Surface Water Management subareas for Western Australia were derived in consultation with the regional offices, and geometry is based on hydrographic catchments. Regional Department of Environment officers identified areas of similar management requirements to define boundaries or aggregations of hydrographic subcatchments. Regions with notable management concerns both currently and possibly in the future were identified to become management subareas. Management subareas will be used in the calculation of sustainable yields, flow rates and ultimately these calculations will be available for water allocation and natural resource management decisions. In addition, native vegetation clearing values have been calculated for each of the subareas located within the extent of the South-West region of Western Australia, for input into the allocation process. The Surface Water subarea data was developed in order to give a clear understanding of surface water availability and to provide management tools to make good water allocation and natural resources management decisions. Dataset was formerly known as Surface Water Management Subareas (DOW-021)

Surface Water areas stored in WRIMS (Water Resource Information Management System). For the purposes of Surface Water resource management, the state of Western Australia is divided into Surface Water areas. The extraction and licensing of surface water resources are managed within surface water areas in order to ensure environmental requirements are met and to prevent over extraction of the resource. Surface Water Management Areas for Western Australia were derived in consultation with the regional offices, geometry is based on hydrographic subcatchments. Regional Department of Water and Environmental Regulation officers identified areas of similar management requirements to define boundaries. Management areas will be used for licencing and administrative purposes.

For the purposes of groundwater resource management, the state of Western Australia is divided into groundwater areas proclaimed under the Rights in Water and Irrigation Act 1914. These groundwater areas are further subdivided into groundwater subareas. The subareas are not proclaimed, but are administrative boundaries used to manage the abstraction and licensing of groundwater resources.

This layer is to be used in conjunction with the WSPA layer. It represents individual zones within a specific Water Supply Protection Area.

Surface Water - This dataset displays Victoria's surface-water Water Supply Protection Areas (WSPAs), and has been prepared for the Groundwater and Licensing Branch and the River Health Branch DSE, by LICS (Land Information Cartographic Services) and Melbourne Water. As part of the 2002 amendments to the Water Act 1989, surface-water was included to allow WSPAs to be declared for the protection of surface-water resources in a defined area. A legally enforceable Streamflow Management Plan is then developed. The aim of the plan is to manage the surface water resources of the WSPA equitably and to ensure the long-term sustainability of the resource. An extensive consultative process guarantees that surface water users have a major input into the development of the Streamflow Management Plan for their area. A Ministerial appointed Consultative Committee which represents all relevant interests prepares the Plan. In an area where farming predominates, farmers who own or occupy farming land in the area must comprise at least half of the membership of the committee. Groundwater - This dataset displays Victoria's groundwater Water Supply Protection Areas (WSPAs), and was originally prepared for Groundwater and Licensing Branch DSE, by LICS (Land Information Cartographic Services). Boundaries generaterd by LICS and Melbourne Water. Subsequent revisions have been undertaken by GLiB and the Rural Water Corporations. WSPAs are areas that have been (or are proposed to be) proclaimed under the Water Act 1989 for the purpose of establishing a management plan.

This layer provides the boundaries of the River Basins of Victoria, and is part of a system devised by the Australian Water Resources Council (AWRC). The basins within Victoria are contained within two drainage divisions; the Murray Darling Division and the South East Coast Division.

A representation of South Australia’s surface water linear drainage network. Includes significant artificial drainage structures such as urban stormwater channels and the South East drainage scheme. This dataset has been created by merging a wide range of state and federal spatial datasets in order to extract the most accurate spatial and textual data for each region of the state. The dataset utilises a consistent national data schema (AHGF) but the geometry varies in accuracy, capture scale and completeness. Ideally viewed in conjunction with the Waterbodies dataset.
