Flood awareness information

Natural disasters like floods are tough for communities and individuals. Helping Logan be flood aware, ready, and resilient is important to us. Accurate and updated flood information helps residents make informed decisions about flood risks.

Logan City Council is undertaking a Flood Studies Review Program to provide updated information on flooding and flood mapping. This will help us to better protect our community against future flooding events. You can find information about our Flood Studies Review Program our Question and Answer factsheet.

Updated flood information will be available in the Flood Report on the Logan PD Hub from 17 October. This updated information is from the recently completed flood studies (please refer to the table at the end of this page for the status of flood studies). More information about how to use the Logan PD Hub is available on our PD Hub webpage. To learn more about the information on the Flood Report, please see our Flood report factsheet.

You can also read our Media release or view the Mayor talking about the recent flood mapping our Youtube channel.

If you would like to speak to someone about the updated flood study, please call us on 3412 3412. You can also email us at Council@logan.qld.gov.au.

We understand thinking and talking about floods can be distressing. Having well-informed planning, useful and timely information before, during and after a flood event can help us all to be flood aware, ready, and resilient.

Understanding your flood risk can help you prepare for flooding at your home or business.

There are steps you can take to minimise the impact of floods.

Before a flood

During a flood

We have installed a number of flood-watch cameras around Logan. You can check the cameras to find out creek levels across the city. They will help you prepare and plan for flooding and find different routes when there are road closures. You can view the cameras 24-hours a day. During the night, the quality of the image may change due to lighting.

Visit our Disaster Dashboard for camera feeds and the latest information on weather warnings, road closures, power outages and evacuation centres.

You should also:

  • secure objects that could float away and cause damage
  • check social media, listen to your radio or watch television for the latest information and warnings.

If you have to leave your home during a major flood:

  • turn off the electricity, gas and water at the mains
  • take your emergency kit
  • take your pets with you
  • consider staying with friends or family in safer areas – wherever you go, let others know.

More information can be found on the Get Ready Queensland website. 

Remember, once you enter floodwaters, you are giving up control of your vehicle. If it's flooded, forget it!

Disclaimer: We make every effort to ensure the flood camera images are as accurate as possible. There is no validation of this information. It is your responsibility to make decisions about the currency, accuracy and completeness of the information and images. We accept no responsibility or liability for any loss or damage incurred as a result of this information or its use in any way.

After a flood

  • visit our Disaster Dashboard for updates on roads re-opening, power outages and weather warnings
  • be careful when returning to your home after a flood. Do not enter floodwaters
  • floodwater can be full of bacteria, so wear shoes at all times and do not allow children to play in or around flood waters
  • record details of flood damage by taking photos or video for insurance purposes
  • don't use gas or electrical appliances that have been flood-affected until checked by a service provider
  • do not eat food that has been in contact with floodwater
  • boil all tap water until the water supply is safe.

Flood studies and modelling

Logan is a green city. We value our natural environment and the 2 major rivers (the Logan and the Albert River) and approximately 50 creek catchments it includes. Understanding our flood risk helps us to:

  • protect people and property
  • avoid making flooding worse, and
  • support our emergency response and evacuation.

Council has a rolling Flood Studies Review Program to help us improve our understanding of the flood risk across Logan’s different catchments. We take into account State legislation, policies and guidelines and a range of factors such as climate change, new rainfall and river level information from recent flood events, growth in our city, catchment conditions, new technology and industry best practice. We work with specialist consultants to deliver updated flood modelling and studies. In line with the recommendations of the Queensland Floods Commission of Inquiry, we share that information with our community to help keep people and property safe. Updated flood studies will be published here, to help our community be flood aware, ready and resilient. Property maps are available in the free online Flood Report in our Logan PD Hub

The table below outlines the status of flood studies and provides links to the relevant documents for accepted studies. You can download a Logan Flood Studies map (PDF 3 MB) that shows the extent of the area covered by each flood study. For further information or for help understanding the flood risk on your property, please contact Council.

Past floods

The flood hazard mapping used for planning and awareness purposes does not represent any specific actual flood. It is a prediction based on studies and modelling completed with the best available information. The inputs include the behaviour of flood water in actual flood events that have occurred in Logan in past years. There have been a number of significant floods in the City of Logan. More recent events are listed in the table below with their approximate size using the scale of Annual Exceedance Probability (AEP). A 1% AEP means there is a 1 in 100 likelihood of a flood of this size occurring in any given year.  It does not mean that a flood of that size will only occur once in every 100 years.

A lower likelihood represents a more serious flood, i.e. flood levels in a 1% AEP event would be higher than those experienced in a 2% or 5% AEP event. Each flood is unique, and any given flood will have different impacts in different areas. Properties impacted by a 1% AEP flood in one year may experience different impacts in a 1% AEP flood in another year.

Notes

February/

March 2022

2%-5% AEP flood

2%-5% AEP flood

1%-2% AEP flood

1%-2% AEP flood

The Logan River experienced the highest levels since 1974 in the urban areas, although peak levels were very similar to the 2017 flood. Whilst the Albert River experienced a significant flood event in 2022, the 2017 flood remains the largest since 1974.

March 2017

(from ex Tropical Cyclone Debbie)

2%-5% AEP flood

 2%-5% AEP flood

 0.5%-1% AEP flood (slightly greater than 1%)

Approx. 0.2% AEP flood (new record)

According to the Bureau of Meteorology this flood (March 2017) was the most severe in recent memory, with new record flood levels set along the Logan River at Beaudesert and Maclean Bridge, and a new record at Bromfleet for the Albert River. Beenleigh experienced its highest flood since 1887.

January 1974

2%-5% AEP flood

1%-2% AEP flood

 Not available

1%-2% AEP flood

In 1974 the Maclean’s Bridge gauge was in a different location.

This event (1974) is the closest to a 1% AEP flood that Logan has experienced in recent times.
