Highest annual flow reached on October 26
On October 26, the Iguazu Falls reached 17.7 million liters per second, 11 times the historic average. The flow was already around 16 million liters per second the following morning.

The Iguazu Falls recorded a flow of 17.7 million liters per second in the early hours of Monday, October 26. By the morning, the discharge was about 16 million liters per second. This level is 11 times the historic average of 1.5 million liters per second, resulting from intense rains in Paraná and the Iguazu River basin.
The Iguazu Falls Walkway has been closed preventively since October 11, according to the safety protocols of Iguazu National Park. Reopening will depend on the river conditions in the coming days and a technical assessment of the structure. The paths to Poço Preto and Bananeiras are also temporarily closed for safety.
Iguazu National Park, managed by the Chico Mendes Institute for Biodiversity Conservation (ICMBio), has its tourist visitation administered by the concessionaire Urbia+Cataratas. The park is recognized as a UNESCO World Natural Heritage site.
For visitors, the Falls Trail and its main viewpoints remain open. The Falls Walkway, São João Circuit, Power Plant Area, and Poço Preto Trail are closed, while the Bananeiras Trail is shut for construction.
