Iguazu Falls reach flow 3.5 times above average

Iguazu Falls reopened to the public a little over a week ago and continue to surprise visitors with an exceptional water volume. On September 22, 2026, the flow reached 3.5 times the normal average, according to official hydrological monitoring data from Copel. The volume surpassed the safety threshold of 8 million liters per second on Friday, the 11th, reaching more than five times the historic average. Between early morning and sunrise on Saturday, the 12th, the flow peaked at 10.1 million liters per second, more than six times the normal average. As the volume gradually receded, the flow measured 6.7 million liters per second on the 14th, and a technical inspection concluded that the structure was safe again. The following day, the 15th, the Devil's Throat lookout was reopened to the public. The flood is a result of accumulated rainfall in the Iguaçu River basin. Continuous monitoring is carried out by the concessionaire Urbia+Cataratas and the Chico Mendes Institute for Biodiversity Conservation (ICMBio). Despite the high volume, levels remain within the safe margin. Park management maintains normal visitation, operating Monday through Friday from 9 a.m. to 4 p.m., with visitors allowed to stay until 5:30 p.m. The Iguaçu National Park, which receives more than two million visitors annually, continues to be one of South America's major tourist destinations.
