Itaipú

Itaipú Binacional is the hydropower entity jointly owned by Paraguay and Brazil on the Paraná River and one of the pillars of Paraguay’s electricity system.

Infrastructure & Environment - Sep 21, 2026Mymba Kuéra rescued thousands of animals – but Itaipú’s flooding came at a high ecological cost

When the Itaipú reservoir was filled in 1982, Paraguay’s Operativo Mymba Kuéra recovered 27,150 wild animals; the BBC reports around 11,000 more on the Brazilian side. The operation was remarkable, but it could mitigate only part of the damage: the new reservoir flooded about 1,350 square kilometres, submerged the Saltos del Guairá and permanently altered habitats and fish communities. Historical sources even disagree on the total number of animals rescued.

Economy - Sep 20, 2026Itaipu keeps spillway open as flow rises 61%, with operation subject to change if rains continue

Technicians explained the alternation between spillway channels, while Silver Guerrero told Radio Nacional that operations could change depending on rainfall, with minimal impact on riverside residents for now, normal generation and tourist visits available.
