Grant Group and Poole Sandstone potentiometric surface

This data set contains hydraulic head values for the interconnected Grant Group and Poole Sandstone aquifers obtained from multiple sources including: (i) field measurement data stored and available from from the Department of Water and Environmental Regulation Water Information Reporting online data portal, (ii) field measurement data collected as part of targeted field investigations in Taylor et al. (2018) and (iii) field measurements collated from various hydrogeological investigation reports for Indigenous communities and pastoral station groundwater supplies. ArcGIS was used to interpolate point hydraulic head data into a continuous potentiometric surface for the extent of the Grant Group and Poole Sandstone aquifers within the Fitzroy catchment and some surrounding areas. The point and grided data is presented as a reduced standing water level in metres Australian Height Datum.The purpose of the data set was to interpret the scale and directions of groundwater flow in both aquifers.
