Title: Groundwater Resource Zones, Darwin Rural Area and Palmerston
Custodian:Department of Environment, Parks and Water Security
This polygon spatial dataset describes 112 groundwater resource zones within the Darwin Rural Water Control District and Palmerston Municipality. The groundwater resource zones include 2 areas that are subject to management through the Berry Springs and Howard Water Allocation Plans. The groundwater resource zones details are current as at 1 December 2020 and subject to change.
The dataset was used to develop an Estimated Level of Use for each groundwater zone. Refer to metadata record www.ntlis.nt.gov.au/metadata/export_data?type=html&metadata_id=B94C369576232508E0530101007FD88B

Lineage:The zone boundaries were derived using ESRI ArcGIS desktop software and are a compilation of several existing datasets;
- Darwin Rural Water Control District, Berry Springs Water Allocation Planning Area, Howard Water Allocation Planning Area, Palmerston locality.
- Aquifers: 1:250k Darwin Groundwater regional mapping, November 2016
- Surface water sub-catchments:
30 August 2017 - A total of 138 groundwater resource zones were created and grouped into 11 groundwater systems. The data compilation process is described in the report, Woltmann 2017, Chapter 7, Assessment methodology.
1 December 2020 - The number of groundwater resource zones were reduced to 112 to consolidate smaller zones within the same groundwater system. The grouping into 11 groundwater systems remain. The process to establish the estimated level of use for each zone was reassessed. The methodology is described in the report, Miles 2020, Appendix A. Refer to supplementary details in this metadata record.
Positional Accuracy:The spatial datasets used to create the groundwater resource zones are varied in scale, ranging from 1:100 000 to 1:250 000.
Attribute Accuracy:Each polygon has been assigned a range of attributes - see Data Dictionary in this metadata record.
Logical Consistency:The spatial data polygons are single part.
01/12/2020 There are 131 single part polygons that make up the 112 groundwater resource zones within the Darwin Rural Water Control District and Palmerston Municipality.
Completeness:The groundwater resource zones are current as at 1 December 2020 and may be subject to change. This metadata record will be updated if any changes occur.
