Hydro Bores is a point feature of the location of publicly available bore monitoring sites maintained by the Department of Primary Industries and Regional Development. They are part of a network of bores designed to monitor regional scale salinity risk and salinity management trial sites. For further information refer to Department of Agriculture Resource Management Technical Report No.388. See also the 2014 report card - Groundwater trends in agricultural areas of Western Australia.

Surface Water Management Areas for Western Australia were derived in consultation with the regional offices, geometry is based on hydrographic subcatchments. Regional Department of Environment officers identified areas of similar management requirements to define boundaries. Management areas will be used for licencing and administrative purposes. Purpose: The Surface Water Management Area 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 formally known as Surface Water Management Areas (DOW-020)

The zone managed for intensive agricultural activities in South-Western Australia. Also known as the South West Agricultural Area or Clearing Line. This zone defines the easternmost extent of land cleared for agricultural purposes. Base data sets: Western Australian Land Information Authority - Captured from photographic interpretation of best available orthophotography at date of capture, dates range between 2007 and 2010. Scale of capture: 1:20,000

This dataset is the Western Australian component of a national Drainage Divisions and Basins dataset overseen by the Australian Water Resources Council. It is part of a hierarchical order of 4 datasets ranging from Subcatchments through Catchments and Basins to Divisions. The Subcatchments, Catchments and Basins are hierarchically ordered subsets of the Divisions dataset. Catchment boundaries have been defined for more than 3400 key sites on streams throughout Western Australia. The Subcatchments dataset contains polygons from which the Catchment boundaries are derived. This catchments dataset is derived from this on the basis of the CATCH_NAME field, determined by the Scientific Custodian. This dataset was formerly known as Hydrographic Catchments - Catchments (DOW-014)

This dataset is the Western Australian component of a national Drainage Divisions and Basins dataset overseen by the Australian Water Resources Council. It is part of a hierarchical order of 4 datasets ranging from Subcatchments through Catchments and Basins to Divisions. The Subcatchments, Catchments and Basins are hierarchically ordered subsets of the Divisions dataset. The drainage divisions of Western Australia, derived from catchment boundaries defined at various scales. This dataset is derived from a subset of lines from the Hydrographic Catchments - Subcatchments data. This dataset was formally known as Hydrographic Catchments - Divisions (DOW-016)

This dataset is the Western Australian component of a national Drainage Divisions and Basins dataset overseen by the Australian Water Resources Council. It is part of a hierarchical order of 4 datasets ranging from Subcatchments through Catchments and Basins to Divisions. The Subcatchments, Catchments and Basins are hierarchically ordered subsets of the Divisions dataset. The drainage basins of Western Australia, derived from catchment boundaries defined at various scales. This dataset is derived from a subset of lines from the Hydrographic SubCatchments data. This dataset was formerly known as Hydrographic Catchments - Basins (DOW-013)

This dataset is the Western Australian component of a national Drainage Divisions and Basins dataset overseen by the Australian Water Resources Council. It is part of a hierarchical order of 4 datasets ranging from Subcatchments through Catchments and Basins to Divisions. The Subcatchments, Catchments and Basins are hierarchically ordered subsets of the Divisions dataset. Catchment boundaries have been defined for more than 3400 key sites on streams throughout Western Australia. The Subcatchments dataset contains polygons derived from all the defined boundaries, while the Catchment, basin and division polygons are based on subsets of the same boundaries. This dataset was formerly known as Hydrographic Catchments - Subcatchments (DOW-015)

Groundwater areas proclaimed under the Rights in Water and Irrigation Act, 1914. For the purposes of groundwater resource management, the state of Western Australia is divided into groundwater areas. The extraction and licensing of groundwater resources are managed within groundwater areas. This dataset was formerly known as RIWI Act, Groundwater Areas (DOW-012)

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.

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)
