The groundwater resource zones include the Berry Springs Water Allocation Plan area. The zones have been delineated using the methodology described in Water Resources Division Technical Report (20/2023) Groundwater management zones in the Darwin Rural (Tickell et al., 2023). The report can be accessed here: https://territorystories.nt.gov.au/10070/980415. The dataset was used to develop an Estimated Level of Use for each groundwater zone.

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. 7 February 2025. Darwin Rural Water Control District: The number of groundwater resource zones was further reduced to 12 consolidated areas within the Darwin Rural Water Control District. The data compilation process is described in the report, Tickell et al., 2023. The process to establish the estimated level of use for each zone was completed using the methodology described in Water Resources Division Technical Report (2/2021) Status of groundwater resources in the Darwin Rural Water Control District and Palmerston Municipality (Miles, 2020).
