Estimates of inflows into catchments was a core component of the hydrologic condition analysis done for the 2020 Basin Plan Evaluation. These catchment inflows were determined based on daily runoff outputs produced by the Bureau of Meteorology's (BOM) Australian Landscape Water Balance model (AWRA-L v6). Usage of this dataset is licenced under the Creative Commons Attribution Australia Licence.
Additionally the MDBA used these catchment inflows to categorise catchments across water years from a wetness perspective (i.e. 'climate categorisation').
