The dam's spillway contains 37 floodgates, each with a discharge capacity for a total discharge of . The average long-term flow at the dam is and the record maximum flow was which was reached on October 2, 1983. The dam's navigation lock is long, wide and affords transportation on the Paraná and Tietê Rivers. It was inaugurated January 1998.

Power station

The dam's power station contains 14 x generators that are powered by Kaplan turbines for a total installed capacity of . In addition, the power station contains two service generators for powering the dam's facilities itself. Together, dam's generators are designed to discharge of water, bringing the total discharge capability of the dam to at a reservoir elevation of above sea level.
