This layer contains points locating groundwater research bores statewide. It documents data concerning bores drilled mostly to allow access to groundwater to support various uses and groundwater monitoring and research. The information within this layer derives from the PIRVic Bendigo Groundwater Database currently stored in SQL. This layer has been supereceded by DW_POINTS

Groundwater Flow Systems (GFS) have been developed in the National Land and Water Resources Audit as a framework for dryland salinity management in Australia. Originally developed in a broad national context, GFS has since been applied at the Murray Darling Basin scale and consequently CMA scale to support and underpin the development of salinity management strategies across regional jurisdictions. GFS1M joins and aggregates the mapping for the Victorian CMAs where a GFS framework exists, and presents a statewide map with a consistent attribute framework. Of the order of 100 regional GFSs is condensed into 25 statewide GFSs. GMS1M is designed for broad statewide policy use only. The GFS framework encompasses: (a) identification of generalised conceptual models of groundwater behaviour in each of the region's geological and geomorphic provinces, (b) an assessment of the physical attributes of each system, and (c) first order consideration of potential salinity management strategies applicable within each GFS. A GFS will exhibit similar physical characteristics across its extent, and generally incorporate the complete groundwater flow path from recharge to discharge. Central to the framework is the assessment of the hydrogeological responsiveness of a GFS that guides appropriate land use to assist in the management of salinity. The development GFS framework for a region is typically undertaken through intense workshopping involving local expertise, then this documented in a regional GFS map and accompanying report. The consolidation of regional GFSs into GFS1M was undertaken by PIRVic and funded through NAP.

The dataset is a subset of Minerals and Petroleum's BORES dataset and contains geological data from Minerals and Petroleum's boreholes RDBMS. The dataset contains any borehole records which have lithological, stratigraphic or assay data as well as any borehole records where the purpose was recorded as being minerals-related.

This is a subset of Minerals and Petroleum's Boreholes database - that only includes boreholes that have temperature records. The majority of the data was collected for a particular Geothermal project that concluded in late 2007. The detailed data about these observations (including correction info) are not available within the dataset itself. For further information and an excel copy of the full data, refer to VIMP report 85 - appendix 2 and an excel attachment.

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.

Contains mineral, petroleum, coal & groundwater boreholes. Minerals boreholes (and, to a lesser extent, petroleum wells) are actively maintained in the dataset. The custodial role for groundwater and coal boreholes is in the private sector, and these parts of the dataset are not actively maintained. Mineral, petroleum and coal boreholes are updated on an irregular basis: Mineral borehole data are supplied by individual companies usually when their overlaying Exploration Licence expires; Coal borehole data have been updated from GHD Pty Ltd's (formerly GEO-ENG) data. Groundwater boreholes have not been updated since 1990 when the custodial role was given to Sinclair Knight Merz Pty Ltd (SKM) - refer to BORES100. The origin of data varies considerably. Prior to 1980 borehole data was recorded by the Geological Survey of Victoria (GSV) on 1 inch:1 mile plans and hard-copy borehole records. This included data for water boreholes drilled by public and private sector, all boreholes drilled by GSV, petroleum wells, and some private-sector mineral exploration boreholes. In areas where drilling was of particularly high density, locations were recorded on these plans as a single point or as occurring within an outlined area. The parish was traditionally used as the primary classifier for numbering boreholes. Some minor anomalies exist where a borehole and parish boundary may be on one side of a road or the other, or where parish boundaries have been moved. In 1980 the location data was moved to 1:100,000 AMG plans. In the mid-1980s a program of electronic capture commenced. Borehole locations were digitised from the 1:100,000 plans with an accuracy of +/-300m. For the areas of high borehole density where boreholes were plotted on a single point, often only the first ten and last ten were recorded in the database. Boreholes whose parish was known but exact location was unknown were also recorded, but do not have a location. Groundwater boreholes: Extensive hydrological data was originally held by GSV, but these data are now held by SKM. Coal boreholes: Location and lithological data for coal boreholes has been provided by Geo-Eng and the old State Electricity Commission of Victoria. Mineral exploration boreholes: The capture of mineral exploration borehole data from open-file exploration reports commenced in 2001 and will progressively cover the state over a number of years. The data are being captured at an whatever accuracy the source allows, typically between 20 and 250 m. Assay data have been consistently captured. Other downhole data, such as lithology, have not been consistently captured. Tenement information for the small number of private-sector mineral exploration boreholes captured prior to 2001 was lost in the migration from the original VAX database to the current Ingres corporate database. Heavy mineral sand exploration: complete coverage up for data up to April 2002; updates planned for late 2003. Other mineral exploration: coverage as follows - St Arnaud, Charlton, Wedderburn 1:100 000 mapsheets - 31 March, 2001; Dunolly, Rupanyup, Donald, Ararat, Grampians, Willaura 1:100 000 mapsheets - 30 August 2001; Warburton 1:250 000 mapsheet - 30 June 2002 (available mid-2003); Ballarat, Creswick, Skipton, Beaufort 1:100 000 mapsheets - 30 June 2002 (available mid-2003); Bendigo 1:250 000 - 31 October 2002 (available mid-2003) Groundwater data can be obtained at the following site http://www.dse.vic.gov.au/waterdata

This layer represents the spatial extent, species distrubtion and density of seagrass meadows within the Gippsland Lakes. This layer is a result of a baseline survey of seagrass within the Gippsland Lakes. Ecological research into the health of seagrass meadows requires the type of detailed information collected in this baseline survey. This information will be used to establish future monitoring programs and it is envisaged that these areas will be re-surveyed every 5 years to detect macro changes.

This layer presents the spatial extent, species distribution and density of seagrass/submerged aquatic vegetation at Gippsland Lakes mapped from 1997 aerial photography and field observations.

This dataset contains primary geological data, namely Pre-Permian geological rock units and boundary types separating rock units. The linear features in this dataset are only comprised of geological boundaries and faults. The data has been collected by the Geological Survey of Victoria. This dataset is accompanied by another dataset representing metamorphism. The pre-Permian geology data from Simons and Moore (1999) shows the interpreted geology of Victoria, with the Permian and younger units stripped off. It was compiled from the surface geology map and interpretation of the extensive new magnetic, radiometric and gravity data along with seismic profiles where available. It attempts to reconcile the mapped geology with the geophysical data sets, to produce a map that is both geologically and geophysically reasonable. The data should be used in combination with the state magnetic image as this image gives extra information that could not be adequately presented on the map, such as sedimentary or contact-metamorphic changes in the magnetic properties of rock packages, dyke swarms, and thick basalt cover. The legend subdivides the rocks by time and palaeoenvironment or geochemistry, which gives a complementary view of the geology to that of the surface Australian crust during Phanerozoic orogenic events. Granites were subdivided using White and Chappell's (1983) S, I and A classification, as this is a subdivision that is both generally understood and works well with the magnetic data. The time subdivisions are at the natural breaks in the Victorian geological record, usually the ends of orogenies. This has meant that all the intrusions associated with a particular event are grouped in the same time slice, even when some could perhaps be allocated to a younger time slice.
