Water reaches 16 million liters per second and covers the walkway, which remains closed
On October 25, 2026, Iguazu Falls in Foz do Iguaçu (PR) reached the highest flow of the year, with 16 million liters per second. The current caused the water to overrun the walkway, which stays closed to the public.
The measurement taken at 5 p.m. by Copel showed that the water volume at the falls reached 16 million liters per second, about ten times the historic average of 1.5 million liters per second. Although it is the highest flow recorded in 2026, it is still below the record 46 million liters per second set in 2014.
The walkway that allows tourists to approach the falls has been closed since October 11, when the strength of the current required the removal of protective railings to reduce the structure’s resistance. Safety protocol mandates closing the walkway when flow exceeds 8.5 million liters per second and removing the railings once it reaches 15 million liters per second.
Iguazu National Park remains open, but sections of the Falls Trail and other attractions stay temporarily closed as a precaution. Closed points include the Lower Viewpoint of the Naipi Area, the São João Circuit, the Power Plant Area, the Black-Pool Path, and the Canafístula Trail. Teams from the concessionaire Urbia + Cataratas and ICMBio continue monitoring river volume and safety conditions, with no set date for reopening the affected sections.
