This dataset is under review, please contact DWER for access to updated version. This dataset is a catalogue of current & historic boundaries of Water Allocation Plans and Statements and associated attributes. Each boundary indicates the area covered by the plan or statement. Water Allocation Plans may also be known as Water Management Plans. This dataset is intended to aid in water resource management.

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)

The dataset shows the location and spatial extent of aquatic ecosystems and their potential dependence on the surface expression of groundwater. It shows aquatic ecosystems at a scale of 1:100 000 and is best viewed at this scale. Not all ecosystems are present in the dataset, smaller aquatic ecosystems requiring a higher resolution are not displayed. Aquatic ecosystems that are known or likely to interact with groundwater in their hydrological cycle are potentially groundwater-dependent. The aquatic groundwater-dependent ecosystem (GDE) dataset shows the location of aquatic ecosystems and their GDE potential in the Fitzroy water planning area. The aquatic ecosystems included in the final dataset are categorised as: + Base-flow rivers + Wetlands + Estuarine and near shore marine + Springs. River base flow systems – River systems and associated riparian vegetation are unique ecosystems providing a habitat for threatened and priority flora and fauna, including native aquatic species and birds. Base flow is a component of the total stream flow that is supported by groundwater discharge. River permanence and flow duration indicate groundwater dependence during periods of low or no rainfall supporting differing ecosystem processes. There are several permanent riverine pools found on the main Fitzroy River channel. WETLANDS – wetlands that have a known or likely element of groundwater discharge in their hydrological cycle will be considered groundwater dependent. Wetlands are areas of seasonally, intermittently or permanently waterlogged or inundated land, whether natural or otherwise, such as lakes, swamps, pools, springs, and damplands. The hydrogeology of the Fitzroy water planning area is complex and variable. Hydrogeology mapping and a hydrogeologist should be consulted to determine the groundwater source of a wetland. ESTUARINE AND NEAR SHORE MARINE - Estuarine habitats are classified as components of an estuary, partially enclosed by land, with a continuous or intermittent connection to the ocean. With a freshwater influence from overland run-off, there is diluting and mixing of seawater. These habitats can include estuarine wetlands, lagoons, salt marshes, and mangroves. Near shore marine habitats are exposed to the waves and currents of the open ocean. Their water regimes are dominated by the ebb and flow of the ocean and tend to have a high salinity, normally greater than 33%. These habitats include seagrass meadows, coral, and stromatolites. The Fitzroy, May, Meda, and Robinson Rivers flow into the King Sound, supporting many different near shore marine habitats. Seagrass meadows, mangrove forests and salt flats are known to occur in and around the King Sound. SPRINGS - Springs provide a permanent source of freshwater and are recognised as important aquatic ecosystems found throughout the Australian landscape. The occurrence of permanent water in arid landscapes provides stable long-term habitat, critical to flora and fauna during dry periods, especially in the north-western region of Western Australia. A spring can be described as having a permanent discharge or flow of groundwater at the surface.

These datasets represent management units within in-force water sharing plans across NSW, including regulated, unregulated and groundwater plans (or a combination of these). The data includes both water sources and management zones (where applicable) derived from plans gazetted under the NSW Water Management Act 2000. The boundaries of these water sources and management zones are used to define areas in which specific management rules apply. As such, this data may be used to understand which water sharing plan rules apply to a specific location. The plans are in place for 10 years but may be amended within this time. Any updates to water source or management zone boundaries as a result of a plan being amended during, or replaced following its 10 year term will be made available at that time. PLEASE NOTE: In the case of any discrepancy between this digital dataset and the published Water Sharing Plan (accessible on the www.legislation.nsw.gov.au site) the instrument as made by the Minister remains the authoritative source and should be used to both interpret the intent of the Plan and in subsequent decision making. Best endeavours have been made in collating relevant Water Sharing Plan boundary and attribution contained in this dataset. However, no warranty is provided as to the accuracy or currency of this representation. The department does not warrant and is not liable for the use of this material as per the licenced sharing conditions CC-BY 4.0.

As part of the stages of water restriction, the Department of Water and Environmental Regulation prepared a state map contained four different areas of water restrictions which are controlled by the Water Agency (Water Use) by-laws 2010. Dataset was formerly known as Sprinkler Restrictions - Water Agencies (Water Use) Bylaws (DOW-064)

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)

The Surface Water Resources (SWR) dataset was created to assist licensing and management of surface water in Western Australia. A surface water resource represents the smallest area to which water is managed. Surface water resources are the boundaries to which allocation limits are set. The SWR dataset was derived from the Surfacewater Allocation Subareas (WRIMS) dataset and SDL catchments dataset, resource boundaries align with mapping shown in all draft and current Water Allocation Plans.
