Groundwater data release for the South Nicholson and Georgina Basins, Northern Territory and Queensland

This data package is a key output from the integrated, basin-scale hydrogeological assessment of South Nicholson-Georgina as part of Geoscience Australia’s National Groundwater Systems project in the Exploring for the Future program. This comprehensive desktop study has integrated numerous geoscience and hydrogeological datasets to develop a new whole-of-basin conceptualisation of groundwater flow systems and recharge and discharge processes within the regional unconfined aquifers of the Georgina Basin.

This data release includes an ESRI geodatabase and ESRI shapefiles with associated layer files: -         Georgina Basin watertable trend surface -         Georgina Basin reduced standing water level (RSWL) contours -         Regional scale groundwater divides -         Groundwater flow paths -         Bores with aquifer attribution and water level information where available -         Hydrochemistry data for bores and springs, and aquifer attribution (where available) -         Basin boundary extents
