Andean Patagonia includes a large lake district with numerous deep and shallow lakes of glacial origin, surrounded by native forests. In this study, we assessed dissolved organic carbon (DOC) concentrations and dissolved organic matter (DOM) absorbance and fluorescence properties of deep and shallow lakes with contrasting hydrogeomorphic features. Two deep ultraoligotrophic lakes (Zmax>90m) and two shallow lakes (Zmax
