This dataset representst Victoria’s Groundwater Management Areas (GMAs) Where groundwater has been intensively developed in Victoria, or has the potential to be developed, Groundwater Management Areas (GMAs) are established and the Permissible Consumptive Volume (PCV) is progressively set. Monitoring of the groundwater resource in these areas is undertaken by the Department of Sustainability and Environment through the State Groundwater Monitoring Network. Water levels and the amount of water allocated to groundwater users in the areas are closely monitored.

This geodatabase contains groundwater data as scheduled under the Environmental Protection (Water and Wetland Biodiversity) Policy 2019.

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)

Current ACT Water Management Areas. Water Resources (water Management Areas) Determination 007 (No1). This data defines the boundaries of catchments used for management of ACT Water Resources. The areas help determine how much water is available for use at a particular location. Last updated December 2013.

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)

Surface Water - This dataset displays Victoria's surface-water Water Supply Protection Areas (WSPAs), and has been prepared for the Groundwater and Licensing Branch and the River Health Branch DSE, by LICS (Land Information Cartographic Services) and Melbourne Water. As part of the 2002 amendments to the Water Act 1989, surface-water was included to allow WSPAs to be declared for the protection of surface-water resources in a defined area. A legally enforceable Streamflow Management Plan is then developed. The aim of the plan is to manage the surface water resources of the WSPA equitably and to ensure the long-term sustainability of the resource. An extensive consultative process guarantees that surface water users have a major input into the development of the Streamflow Management Plan for their area. A Ministerial appointed Consultative Committee which represents all relevant interests prepares the Plan. In an area where farming predominates, farmers who own or occupy farming land in the area must comprise at least half of the membership of the committee. Groundwater - This dataset displays Victoria's groundwater Water Supply Protection Areas (WSPAs), and was originally prepared for Groundwater and Licensing Branch DSE, by LICS (Land Information Cartographic Services). Boundaries generaterd by LICS and Melbourne Water. Subsequent revisions have been undertaken by GLiB and the Rural Water Corporations. WSPAs are areas that have been (or are proposed to be) proclaimed under the Water Act 1989 for the purpose of establishing a management plan.
