River basin catchment areas for Melbourne. This layer has two intended purposes: To provide a readily available amalgamation of MWC_Catchments that make up the river basins within Melbourne Water’s area. Useful for larger scale plans and maps.Data for basin boundaries have been captured by relevant State and Territory authorities from 1:10 000 and 1:250 000 scale source material. The balance of the data are from Geoscience Australia's GEODATA Coast 100K which includes coastlines and State and Territory borders. Topographic Drainage Divisions and River Region boundaries are updated based on current research, data and technology. It references previous work of the Australian Water Resources Management Committee as shown in Australia's River Basins 1997. This work is a collaboration of scientists from the Bureau of Meteorology, Australian National University Fenner School of Environment and Society, CSIRO Water for Healthy Country Flagship and Geoscience Australia.In late 2008, the Bureau of Meteorology (BoM), in partnership with Geoscience Australia, CSIRO and the Australian National University (ANU) commenced the development of the Australian Hydrological Geospatial Fabric (Geofabric). Geofabric is being developed to underpin the Australian Water Resources Information System (AWRIS) within a single, consistent, national geospatial framework for hydrological features. Geoscience Australia's role in the Geofabric is to provide the best available national topographic spatial data for surface water features based on the National Topographic Data and Map Specifications. The river basin boundaries have been aligned (by Melbourne Water) to Melbourne Water Corporation (MWC) drainage catchments, to produce a consistent drainage and waterways catchment dataset to State level, since 2005.NOTE: Whilst every effort has been taken in collecting, validating and providing the attached data, Melbourne Water Corporation makes no representations or guarantees as to the accuracy or completeness of this data. Any person or group that uses this data does so at its own risk and should make their own assessment and investigations as to the suitability and/or application of the data.
