Description: The flow line paths dataset was derived from the regional watertable surface, which was created using groundwater elevations from a subset of bores attributed to the Barkly, Narpa, Cockroach and Toko group aquifers of the Georgina Basin. At the basin-scale, these aquifers are assumed to be hydraulically connected due to the absence of regional aquitards or other geological structures. These aquifers, commonly referred to in this report as the ‘regionally unconfined aquifers’, are the most common aquifers for groundwater supplies over most of the SNG region (except for the far southern parts where the Georgina Basin is overlain by younger Mesozoic aquifers of the Great Artesian Basin).From analysis of the mapping, three regional groundwater flow systems were identified:1. Roper River flow system2. Lawn Hill Creek flow system3. Southern Georgina Basin flow system.
