National Catchment Boundaries

Dataset Uses

Government agencies use this data to better manage water resources. The Australian Hydrological Geospatial fabric (Geofabric) is released through the Bureau of Meteorology which provides a framework for discovering, querying, reporting and modelling water information aligned with the definitions under the Water Act 2007 .

Government agencies use this data to

  • Define administrative boundaries; catchments and aquifers can form the boundaries between adjacent state governments or other administrative areas
  • Model areas of interest
  • Manage Environmental assets
  • Water Accounting
  • Asset management and monitoring
  • Managing flood risk
  • Modelling water flow

Quality

The National Catchment dataset provides a seamless surface catchment layer for Australia. The dataset feature is based upon polygons converted from a regular 9 second grid delineating the surface for the Australian continent.

The Dataset includes a unique spatial identifier for each line feature. The identifier will be used to maintain the dataset and to incorporate higher resolution datasets in the future.

Current Status

Maintained by Geoscience Australia and derived from 9 Second DEM.

Current maintenance are revising priority areas by deriving from the 1 Second DEM.

Geoscience Australia provided inputs to the Bureau of Meteorology for the creation of Geofabric suite of products to meet the requirements of the National Water Account under the Australian Water Act 2007 and Water Regulations 2008 .

Future Status

Short Term objectives:

  • Fully aggregate all jurisdictional data into a national dataset providing a complete and consistent representation of the national surface hydrology network
  • Update priority catchment areas with the larger scale surface water inputs

Long term objectives include:

  • Continued spatial upgrades of all surface hydrology data using current and higher resolution imagery
  • Hydrological enforce data using improved elevation models

Key Users

Key users of the national catchments are Commonwealth, State, Territory and Local governments and the Research and Industry sectors
