Otron Lake

Otron is associated with Lake Musters in the dry interior of central Patagonia. The Senguerr River flows from the Andes into the lake basin, where Musters lies beside the much shallower Colhué Huapi. The lakes form the end of a largely closed drainage system. Their waters and nearby wetlands stand out amid the dry steppe, receiving a river whose source lies in the wetter mountain country far to the west.
