Description: Major streamlines of WA, coded with a hierarchy and are named. The dataset includes many streams in addition to the detailed Hydrography in areas where its data is limited (eg. Eastern Wheatbelt and Western Plateau). Dataset is designed to be evolving as more information becomes available (eg. Aerial Photography).
USAGE:
The Hydrography, Linear (Hierarchy) dataset is used by DWER for broad scale streamline presentation. It also provides definition of streamlines in ancient drainage landscapes, when other datasets do not have linework.
This dataset was formally known as Hydrography Linear (Heirarchy) (DOW-029)

Description: The Department of Water and Environmental Regulation produces floodplain mapping of rivers and major watercourses and provides floodplain development advice to ensure that proposed floodplain development has adequate flood protection and does not impact on the existing flood regime of the area.
This advice is related to major river flooding only. Other issues, such as stormwater drainage and envirionmental and ecological considerations are not addressed. This dataset contains the location of cross sections lines, indicating modelled / surveyed cross sections of the river channel and floodplain. The cross sections are labelled using chainage, which is generally defined as the distance from the DWERnstream start of a flood study traversing up the river. The cross sections are defined perpindicular to the flow direction and illustrate how the relevant flood levels are to be applied across the floodplain. Each cross section has an associated flood level listed in the attribute fields as follows:
FLDLVL_10 (1 in 10 (10%) AEP flood event)
FLDLVL_20 (1 in 20 (5%) AEP flood event)
FLDLVL_25 (1 in 25 (4%) AEP flood event)
FLDLVL_50 (1 in 50 (2%) AEP flood event)
FLDLVL_100 (1 in 100 (1%) AEP flood event)
FLDLVL_DFE (Designated flood event)
FLDLVL_200 (1 in 200 (0.5%) AEP flood event)
FLDLVL_500 (1 in 500 (0.2%) AEP flood event) FLDLVL_MCC (Maximum channel capacity)
FLDLVL_PMF (Probable maximum flood event)
Note: To see the full scope of the floodplain mapping, 12 dataset layers are required to be loaded in the following order:

Description: The Department of Water produces floodplain mapping of rivers and major watercourses and provides floodplain development advice to ensure that proposed floodplain development has adequate flood protection and does not impact on the existing flood regime of the area.
This advice is related to major river flooding only. Other issues, such as stormwater drainage and envirionmental and ecological considerations are not addressed. Both the floodway and flood fringe make up the 1 in 100 (1%) annual exceedence probability (AEP) floodplain, however there are areas where the floodplain exists but the floodway and flood fringe does not. In such situations, a different floodplain management strategy applies (for example, the Swan River between the Narrows and Canning Bridges).
This dataset contains four lines - Floodway limit, Extent of 1 in 100 (1%) AEP flooding, Extent of floodway & Extent of study. The Floodway limit, Extent of floodway and Extent of 1 in 100 (1%) AEP Flooding and Extent of study line types are boundaries which appropriately overlay over the "FPM 1 in 100 (1%) AEP Floodway and Flood Fringe Areas" (polygon) dataset.

This dataset comprises two polygons - Flood fringe, and Floodway. The flood fringe is that part of the floodplain where development may be considered acceptable subject to certain building conditions that will provide adequate flood protection. The floodway is that part of the 1 in 100 (1%) AEP floodplain where development that is considered obstructive to major flows is not acceptable as it would increase flood levels upstream. No new buildings are acceptable in the floodway.

Name: Urban Water Management Strategies and Plans (DWER-043)
Display Field: plan_name
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: 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 formally known as Urban Water Management Strategies and Plans (DOW-031)

Description: This dataset identifies the Management Areas declared under the Waterways Conservation Act 1976.
Under the Waterways Conservation Act 1976, the Minister for Water and the Department of Water and Environmental Regulation have responsibility for the conservation of the waters and associated land in five declared Management Areas. The declared Management Areas are Albany waterways, Avon River, Wilson Inlet, Peel Inlet and Leschenault Inlet.
The Department of Water and Environmental Regulation has an approval process for certain works affecting waterways and foreshore areas and can provide advice on other developments affecting, or likely to affect, the condition and public amenity of these waterways.
Key aspects of the Act relate to protecting and managing the condition and amenity of waterways when there are disturbance activities within or adjacent to the Management Areas. Activities within or adjacent to the Management Area that should be referred to the Department of Water and Environmental Regulation for discussion or licensing include:
* changes or intensification of land use adjacent to or impacting on waterways or their foreshore areas (e.g. land planning, development, mining, mineral exploration, drainage or flood risk management proposals)
* dredging, reclamation, dewatering, drainage and construction activities including retaining walls, jetties, private boat ramps or public facilities
* other activities that may affect declared management areas, for example, those that may increase nutrients.
Further information and advice can be sought from Department of Water and Environmental Regulation's regional offices. Contact information for regional offices is available at the Department of Water website.

Description: Surface Water subareas stored in WRIMS (Water Resource Information Management System). Surface Water Allocation Subareas for Western Australia were derived in consultation with the regional offices,
and geometry is based on hydrographic catchments. Regional Department of Water and Environmental Regulation 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. Allocation 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.

Description: Purpose: Management of Groundwater resources in Western Australia.
Groundwater Resources stored in WRIMS (Water Resource Information Management System). The intersection of groundwater Subareas with Aquifer boundaries (usually) define groundwater Resources, which are the units used by the DWER to manage environmentally sustainable limits of extraction for groundwater resources.
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. These groundwater areas are
further subdivided into groundwater subareas. The subareas are not proclaimed under the Rights in Water
and Irrigation Act, but are administrative boundaries used to manage the extraction and licensing of groundwater resources.
Groundwater Resources in this dataset are not always the intersection of a Subarea with an Aquifer. Additionally, the Groundwater Areas stored in WRIMS do not accurately reflect the official gazetted Groundwater Area boundaries. A program is currently underway (Sept 2005) to review both Groundwater Resource and Groundwater area boundaries. Please contact the data steward for more information.
