This layer contains the location of surface water monitoring sites in the Water Measurement Information System (WMIS). WMIS is the primary access point to search, discover, access and download surface water and surface monitoring data collected by DEPI and its partners. More detailed information on individual surface monitoring sites , can be accessed via the WMIS site at http://data.water.vic.gov.au/monitoring.htm.

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.

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 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.

Australian Water Resources Council (AWRC) water basin boundaries and Victorian Government proclaimed water supply catchments. See themes PWSC100 and BASIN100 for more current information.

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

Areas of catchments that drain to points on main tributaries immediately upstream of Victorian estuaries. 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.

Boundaries defining the approximate jurisdiction of the Urban Water Corporations.

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.

Spatial extent of areas in Victoria where the consolidated bedrock is exposed to the surface. This is usually due to geological activity such as faulting or erosion.
