Lineage	All available records of the species collected after 1 January 1994 were collated and assessed for accuracy. Using the framework of the Australian Hydrological Geospatial Fabric V2 surface hydrology network (Geofabric), all records were allocated a stream segment. Attributes from the National Environmental Stream Attributes Database and River Styles® geomorphology were allocated to all stream segments. MaxEnt 3.3.3 was used to model the current geographic distribution of each listed threatened freshwater aquatic species or population. The logistic output was used to plot the predicted distribution of each species. This output equates to a probability that the species will be observed in each river reach, given the environmental conditions that exist there relative to the environmental conditions where the species is known to occur. For this mapping, above 33% probability was considered predicted presence. Only stream segments with a modelled average daily flow of more than five megalitres were selected for output. In addition, predicted separate populations were connected by manual interpretation. The predicted values for each river reach were converted from the Geofabric framework to the higher resolution 2013 NSW Strahler Stream Order Hydroline.
