Up to date information about the extent and location of surface water provides all Australians with a common understanding of this valuable and increasingly scarce resource. Digital Earth Australia (DEA) Waterbodies shows the wet surface area of waterbodies as estimated from satellites. It does not show depth, volume, purpose of the waterbody, nor the source of the water. DEA Waterbodies uses Geoscience Australia’s archive of over 30 years of Landsat satellite imagery to identify where over 300,000 waterbodies are in the Australian landscape and tells us the wet surface area within those waterbodies. It supports users to understand and manage water across Australia. For example, users can gain insights into the severity and spatial distribution of drought or identify potential water sources for aerial firefighting. The tool uses a water classification for every available Landsat satellite image and maps the locations of waterbodies across Australia. It provides a timeseries of wet surface area for waterbodies that are present more than 10% of the time and are larger than 2700m2 (3 Landsat pixels). The tool indicates changes in the wet surface area of waterbodies. This can be used to identify when waterbodies are increasing or decreasing in wet surface area.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Cooper Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Cooper Basin, including streamflow quality and quantity, inundation, and climatological data. The Cooper Basin underlies 3 surface water catchments: the Diamantina River, Cooper Creek and Bulloo River. All 3 rivers follow a similar flow pattern, with most of the run-off generated in the higher rainfall headwater areas (outside the Cooper Basin) before flowing down into extensive floodplains and ending up in terminal lake systems. The data on the catchments overlying the Cooper Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Galilee Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Galilee Basin, including streamflow quality and quantity, inundation, and climatological data. The Galilee Basin straddles the Great Dividing Range and encompasses the headwaters of 9 major river basins, with the largest area underlying Cooper Creek, Diamantina River and Flinders River catchments. The Galilee Basin geological boundary also intersects parts of the catchment of the Burdekin River, Fitzroy River, Warrego River, Bulloo River, Paroo River and Condamine-Balonne rivers. The data on the catchments overlying the Galilee Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the north Bowen Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the north Bowen Basin, including streamflow quality and quantity, inundation and climatological data. Most of the north Bowen Basin falls to the east of the Great Dividing Range within the Fitzroy River catchment. The basin also includes part of the Burdekin River catchment and small parts of the coastal catchments of Styx and Burnett river catchments. The data on the catchments overlying the north Bowen Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are available from the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Adavale Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Adavale Basin, including streamflow quality and quantity, inundation, and climatological data. The Adavale Basin underlies 3 main surface water catchments that contribute to Cooper Creek, including the Barcoo, Bulloo and Warrego rivers. The Adavale Basin geological boundary also intersects the upper parts of the Paroo River catchment and a small part of the Condamine-Balonne catchment. The data on the catchments overlying the Adavale Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.
