The Iguazu Falls have experienced a massive increase in water flow following intense rainfall in the Iguazu River basin. Discharge levels reached a peak of approximately 8.37 million liters per second, significantly exceeding the typical range of 1.5 to 1.8 million liters per second.

This surge, which began trending upward in late August, is attributed to accumulated upstream precipitation and early effects of the El Niño phenomenon. Management and conservation teams in Argentina and Brazil, including the Chico Mendes Institute for Biodiversity Conservation (ICMBio), are monitoring the situation to assess environmental impacts and safety conditions.
