Water is brought towards the power station intake through a channel which is 450 metres (1,480 ft) long and 90 metres (300 ft) wide. The actual power intake structure is 70 metres (230 ft) high, 108 metres (354 ft) wide and allows for a maximum reservoir level depletion of 47 metres (154 ft). Six wheel-type gates facilitate bring water into the power station. An additional gate exists for maintenance purposes.

At the time of completion, the dam was the tallest and largest concrete face rock-fill dam in the world. It was also the first of its type to have a reservoir of its size. The techniques to construction the dam were instrumental and an advancement as 50,000 cubic metres (1,800,000 cu ft) of

The Bento Munhoz da Rocha Netto Dam is an 828-metre (2,717 ft) long and 160-metre (520 ft) high concrete face rock-fill type. The dam contains a total 14,138,000 cubic metres (499,300,000 cu ft) of material which includes 14,000,000 cubic metres (490,000,000 cu ft) of
