Short summary
River systems that support high biodiversity profiles are conservation priorities worldwide. Understanding river ecosystem thresholds to low-flow conditions is important for conservation practices. In this study, the groundwater components for a hydrological model were distributed to provide daily baseflow and streamflow estimates needed for reserve determination. The modelling approach was applied to a RAMSAR lake system under threat by agricultural expansion and climatic fluctuations.
