Spillway reopened at 9:30 a.m. on 10/26/2026, initial discharge of 3.1 million L/s
Itaipu reopened the spillway at 9:30 a.m. on 10/26/2026 after a closure of less than 17 hours. The initial discharge will be 3.1 million L/s, with a forecasted rise of 2.5 m in the Paraná River within 24 hours.
The binational Itaipu hydroelectric plant reopened the spillway on Monday morning, October 26 2026, at 9:30 a.m., after it had been closed on Sunday, October 25, at 5:32 p.m., for less than 17 hours.
The reopening was carried out on the left-bank gates, with an initial discharge rate of approximately 3.1 million liters of water per second, according to a statement from the Superintendency of Operations, linked to the entity’s Technical Directorate.
The measure aims to keep the reservoir level under control given the high volume of water entering the system, following the strategy of closing the spillway to reduce the impact of the Paraná River flood, intensified by the increased flow of the Iguazú River, which was approaching 20 million liters per second.
Before the closure, the spillway had remained open for 26 consecutive days. With the new discharge, authorities expect the Paraná River level to rise about 2.5 meters in the next 24 hours.
