Bonalbo flood study

LATEST NEWS:

Kyogle Council has voted unanimously to place the draft Bonalbo Flood Study on public display and seek submissions on the document from the community. To review the draft Flood Study and make comment please click here

ABOUT THE PROJECT:

Kyogle Council have engaged engineering consultant BG&E to develop a Flood Study for Bonalbo . The study is being undertaken with financial and technical assistance from Council and Department of Planning, Industry and Environment (DPIE) through the NSW Government’s Floodplain Management Program. 

The Flood Study will help us understand the likely flooding scenarios for the town of Bonalbo including flooding from Peacock Creek and runoff from local catchments. 

The Bonalbo Flood Study will:

  • Develop flood models based on historic data and statistical analysis
  • Identify the areas of flood prone land to assist with flood planning and risk management
  • Consider the effect of the Bonalbo Dam on flood risk
  • Establish the likely flood risk and flood hazard for properties in the study area
  • Develop flood mapping to assist in future planning and development
  • Provide flood intelligence to the NSW SES to assist in flood emergency response

THE STUDY AREA:

THE FLOODPLAIN RISK MANAGEMENT PROCESS:

The Study is being prepared in line with NSW Government Policy and the Floodplain Risk Management Process. The process consist of 5 key stages. The Bonalbo Flood Study will complete Stage 1 and 2 (Data Collection and Flood Study). Once complete, the findings of the Flood Study will enable Council to start to the next step in the Floodplain Risk Management process; that is consider measures to reduce impacts of flooding. 

COMMUNITY QUESTIONNAIRE:

Thank you for your responses to the community questionnaire. The questionnaire has now closed. We received a great response with many of you providing photos which are helpful in validating the flood modelling results. If you have further information please use the email address under the contacts section of this page.

PUBLIC EXHIBITION OF DRAFT FLOOD STUDY:

Detailed hydrologic analysis and hydraulic modelling has been undertaken to map the predicted flood extents, levels, depths, velocities and hazards associated with a range of possible flood types from a 1 in 5 year flood, up to a 1 in 500 year event and the PMF Event (Probable Maximum Flood). The study also considers the predicted effects of climate change on flood behaviour. The information collected from the community about their community’s experiences of flooding has been used to validate the flood model against actual observed flood events.

Council also plans on arranging a presentation and a Q&A session with the community in early September. Please register your interest by providing your name, address, telephone number and email here: This email address is being protected from spambots. You need JavaScript enabled to view it..

The draft Bonalbo Flood Study will be on public display until 4pm 23rd September 2021. It can be viewed at the following locations;

  • Bonalbo post office
  • Old Bonalbo post office
  • Kyogle library
  • Kyogle Council administration building
