Abstract: 
Ibera wetland is one of the most pristine and singular ecosystems of South America. Satellite-derived thermal analysis of itslacustrine system supported the existence of a groundwater connection with the Yacyreta reservoir through basaltic fractureslocated along the ancient river bed of the Parana. The groundwater outflow would be located on the geological discontinuity ofthe eastern border of Ibera wetland, concretely around Laguna Ibera´ and Laguna Luna–Disparo. This new sign of connectioncomes on top of the hydrological signs which already exist. A call to prudence recommends not extending the recently projectedincrease of the water level of Yacyreta reservoir. Deeper hydrogeological studies should analyze the hypothesis emerged fromthis study before modifying the water level of Yacyreta.
