Council has prepared flood information maps that show areas possibly impacted by flooding, a recommendation of the Queensland Floods Commission of Inquiry (2011).

You can also go to Council's interactive mapping, where you view different layers from inundation flooding, river and storm tide flood extents plus flood gauges and bushfire prone areas.
Note about these maps
These maps have been produced in response to the recommendations of the Queensland Floods Commission of Inquiry (2011) to promote awareness of potential flood prone areas.
The information is of a general nature. It is not intended to replace the need for site specific enquiry of council records or to be a substitute for more formal flooding investigation required in any development approval or permit process.
These maps are intended to give an idea of how impacted an area might be in different flood severities (minor, moderate, major and extreme). If an area is shown as affected by:
- a minor flood extent – it could be expected to be impacted regularly (at least every two years)
- a moderate flood extent – it will probably be affected by flooding twice every ten years
- a major flood extent – there is a chance it will be affected once or twice in a lifetime (about 70 years).
Areas shown as affected by an extreme flood event are less likely to flood than the major flood.
Areas outside these flood extents are not expected to be impacted by riverine flooding.
The information presented on these maps is either model based, derived from historic flood data, or estimated using the best judgement of a professional hydrologist. The maps are not accurate to the scale of a specific property. In some areas flood information is not available.
Input data to this mapping consists of terrain data inputs captured through ground survey, Aerial Laser Survey (ALS) and rainfall/catchment data from the Bureau of Meteorology and other applicable engineering guidelines. Council regularly reviews and updates its flood models to incorporate the latest computer modelling techniques, terrain and climatic factors.
This ALS data is captured periodically, so the mapping may show inundation of land that has recently been filled, such as a new subdivision. Future updates will aim to rectify these differences.
The maps do not show the depth or the velocity of the water. They show only the extent (area) of flood waters. A flood search certificate can provide the water surface elevation (mAHD) for a specific property.
The maps represent only the inundation caused by the peak water level. They do not give any guidance on the duration of the inundation.
