Description: The data represents maximum inundation for historical flood events over Queensland. The flood lines have been captured from a variety of data sources, including digitized scanned maps, Aerial Imagery and Satellite Imagery. This information is found in the feature reliability attribute.
Description: This data represents the maximum innundation line polygon of the Bremer River and Brisbane River floods in January 1974.
The Bremer River flood was captured by the Ipswich City Council whilst the Brisbane River flood was captured by the Brisbane City Council. The line is based on surveyed levels captured after the event from debri lines. The dataset was digitised from Ipswich City Council and Brisbane City Council mapping.
Description: The data consists of polygons that indicate the approximate inundation at the time the source aerial imagery was captured.
The data was captured by Spatial Information Officers using MapInfo GIS software. Capture scale varied across the state. The data is recommended for use at a scale of 1:5000 or above in the Brisbane area and 1:7500 or above in other parts of the state. This data has not been ground verified.

Description: This data over South West Queensland consists of a polygons that indicates approximate inundation at the flood peak.
The data was captured by Spatial Information Officers using MapInfo GIS software. Capture scale is 1:5000, recommended scale for use of data is 1:7500 or greater. This data has not been ground verified.
Description: The layer consists of polygons that indicate the approximate inundation in the Bunbaberg area on 29th January 2013.
The inundation line was captured using debris lines where evident on image, LiDAR contours and damage reports supplied by the Queensland Reconstruction Agency.
The data was captured by Spatial Information Officers using MapInfo GIS software. Capture scale is 1:5000, recommended scale for use of data is 1:7500 or greater. This data has not been ground verified.
Description: This dataset represents the maximum inundation of the April 2017 flood in the Connors, Fitzroy, Issac and Mackenzie Rivers following the heavy deluge of rain from ex-Cyclone Debbie.
This dataset was digitised from 3 metre satellite imagery taken near the height of the flood.
The completeness of the data is dependent upon image quality and the ability to identify feature detail e.g.
• The floodwater had receded at the time of image capture but the landscape was still heavily inundated from later rainfall.
• Some areas within the mosaic were not captured due to the flight paths of the satellite not overlapping or adjoining. (in these areas the flood line was maintained by holding the approximate contour height) • The mosaic can have uneven colour balance.
This dataset was captured by Spatial Information Officers using ESRI ArcGIS software.
Capture scale is 1:12 500, recommended scale for use of data is 1:25 000 or greater. Note: This data has not been ground verified.
Description: This dataset represents the maximum inundation of the April 2017 flood in the Logan and Albert Rivers following the heavy deluge of rain from ex-Cyclone Debbie. This dataset was digitised from 15 cm orthophotography and 3 metre satellite imagery taken near the hieight of the flood. The completeness of the data is dependent upon image quality and the ability to identify feature detail e.g.
• The imagery can be compromised by cloud shadows. • Sun reflection can also further confuse water interpretation. • The floodwater had receded at the time of image capture but the landscape was still heavily inundated from later rainfall. • Some areas of cultivation are low lying and normally inundated with heavy rain, often being confused as flooding where they adjoin the flood path.
• The mosaic also can have uneven colour balance.
• Some areas within the mosaic were not entirely covered by the imagery and whiteout occurred in certain areas. This dataset was captured by Spatial Information Officers using ESRI ArcGIS software. Capture scale is 1:2500, recommended scale for use of data is 1:5000 or greater. Note: This data has not been ground verified.
Description: This data represents the maximum inundation of the February 2019 flood over Western Queensland covering the Flinders and Diamantina River catchment areas following an extreme weather event, caused by a remnant monsoonal low.
Data was captured from an RGB 3m PlanetScope moaiced temporary image service. This was used to perform a supervised image classification to generate an intial vector polygon, which was then manually checked and modified to represent the inundation area at the time of satellite capture. For upstream areas on the Flinders Catchment area that had flooded earlier in the event when still under cloud and had no flood water present in the Planet imagery, Sentinel2 imagery was used to manually digitse flood extents. This dataset was captured by Spatial Information Officers using ESRI ArcGIS software.
Capture scale is 1:5000, recommended scale for use of data is 1:15000 or greater.
Name: Modelled Possible Flood Data - Referable Dams
Display Field:
Type: Group Layer
Geometry Type: null
Description: The data represents modelled maximum possible inundation areas supplied by dam owners. The data represents various forms of dam failures. The dams are described as Referable dams. A dam is referable if a failure impact assessment demonstrates there would be 2 or more people at risk if the dam was to fail. The flood extents displayed within this data was created by individual dam owners using a range of flood modelling techniques, based on survey and spatial data sets of differing ages and quality. Some dam owners may have used different modelling techniques for individual dam sites. These individual flood extents have been merged to create a state wide dataset. This dataset is updated regularly when new flood extents are received from dam owners and will reflect the contents of published emergency action plans.
Description: This dataset describes the flood extents as a result of a Sunny Day Failure (SDF) for the referable dams in Queensland. SUNNY DAY FAILURE - The predicted extent of a flood caused by a dam failure event that occurs without a wet weather event. The flood extents displayed within this dataset were created by individual dam owners using a range of flood modelling techniques, based on survey and spatial data sets of differing ages and quality. Some dam owners may have used different modelling techniques for individual dam sites. These individual flood extents have been merged to create a state wide dataset. This dataset is updated regularly when new flood extents are received from dam owners and will reflect the contents of published emergency action plans.
