Popis:	Water balance studies with stable water isotopes have rarely been conducted in remote and tropical wetland areas. As such, little is known regarding the water balance and groundwater-surface water interaction in the Pantanal, one of the largest and most pristine wetlands in the world. We applied MINATreS, a water balance model utilizing stable water isotopes (δ 18 O, δ 2 H) and chloride (Cl - ) to assess the dry-season hydrological processes controlling groundwater-surface water interactions and the water balance of six floodplain lakes in the northern Pantanal, Brazil. Qualitatively, all lakes exhibited similarity in hydrological controls. Quantitatively, they differed significantly due to morphological differences in controlling groundwater inflow and lake volume. Our approach is readily transferable to other remote and tropical wetland systems with minimal data input requirements, which is useful in regions with sparse hydrometric monitoring.
