This dataset is a collation of data, including aquifer properties and test design, from pumping tests conducted in Victoria. This data was initially compiled as part of the Secure Allocation Future Entitlements (SAFE) project and updated in the aquifer properties project with the Department of Economic Development, Jobs, Transport and Resources.

Wetland landscape profiles represent a regionalisation of wetlands at the landscape scale. They are based on variation in regional wetland vegetation as described in Appendix 3 of Department of Sustainability and Environment (2012) Index of Wetland Condition assessment of wetland vegetation update - December 2012. Department of Sustainability and Environment, East Melbourne, Victoria.

This dataset consists of 'modified' and 'unmodified' waterways for Victoria which have been attributed as 'perennial' or 'non-perennial' (i.e. ephemeral).

This layer contains the line and polygon features depicting the outline of Victoria and major waterbodies at 1:500,000. The linework was derived from the VICMAP 1983 Digital map of Victoria.

SKM TO PROVIDE

Sustainable Diversion Limits (SDL) have been developed across Victoria and represent the upper limit on winterfall diversions, beyond which there is an unacceptable risk that additional extractions may degrade the environment. Combined with the volume of current extractions the SDL provides water managers with volume of available water in catchments across Victoria.

This layer contains the yearly standard outputs reported to DELWP by CMAs. The raw submissions have gone through a statewide consolidation process which QAs selected common attributes.

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.

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.

Areas of catchments that drain directly to Victorian estuaries - i.e. not via major freshwater tributaries. The layer was derived by Deakin University as part of the project: "Linking catchments to the sea: Understanding how human activities impact on Victorian estuaries" funded by the National Heritage Trust and the Department of Sustainability and Environment.
