The Water Act, 1989, requires that anoyone wishing to extract groundwater must apply for a groundwater licence. Groundwater licences are issued to protect the rights of licence holders, ensure that water is shared amongst users and to ensure that environmental requirements are protected. This dataset is derived from the Victorian Water Register.

Hydrographs from over 2000 state observation bores were reviewed in order to group bores which have a similar water level trend and are screened in the same aquifer. The groupings of observation bores are referred to as 'suites' and are classified according to the Upper, Middle, Lower and Basement aquifers aligning with the Victorian Aquifer Framework. By applying a statistical technical, a normalised hydrograph was developed for each suite using the observed water levels from all bores within the suite. This hydrograph is representative of the groundwater trend within the suite. A spatial boundary has been created for each suite which encompasses all bores within the suite. The boundaries were manually constructed and cover the extent of the mapped aquifers.

This dataset is a subset of the Victorian Groundwater Data Inventory, developed by DELWP. The Data Inventory collated available data relating to four themes: groundwater recharge, aquifer/aquitard properties, groundwater use and aquifer/aquitard thickness. Information has been sourced from 65 hydrogeological studies and contains a spatially enabled representation of data coverage. This dataset represent the Aquifer Properties component of the Data Inventory.

This dataset comprises publicly available data derived from the Victorian Water Register.

This layer is to be used in conjunction with the WSPA layer. It represents individual zones within a specific Water Supply Protection Area.

The Index of Wetland Condition (IWC) is a standard method developed in Victoria for rapid assessment of wetland condition. It is based on the state of the biological, physical and chemical components of the wetland ecosystem and their interactions. The method aims to differentiate natural from human induced changes in wetland condition and assist in management decisions. It has six weighted sub-indices based on the characteristics that define wetlands: wetland catchment; physical form; hydrology; soils; water properties; and biota. It is primarily a site/habitat based assessment (individual wetland scale), some measures require wetland catchment scale assessment. This data set contains the results of 389 IWC assessments conducted between January 2009 and April 2011 to provide a snapshot of the condition of Victoria's wetlands.

Victorian Water Asset Database (VWAD), contains the identification of water assets and their attributes for the state of Victoria. The VWAD includes features such as lakes, rivers, creeks, wetlands, water storages, estuaries, groundwater aquifers, springs, large marine intertidal zones, but does not include specific irrigation and water supply infrastructure such as irrigation channels, bores and irrigation distribution networks.

The groundwater resource along the South Australian-Victorian border is shared between the states. In recognition of the need to cooperatively manage these resources, the two states entered into the Border Groundwaters Agreement in 1985. This agreement establishes a Designated Area, extending 20 km on either side of the border, and from the coast to the Murray River.

The Data Inventory collated available data relating to four themes: groundwater recharge, aquifer/aquitard properties, groundwater use and aquifer/aquitard thickness. Information has been sourced from 65 hydrogeological studies and contains a spatially enabled representation of data coverage. This dataset represent the Recharge component of the Data Inventory. A total of 35 groundwater recharge data sources were identified for Victoria and 31 were successfully sourced and added to the database.
