Bore locations in the Bay of Plenty Region.

Database storing registered water bore data from private water bores and Queensland Government groundwater investigation and monitoring bores. Data includes bore location, water levels, construction details, strata log, and water quality.

This series comprises a catalogue of groundwater observation bores produced by the Groundwater Section of the Department of Industry, Technology and Resources (VA 2661) in 1988.

The Department was responsible under the Groundwater Act (1969) for the exploration, investigation and evaluation of the State’s groundwater resources, and established an extensive network of observation bores throughout Victoria for monitoring purposes.

This catalogue includes bore identification descriptions and the construction details of all groundwater observation bores completed prior to the end of 1985. Also recorded is the quality of the groundwater, with hydrographs showing water level fluctuations over time. The frequency of monitoring ranged from continuous to quarterly, with the most common frequency being monthly. The observation bores are predominantly located in the five major Tertiary sedimentary basins – the Murray, Otway, Port Phillip, Westernport, and Gippsland basins. Each volume refers to bores drilled in three broad geographical regions of Victoria: ‘Southeast Victoria’, ‘South West Victoria’, and ‘Northern Victoria’.

The first comprehensive groundwater bore database was assembled in the late 1960s by the Geological Survey of Victoria (VA 4118). Prior to the mid-1980s, all bore locations were plotted on map sheets and records kept in hard copy only. A digital database compiled from these existing records of all Government and private bores was progressively assembled from the mid-1980s onwards. This catalogue was the first compilation of information on Victoria’s groundwater bores, compiled from numerous data banks held by the Department at the time and contributed to by professional, technical, and drilling staff.

Each observation bore has a unique identification comprised of parish name and sequential bore number within that parish. Each parish is also numbered according to its position in the alphabetical listing of all parishes within the State (as of 1985).

Bores within each parish are differentiated according to drilling authority. Bore numbers between 1 and 7999 were drilled by government agencies, mainly the Department of Industry, Technology and Resources (DITR), State Electricity Commission of Victoria (SECV) or Rural Water Corporation (RWC). Bores in the range 8000 to 9999 refer to private bores drilled outside the jurisdiction of the Groundwater Act (1969) and bores numbered 10000 or greater are water bores drilled under the controls of the Groundwater Act (1969).

Bores drilled by DITR are given a consecutive number as a temporary identification. These numbers have three components, namely DITR drilling rig number, year drilled, and sequential number of bores drilled in that year by that particular rig. Bores given the consecutive number 99/99/999 were drilled by private contractors for government agencies.

Bore locations are provided as a map reference using the Standard Australian Metric Grid (AMG) co-ordinate system. Information provided includes AMG Zone and Co-ordinates (easting and northing) together with the 1:100 000 Map Sheet reference. The elevation of the land surface at bore sites is given relative to the Australian Height Datum (AHD), i.e., the reduced level of the natural surface, given as meters AHD.

The National Groundwater Information System(NGIS) contains more than 800 000 bore locations with associated lithology logs, bore construction logs and hydrostratigraphy logs. 2D and 3D aquifer geometries are also available for some areas.

The NGIS is a geodatabase for storing nationally consistent groundwater data based on the ArcHydro for Groundwater data model. Contents include: -bores -bore (hydrostratigraphy) logs -construction logs -lithology logs -hydrogeologic units -3D bore (hydrostratigraphy) lines -3D construction lines -3D georasters -3D geovolumes

NGIS Version 1.2 uses the NGIS Version 2.3.1 data model, a minor revision of which was released in April 2015.

The Bureau of Meteorology maintains the NGIS data model that standardises and spatially-enables the groundwater data.

The lead water agencies in each State/Territory (plus Water Corporation in Western Australia) export data from their corporate groundwater databases into State/Territory NGIS geodatabases including:

~~~~~~~~~~~~~~ DATA ACCESS ~~~~~~~~~~~~~~~~ The entire NGIS geodatabase can be requested by email. Parts of the database can be downloaded from the Australian Groundwater Explorer.

Bores and bore log information from the System can be accessed and visualised using the Australian Groundwater Explorer, without using desktop GIS software. The Explorer also includes data not contained in the National Groundwater Information System, such as groundwater level time-series data. Landscape characteristic spatial layers, such as groundwater management areas and river regions can also be displayed to provide context to the groundwater data.

"Australian Groundwater Explorer" webmap url: http://www.bom.gov.au/water/groundwater/explorer/map.shtml
allows all data, per state, to be downloaded [use top icon near righthandside], or data by selected area (see the Groundwater Explorer's HELP link]. Data search can be filtered by status, purpose, agency, river region, sedimentary basin, or a drawn area. A plaintext version of the "Groundwater Explorer" [ http://www.bom.gov.au/water/groundwater/explorer/simple-location.php ] allows the search to be filtered by placename or lat/long, and a radius.

Abstract

This dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied. Metadata was not provided and has been compiled by the Bioregional Assessment Programme based on known details at the time of acquisition.

This dataset consists of a set of spreadsheets and pdf documents containing raw water level data for bores pertaining to mines within the Galilee Basin; Alpha, Carmichael and Kevins Corner. Data is provided by QLD DNRM.

Data includes:

A spreadsheet with bore details for some of the private Clematis bores.

A map showing rough contours drawn using the above data. Estimated groundwater elevations are just assigned using google earth. The green line represents the approximate eastern boundary of the Clematis outcrop/ subcrop and the purple line the very approximate eastern boundary of the Ronlow Beds subcrop. The groundwater database registered numbers are plotted on the map with the estimated groundwater head elevations in brackets, water level data that has been provided by URS on behalf of Adani, Carcmichael and Alpha. Water levels are below the top of casing. A negative water level represents subartesian conditions. Where the water level is positive it is above casing.

Abstract

The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

The aim of deriving this dataset was to be able to estimate groundwater quality and location of each groundwater bore with respect to the water source area in the Gloucester subregion. An estimation of groundwater salinity is made based on the total dissolved solids (TDS) values reported in the original data sets provided by the NSW Office of Water. This has been clipped to the Gloucester subregion.

A spatial dataset (point shapefile GLO_Bore_extractions.shp) has been derived from this data for report map purposes. Also the point TDS values have been interpolated into surfaces (separate Aquifer and Fractured Rock).

These spatial data derivations are also included in the dataset.

Dataset History

Bore locations in the Gloucester NGIS Bores database that were spatially located withing the Gloucester subregion boundary were extracted and filed.

Bores with groundwater quality in the NSW Office of Water Groundwater Quality extract 28_nov_2013 database that were spatially located withing the Gloucester subregion boundary were extracted and filed.

Based on the salinity/electrical conductivity values reported in the NSW Office of Water Groundwater Quality extract 28_nov_2013 database, total dissolved solids values were estimated and filed.

Bore were classified as "alluvium" and "fractured rock" based on depth of the bore from the surface as reported in the Gloucester NGIS Bores database. Bore with a depth less than 15 m and between 15m to 150 m were classified as alluvium and fractured rock bores respectively.

Bore points were separated into "alluvium" and "fractured rock" and their TDS values interpolated (ArcGIS TOPOGRID Spline) into two respective TDS surfaces. Surface extent was constrained to an arbitrary envelope around the data points. The interpolation bounding polygons are also included in this dataset as shapefiles.

River, stream, dam and bore data displayed on a map.

A hydrogeological map-set of the Lake Amadeus-Ayers Rock region in central Australia has been prepared as a pilot project for a national groundwater resources inventory. The maps in the set were compiled on a computer graphics system at 1:250000 scale from layers representing topography, bedrock geology, surficial geology, hydrodynamics, hydrochemistry, and water-bore locations. The quantitative information was obtained from a microcomputer database, and the geological and topographic information was digitised from specially revised maps. As the hydrogeological data are sparse it was decided to publish the main maps at 1:500000 scale. For three areas where more detailed information was available, inset maps at 1:100000 scale are presented. The region mapped is arid; annual rainfall is about 250 mm and potential evaporation close to 3000 mm. Groundwater recharge is of the order of I mm/year. Important aquifers are surficial Cainozoic sand and calcrete, and bedrock sandstone units including the Palaeozoic Pacoota Sandstone and Mereenie Sandstone. Groundwater varies in quality from 0.4 g/L to more than 200 g/L total dissolved solids. Groundwater converges from the north and south towards a southeast-trending chain of playas, where it discharges by evaporation. Hydrochemical evolution is apparent along groundwater flow paths. Fresher water, generally bicarbonate-rich, occurs close to the hilly recharge areas and in the calcrete. This evolves to highly saline chloride-rich brines in the playas, by processes of solution, precipitation of minerals, and evaporative concentration. Groundwater supplies have been developed for the Yulara tourist resort, the largest settlement in the area, although the water, derived from Cainozoic sands, is desalinated for use in domestic supplies. For a proposed tourist resort at Kings Canyon, a water supply is being developed from bedrock units, mainly the Pacoota Sandstone. Single bores are scattered through the region, supplying cattle stations and Aboriginal settlements. In this hydrogeologically complex region, extrapolation from conceptually known areas is difficult. The detailed assessment of ground water resources will require additional drilling.

The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

This resource contains raster datasets created using ArcGIS to analyse groundwater levels in the Namoi subregion.

Purpose

These data layers were created in ArcGIS as part of the analysis to investigate surface water - groundwater connectivity in the Namoi subregion. The data layers provide several of the figures presented in the Namoi 2.1.5 Surface water - groundwater interactions report.

Dataset History

Extracted points inside Namoi subregion boundary. Converted bore and pipe values to Hydrocode format, changed heading of 'Value' column to 'Waterlevel' and removed unnecessary columns then joined to Updated_NSW_GroundWaterLevel_data_analysis_v01\NGIS_NSW_Bore_Join_Hydmeas_unique_bores.shp clipped to only include those bores within the Namoi subregion.

Selected only those bores with sample dates between >=26/4/2012 and <31/7/2012. Then removed 4 gauges due to anomalous ref_pt_height values or WaterElev values higher than Land_Elev values.

Then added new columns of calculations:

WaterElev = TsRefElev - Water_Leve

DepthWater = WaterElev - Ref_pt_height

Ref_pt_height = TsRefElev - LandElev

Alternatively - Selected only those bores with sample dates between >=1/5/2006 and <1/7/2006

2012_Wat_Elev - This raster was created by interpolating Water_Elev field points from HydmeasJune2012_only.shp, using Spatial Analyst - Topo to Raster tool. And using the alluvium boundary (NAM_113_Aquifer1_NamoiAlluviums.shp) as a boundary input source.

12_dw_olp_enf - Select out only those bores that are in both source files.

Then using depthwater in Topo to Raster, with alluvium as the boundary, ENFORCE field chosen, and using only those bores present in 2012 and 2006 dataset.

2012dw1km_alu - Clipped the 'watercourselines' layer to the Namoi Subregion, then selected 'Major' water courses only. Then used the Geoprocessing 'Buffer' tool to create a polygon delineating an area 1km around all the major streams in the Namoi subregion.

selected points from HydmeasJune2012_only.shp that were within 1km of features the WatercourseLines then used the selected points and the 1km buffer around the major water courses and the Topo to Raster tool in Spatial analyst to create the raster.

Then used the alluvium boundary to truncate the raster, to limit to the area of interest.

12_minus_06 - Select out bores from the 2006 dataset that are also in the 2012 dataset. Then create a raster using depth_water in topo to raster, with ENFORCE field chosen to remove sinks, and alluvium as boundary. Then, using Map Algebra - Raster Calculator, subtract the raster just created from 12_dw_olp_enf

This series contains a number of different registers and indexes regarding the management of bores and boring activity by the Geological Survey of Victoria (GSV) (VA 4118). While subject to further research, the registers are thought to have been created during a period when borehole numbering systems were being updated and moving to an electronic management system.

From the 1880s to 1990s, a bore was identified by the Parish in which it was drilled followed by a sequential number. As some earlier bores were identified by a project name and due to changes in parish boundaries, some early bores were subsequently renumbered to match that system.

The bore numbering changed again with the introduction of electronic databases in the mid-1980s. At this time, bore numbers became encoded as a 10-digit bore number, comprised of single digit for the State (Victoria = 3), the four-digit Parish code, and a five-digit sequential number within each parish. The series of bores numbered 08000 to 09999 (referred to as 8000 series bores) were private groundwater bores drilled before the Groundwater Act 1969, and the bores numbered 10000 to 14999 (the 10000 series bores) were private groundwater bores drilled after the Groundwater Act 1969.

The register Boreholes in Selected Parishes, Generation 65 (09/09/1989) is a register of bores by parish and lists parish name and number, bore number, owner (e.g. ‘Private’, ‘Government department’, ‘Company’), AMG map reference/coordinates, coordinates method (e.g. ‘Scaled’, ‘digit’, ‘survey’), completed date, bore depth, bore-use (e.g. ‘Groundwater’, ‘Unknown’, Water-ABN, Water-Stock’) and drill method (e.g. Cable, Rotary).

The registers Summary of Geophysical Logs Held by GSV Geophysics Section and Index of Electric Logs list bore, parish, date run, company, log type and information available, quality and number of logs.

The register Index of Government Bore Numbers lists the first to last number (bore ID) and parish, the specific reference (e.g. ‘D arill 7 1974 (7/74/2)), authority (e.g. Government agency) and year drilled.

The register Core Data is a guide to physical bore samples and lists bore number, construction number, interval from-to, type of sample (e.g. cutting, core), bay, row, tray (possibly location of sample at GSV Drill Core Library) and local bore name (e.g. c/5337, or locality).

The registers 8000 Series Register and 10 000 Series Register list parish, bore number, property owner, drilling contractor, military sheet (map reference), descriptive location, bore identification (e.g. ‘EL 663 CD 01’), bore usage (e.g. Water, brown coal) and completed date.

The register Aquifer and Pump Test Descriptions lists parish name and number, bore number, lithology, casing, screened interval, pump, pump test rate/time draw down and test date.

The register Composite of Water Quality and Aquifer Details - Latest Analysis Only Per Bore lists, aquifer description, date of drill, lithology, pump details, latest chemical analysis of water and sample,

The register Chemical File Listing lists parish name and number, sample type and method for determination etc.

DEPI originally engaged GHD to develop seamless 3D aquifer surfaces for the Victorian Aquifer Framework (VAF). The seamless mapping of aquifers across the state provides the fundamental framework for groundwater resource management, underpins development of a revised management structure for Victoria (the Secure Allocation Future Entitlement project funded by the National Water Commission) and contributes to the data needs of the Bureau of Meteorology National Groundwater Information System (NGIS). The original dataset was produced by GHD in 2012 using (in part) data provided by Southern Rural Water Corporation and Goulburn-Murray Water Corporation. It has been subsequently amended by Hocking et al and SKM in 2013. Dataset History A number of key input datasets were sourced as part of the process to derive the 3D aquifer surfaces. These datasets included: The DEPI State-wide Stratigraphic Database (SSD); The National Groundwater Information System (NGIS) database containing groundwater borehole location information as well as lithological and stratigraphic information; Raster layers previously produced for Southern Rural Water (SRW) by SKM and GHD in 2009; The crystalline basement surface provided by the former Department of Primary Industries (DPI); Outcrop 1:250,000 scale geological mapping compiled by the former Geological Survey of Victoria, DPI; A state-wide 100m Digital Elevation Model (DEM) based on the DEPI 20m DEM. This was used to represent the natural surface; Data generated using DEPI's state-wide ecoMarkets groundwater modelling package to assist with the definition of key layers of the major Cainozoic aquifers; Latrobe Valley Coal Model which was used to provide a framework for the hydro-stratigraphy of the wet Gippsland Basin; Rasters of the top elevation of the major aquifer systems covering the Kiewa, Ovens, Goulburn-Broken and Loddon and Campaspe catchments; Data extracted from the Basin in a Box, the Murray Basin Hydrological Map Series and the Murray-Darling Basin Groundwater Status 1990-2000: Summary Report; Airborne magnetic data publicly available from raster data published by the former Geological Survey of Victoria, DPI. Once the input data had been compiled, the VAF 3D surfaces were developed by lfollowing a number of key steps, summarised below: (1) Contours as polylines and aquifer extents as polygons were extracted from previous mapping surfaces; (2) Outcrop points attributed with values from the DEM were created; (3) Based on the state-wide stratigraphic database, the contours and extents were refined or created; (4) A top elevation raster was interpolated using contours, outcrop points and bore data then replacing outcrop areas with the DEM; (5) The aquifer thickness was then checked in GIS by comparing layers against each other and assessing for cross-overs and negative thickness; (6) The input data was then revised and bore data, contours, and aquifer extents modified as required due to errors in the thickness; (7) If there were subsequent issues identified such as overlaps between aquifers, mismatches between bores and resulting layers, then the process was revised by returning to Step (3); (8) If the layers were matching well, then extent points were created to smooth layers at the edges; (9) A top elevation raster was generated again using contours, outcrop points, extent points and bore data; (10) The aquifer thickness was checked again, and if significant issues were identified, then the process returned back to Step (3) for further iteration; (11) Further modifications were applied to remove negative thicknesses and to provide minimum thickness of overburden; (12) Top and bottom elevation rasters were then generated at 100m pixel resolution to form the final dataset. In generating each of the layers, a number of Quality Assurance (QA) measures were implemented at various stages of the process. These included a topologic review, a hydrogeological review and an external reveiw by Spatial Vision. The original dataset was published in May 2012 and subsequent revisions have been conducted by Hocking et al and SKM in 2013.

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

The extent of JK Aquifer SANT shapefile is one of a number of data files developed as part of the Australian Government funded research program entitled â Allocating Water and Maintaining Springs in the GABâ .

Purpose

The JK Aquifer in this instance represent all rocks interpreted and mapped as the stratigraphic units the Cadna-owie Formation (Knc) and the Algebuckina Sandstone (JK-a) as well as units mapped as a potentially being one of these formations (JK1).

Dataset History

Digital copies of seismic lines, around the western margins of the Eromanga Basin, were loaded into a Geoquest workstation for interpretation. Due to the sparcity of lines, lack of suitable ties and large distances between data sets, picks were mostly done by eye. These picks are simple and can be considered correct in the broad sense. Converting the two way time data from the Geoquest interpretation proved too erratic to be useful. Seismic time data was imported from Geoquest to Petrosys mapping system. In Petrosys, bore tops and outcrop elevations were gridded and contoured. The resulting contour maps were examined for realism and consistency and anomalous tops and areas were reviewed. This was an ongoing process. Geological trends from the seismic were incorporated, also known and inferred fault planes. An extensive series of edits and checks was undertaken until a satisfactory geological map was accomplished. That is, the contours were geologically reasonable, matched all bore and other tie points, followed trends from seismic and merged with previous data based mapping logically and smoothly.

Abstract The dataset was compiled by the Geological and Bioregional Assessment Program from multiple sources referenced within the dataset and/or metadata. The processes undertaken to compile this dataset are described in the History field in this metadata statement. The dataset was developed to assist in the classification of permanent waterholes in the Cooper GBA region. ## Attribution Geological and Bioregional Assessment Program ## History The dataset contains two shapefiles. The first (COO_Lakes_WH_WFS.shp) contains all the lakes and waterholes identified in the 250K topo maps and uses the Water Observations From Space dataset to find the pixel within each polygon that has the maximum proportion of time inundated (MAX field). Waterholes that are inundated more than 70% of the time (MAX>0.70) are considered to be semi-permanent, those that are inundated more than 95% (MAX>0.95) are considered to be permanent. The second dataset (perm_WH_DTWT.shp) is looking at the depth to water table beneath waterholes. There are no dedicated observation bore networks to look at groundwater levels beneath waterholes so this dataset is using the closest water level observation up to a maximum of 5 km away. The field NEAR_DIST is the distance of the bore from the waterhole and the field WH_DTWT is the depth to water table below the waterhole assuming that the groundwater level is the same as that in the borehole within 5 km. A positive value in WH_DTWT means that the groundwater level is below the water level of the waterhole, a negative value means that the groundwater level is above the water level of the water hole.
