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. 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)

The DWER Water Information Sites dataset lists monitoring locations (sites) where surface water and groundwater data are collected to assess the quality and quantity of state water resources. This monitoring supports a comprehensive understanding of the state's water assets and underpins evidence-based decision-making for both regulatory and resource management purposes. Please note that the dataset presents only summary-level attribute information for each site. It does not include all available data, which may encompass individual measurements such as water depth, stream height, water quality, rainfall, and bore details including construction, lithology, and stratigraphy. For access to detailed data, please visit the Water Information Reporting (WIR) system. (https://wir.water.wa.gov.au/).

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)

Groundwater areas stored in WRIMS (Water Resource Information Management System). For the purposes of groundwater resource management, the state of Western Australia is divided into groundwater management areas or groundwater areas. The extraction and licensing of groundwater resources are managed within groundwater areas in order to ensure environmental requirements are met and to prevent over extraction of the resource. Some Groundwater Areas stored in WRIMS do not accurately reflect the official gazetted Groundwater Area boundaries, however a program is currently underway to realign the boundaries. Please contact the data steward for more information.

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)

This dataset presents locations of regional surface hydrological features in Australia as points at a higher resolution than that of the national dataset. The following features are included in this dataset: Bore - A small diameter hole in the ground for the purpose of obtaining subterranean water by natural flow or mechanical pumping. Dam - An open body of water collected and stored behind a constructed barrier consisting of earth, rock, concrete and/or masonry. Generally designed to capture run-off from the surrounding landscape or rainfall. The storage of water may occur on or below ground level. Lock - An enclosure in a water body with gates at both ends to raise or lower the water level to enable vessels to pass from one level to another. Gnamma Hole - Small holes of varying shape, diameter and depth, found in hard granite outcrops and in the decomposed granite of a breakaway, which can and usually does hold water. Native Well - An isolated natural depression which holds water, not within Watercourses. The natural phenomena is sometimes improved by indigenous persons for their own water collection purposes. Pool - A small body of still or standing water, permanent or temporary in an isolated natural depression, not within Watercourses. Rockhole - A hole excavated in solid rock by water action. Soak - A depression holding moisture after rain, especially the damp or swamp spots around the base of granite rocks. Spring - A place where water issues from the ground naturally. Waterfall Point - A sudden descent of water over a step or ledge in the bed of a watercourse. Waterhole - A natural depression which holds perennial water, within a non-perennial watercourse or a non-perennial lake. Water Tank - Water Tanks are storage containers for water, usually used for human consumption and other purposes such as irrigation, agriculture, fire suppression, agricultural farming and livestock, chemical manufacturing and food preparation. Water Tanks are constructed of various materials including plastic (polyethylene or polypropylene), fiberglass, reinforced concrete, steel (welded or bolted, carbon or stainless). Those used for human consumption are generally fully enclosed. For more information please visit the Geoscience Australia Web Service Portal.
