until an Entrance Management Strategy can be completed through the Tuggerah Lakes Coastal Management Program.
“Community input will be sought as part of upcoming consultation on the Coastal Management Program, which is currently in development.”
Council met with the SES, police and State Members last week to discuss flood mitigation and preparedness.
Council told the meeting t had received funding from the NSW Government to review and update the 2014 Tuggerah Lakes Flood Study which will inform an updated Floodplain Risk Management Study and Plan.
“This project is now underway and will allow for an updated understanding of flood risk and behaviour within the Tuggerah Lakes floodplain in order to better identify and mitigate flood risk,” Council said.
“The updated study will be able to take into account intensified development within the catchment since the last study.
“It will not only update anticipated flood frequencies and heights, but also identify flood velocities within the floodplain to better understand current flood risks.”
