The dam is considered one of the World's Seven Modern Wonders, clocking in at 7.2km (4.5mi) long, 65 stories high, with a maximum flow more than 40 times that of Iguacu Falls on a good day.
In fact, Itaipu marks the spot where an almost equally epic cascade was once the centerpiece of Guaira Falls National Park. The "Seven Falls of Guaira" (actually 18 cascades on the Parana River, gushing twice as much water as Niagara Falls) were drowned in 1982 when the dam was under construction.
The national park was dissolved, the cliffs dynamited underwater to ensure safer navigation on the new reservoir, and today Itaipu produces more than 20% of Brazil's electricity.
