This dataset contains the extent, name and unique ID number of the Drainage Divisions in the State of Queensland, as defined by the Australian Water Resources Management Committee (WRMC).
Resource purpose/summary
To provide an authorative single point of truth for the extent of Drainage Divisions in the State Queensland. It is suitable for use in land administration, emergency and water management, monitoring of climate change, hydrological modelling, topographic and vegetation mapping and in the production of navigational and web based mapping applications.

Dataset created and owned by Department of Resources for the State of Queensland using base information owned by Federal Government Agencies and has no use limitations.
Unrestricted to all levels of government and community. Data is available to all government agencies, community groups and individuals. Dataset is available through physical supply and may be made available via web delivery tools, for example, through DNRME's internet sites.
Supplemental information about the data
The dataset was captured at 1:100 000.
The seaward edge of this data aligns with the Coastline and State Border - Queensland dataset.
Feature Types: DRAINAGE DIVISION - A region of land where water from rain drains downhill into a body of water, such as a river, lake, dam, wetland, sea or ocean. The extent of land covered by a drainage division was originally determined by the Australian Water Resources Management Committee (WRMC) and generally follows the major watersheds.
Attributes: DIV_NAME - The name of the Drainage Division DIV_NUMBER - A unique number allocated to the Drainage Division
Australia is divided into a number of Drainage Divisions. Queensland is covered by five Drainage Divisions - Bulloo, Gulf, Lake Eyre, Murray Darling and North East Coast and are each allocated a unique ID number
Flow is determined using low rainfall. It areas of flat terrain, high rainfall can cause water to flow across watersheds.
This dataset is stored in an ESRI Geodatabase. Some columns names may be shortened if downloaded in the ESRI shape format.

Data Lineage
Lineage statement, a general explanation
The location of Australia’s Drainage Divisions were originally defined by the Australian Water Resources Management Committee (WRMC). The divisions generally follow the major watersheds e.g. The Great Dividing Range. To accurately plot the location of the boundaries, the definition of the divisions were compared with 1:100000 topographic mapping (published and unpublished) and the location of the watershed based on the contours was plotted onto hard copy maps. These plotted lines were later digitised to create a spatial dataset. With the 1:250000 drainage network as a background, checks were made to ensure that no drainage lines crossed a division boundary.
In 2020, the seaward edge of the data was moved to align with the Coastline and State Border - Queensland dataset.
