VIC MWC - Drainage - River Basin Catchment (Polygon) Apr 2014

This dataset presents the boundaries of Australia's basins as defined by the Australian Water Resources Management Committee (WRMC). Australia is divided into drainage divisions which are sub-divided into water regions which are in-turn sub-divided into river basins. The data includes the name and number of each of the 245 drainage basins, 77 regions, and 12 divisions. Australia's River Basins 1997 is the result of a joint State, Territory and Commonwealth Government project to create a national spatial database of major hydrological basins.

The data has been aligned with Melbourne Water's drainage catchments, resulting in a consistent set of drainage catchment layers up to and including watersheds at the State level.

This dataset provides a consolidated and consistent set of drainage catchments covering the entire Port Phillip and Westernport catchment area (Melbourne Water's area of responsibility for waterways and drainage). The primary purpose of this layer is for the hydraulic modelling of catchments and waterways, and/or calculations. Additional uses:

• Asset creation and numbering

• Flood Plain Mapping

• Drainage Scheme Creation and Reviews

• Water Resource Management

• Responding to Land Development Enquiries
