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/).

The "Urban Water Management Strategies and Plans" (previously titled Urban Water Management Plans) dataset relates to integrating the land use planning system with planning for water management. The preparation of water management plans and strategies ensures that water is managed effectively in the urban form at each stage of the planning system. The dataset is used by the Department of Water and Environmental Regulation to identify drainage and water management plans, district water management strategies, local water management strategies, local water management frameworks and urban water management plans that have been prepared in accordance with the Better Urban Water Management (WAPC 2008) planning framework. The outline of the areas for drainage and water management plans and district water management strategies may be included when the draft report is in preparation. Local water management strategies and urban water management plans that have been approved by the Department of Water and Environmental Regulation shall be included in the dataset. Amendments to the planning approval process occurred in October 2008 with the introduction of Better Urban Water Management (WAPC 2008). Reports prepared previously such as Drainage and Nutrient Management Plans, Nutrient and Pollutant Management Plans and Integrated Water Management Strategies, do not accurately correspond with a category outlined in the Better Urban Water Management framework. These plans have been allocated to the most appropriate category and may not be consistent with the requirements outlined in Better Urban Water Management. Dataset was formerly known as Urban Water Management Strategies and Plans (DOW-031)

This dataset supercedes a previous Water Demand Region dataset (also called Monash Demand Regions). The regions in the current dataset have been developed using 2011 ABS Statistical Area Level 2 (SA2) boundaries, aggregated to best match previous Water Demand Region boundaries. The current dataset has 24 regions, while the previous version had 20. This dataset was developed for use in a new water demand-supply model. This dataset was formerly known as Water Demand Region Boundaries (DOW-059)

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)

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)

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.

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.

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)
