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.

Winterfill sustainable diversion limit volumes (SDLs) have been developed across Victoria and represent the upper limit on winterfill diversions, beyond which there is an unacceptable risk that additional extractions may degrade the environment. The SDL_BASIN dataset is a spatial representation of river basins, which represent an aggregate of the intermediate SDL catchments. These basins DO NOT reflect the Victorian surface water river basins as defined by the Australian Water Resources Council. Winterfill SDL data is held in the SDL_DATA layer.

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

This layer is part of Vicmap Lite and contains polygon features delineating hydrological features. Vicmap Lite datasets are suited for use between scales of 1: 250,000 and 1 : 5 million. The polygons were sourced from Vicmap Hydro. The level of attribute information, the number of features and the number of vertices has been simplified to suit the 1: 250,000 - 1 : 5 million scale range. The concept of a Scale Use Code has been introduced to help control the level of detail displayed. THIS DATASET WAS LAST UPDATED IN NOVEMBER 2015

This layer represents the stream segments opened to fish movement by the removal of barriers. At this stage the layer only shows passages in the Glenelg-Hopkins and West Gippsland CMA's.

This dataset contains the digitised centroids of smaller man made waterbodies (including farm dams) in northern Victoria using a combination of satellite and aerial imagery. Should be used in conjunction with FARM_DAMS. This data was updated in January 2019 to improve the usefulness of the attribute data.

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.

Regions by which water quality and quantity is monitored.
