  • 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.

  • 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.

  • This layer contains points locating groundwater bores statewide. It documents data concerning bores drilled mostly to allow access to groundwater to support various uses and groundwater monitoring and (salinity) research. This dataset was superceded by a layer called gwbores100 which in turn has been replaced by the dataset DW_POINTS.

  • Regions by which water quality and quantity is monitored.

  • GMU

    This table is used by the Groundwater Resource Reporting Tool. It includes GMAs and WSPAs.

  • Polygons showing the extent of wetlands in Victoria prior to European settlement. Wetlands are classified into primary categories based on water regimes. The polygon boundaries were derived from digitizing marked up aerial photography interpretation.

  • 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 layer is used in association with the GMA layer and represents the internal zone boundaries within each GMA (if applicable).

  • This layer contains points showing the location of water monitoring points, groundwater bores, index of stream condition and marine monitoring sites. The data is sourced from the Victorian Water Resources Data Warehouse

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