Waterfalls in flood: water force this week
Marco Três newsroom · edited by Annie Grellmann
The flow of the Iguaçu River at the Waterfalls is 2,160 m³/s, 1.44 times the historic average of 1,500 m³/s.
Today's measurement indicates 2,160 m³/s (equivalent to 1.5 million liters per second), which corresponds to 1.44 times the historic average flow of 1,500 m³/s. This ranking places the river among the top 5% of values ever recorded, although still far below the all-time record of 46,300 m³/s set in June 2014.
In practical terms, the current equals about one Olympic-size swimming pool every 1.2 seconds, or 216 water-truck loads per second, and in roughly 20 seconds it exceeds the daily water consumption of the entire population of Foz do Iguaçu (285 thousand residents). The water may appear darker, but this is only sediment carried by rain in the basin, not dirt.
Although the flood does not imply a total park closure, there is a risk that the final walkway of the Waterfalls may be temporarily blocked for safety, as announced in the operational decision earlier today. The viewpoints remain open. To confirm the status in real time, check the official Waterfalls page before leaving home.
What this means for you: the water force is high, ideal for those who want to feel the power of the falls, but verify whether the final walkway is open and plan to arrive early to avoid lines and enjoy the still-available viewpoints.
