The Spillway
Font Size

What is it?
The spillway is used to drain the excess water that falls on the reservoir during the rainy season.

What is there to do?
Watch the spillway in action between the months of December and February when the steel floodgates are open during the rainy season. The opening of the spillway does not follow a preset schedule. It is directly linked to the level of the lake. Those lucky enough to watch the water draining out through the three chutes have the chance of beholding an unforgettable display. The outflow of Itaipu's spillway is equivalent to 40 Iguazu Falls. That deluge slides down a 30 meter toboggan to form a 10 meter overflow, and then finally goes back to the rocky bed of the Paraná River, at 40 meters deep.

Useful Information:
The spillway panoramic view from the central belvedere is offered as part of the Special Tour, Tourist Excursion and Company Tour.
