The Geofabric Hydrology Reporting Regions version 3.3 dataset supports products such as the Bureau of Meteorology’s [Australian Water Resources Assessment (AWRA)]. Region boundaries are derived from grouped contracted catchments in the Geofabric Hydrology Reporting Catchments dataset. While originally designed for AWRA, these regions are suitable for broader national and regional hydrological reporting. The dataset includes three tiers of reporting regions: * AWRA Drainage Divisions: National-scale boundaries used in the 2010 Assessment (also referred to as the 2010 Assessment Reporting Regions). * River Regions: Regional-scale boundaries developed by Bureau hydrologists, the Geofabric team, CSIRO and ANU scientists. These support regional reporting and hydrological modelling. They were not used in the 2010 Assessment but may be included in future reports. * Station Catchments: Local boundaries representing upstream contributing catchments for key gauging stations across Australia. These reporting regions are available through five data types: 1. AWRA Drainage Division 2. River Region 3. Station Catchments 4. AWRA Drainage Division Contracted Catchment Lookup (table) 5. River Region Contracted Catchment Lookup (table) Additional reporting regions may be included in future versions, depending on user needs.

It shows boundaries used for reporting on Australia’s water resources. These boundaries are based on groups of contracted catchments from the Hydrology Reporting Catchments dataset. The product includes two types of reporting regions: * AWRA Drainage Divisions – used for national-scale reporting, including the 2010 Australian Water Resources Assessment. These divisions were based on Level 1 Drainage Divisions from the Geofabric Surface Catchments dataset, with one extra division added to separate New South Wales and Victoria. This created two new regions: South East Coast (NSW) and South East Coast (Victoria). * River Regions – used for regional-scale reporting and hydrological modelling. These were developed by Bureau hydrologists with input from the Geofabric team, CSIRO and ANU scientists. They are based on Level 2 Drainage Basins from the Geofabric Surface Catchments dataset, except in the Murray–Darling Basin, where more detailed boundaries were needed. More reporting regions may be added in future versions based on user needs. How the data was processed: 1. Feature classes in the Geofabric Maintenance Geodatabase were given unique HydroIDs using ESRI ArcHydro for Surface Water. 2. These feature classes were then moved into the Geofabric Hydrology Reporting Regions dataset. The Digital Atlas of Australia team at Geoscience Australia made small updates to this dataset for online use. They fixed some geometry issues and improved map features like visibility, labels and symbols. These changes help make the dataset easier to access and faster to use.
