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.

The ISC2010_BARE_GROUND polygon features represent the parts of the assessed bank face that do not have vegetation cover. The bank face is defined as the area between the Top and Toe of the bank. Areas of Bare Ground less than 5m2 have been removed so that data volume is manageable. River condition in Victoria is assessed every 5 years using the Index of Stream Condition (ISC). The Department of Environment and Primary Industries (DEPI) developed a methodology to assess the Physical Form and Riparian Vegetation components of the ISC using remote sensing data, specifically LIDAR and aerial photography. A State Wide mapping project was undertaken in 2010-13 to accurately map the Physical Form and Riparian Vegetation metrics of the ISC . Other ISC metrics were not assessed in the project and were derived from other sources. The Physical Form and Riparian Vegetation Metric products are a combination of mapped Vector and Raster data as well as Tabular Summary Statistics about the mapped features. In the context of the project, the term Metrics is used to refer to both the mapped features and the summary statistics. Remote sensing data used includes 15cm true colour and infra-red aerial photography and four return multi-pulse LiDAR data. This source data was used to derive a variety of Raster data sets including Digital Terrain Models, Slope, Vegetation Height and Vegetation Cover. The Digital Terrain and Slope rasters were used to map Physical Form metrics including Stream Bed, Top of Bank and River Centre Lines while the Vegetation Height and Cover rasters were used to map the Riparian Vegetation metrics. The Project Report "Aerial Remote Sensing for Physical Channel Form and Riparian Vegetation Mapping" describes the remote sensing and mapping approach used to create this data set.

LCC_ECC_VEAC_INVESTIGATIONS shows the geographic boundaries of the Land Conservation Council (LCC), Environment Conservation Council (ECC) and Victorian Environmental Assessment Council (VEAC) investigation areas. Statewide extent investigations are not included in the dataset: Statewide Assessment of Public Land Use (1988), Rivers and Streams Special Investigation (1991), Wilderness special investigation (1991), Statewide Assessment of Public Land (2017).

The ISC2010_WATER_BODIES_S table is the Statistical Summary table for the Water Bodies Metric at the 100m Section level. The ISC2010_WATER_BODIES_S table is designed to JOIN to the ISC2010_RIVER_CENTRELINES_S feature class. River condition in Victoria is assessed every 5 years using the Index of Stream Condition (ISC).

The Australian Hydrological Geospatial Fabric Surface Hydrology Catchments dataset was used as the base layer for considering surface water as an asset. This dataset provided mapped major rivers for Victoria. Numerous investigations into the interaction between groundwater and surface water have occurred across Victoria. Where this information was available in a format suitable for use in a GIS, it was collated to inform a state wide dataset of groundwater and surface water interaction. The resulting product attributes the stream base layer (described above) with the following classification of groundwater and surface water interaction: Gaining Variable Neutral/Losing Unclassified
