The dam is 196 metres (643 ft) high, equivalent to a 65-story building. [21] Though it is the seventh largest reservoir in size in Brazil, the Itaipu's reservoir has the highest ratio of electricity production to flooded area. For the 14,000 MW installed power, 1,350 square kilometres (520 sq mi) were flooded.
The dam is 307 kilometres (191 mi) from the state capital of Fortaleza. [3] It is the largest multiple-use public reservoir in Brazil and the largest dam in Brazil on an intermittent river. [2] [4] The reservoir has 6,700,000,000 cubic metres (2.4 × 10 11 cu ft) capacity, of which 250,000,000 cubic metres (8.8 × 10 9 cu ft) is dead volume. [2]

The Serra da Mesa Dam, once known as Sao Felix, is an embankment dam on the Tocantins River near Minaçu in Goiás, Brazil. The dam serves an associated hydroelectric power plant with a 1,275 megawatts (1,710,000 hp) installed capacity. The dam creates the largest reservoir by volume in Brazil. [1]
The Three Gorges Dam in Hubei, China, has the world's largest instantaneous generating capacity at 22,500 MW of power. In second place is the Baihetan Dam, also in China, with a capacity of 16,000 MW. The Itaipu Dam in Paraguay and Brazil is the third largest with 14,000 MW of power.
The upstream cofferdam was 45 metres (148 ft) high and allowed the diversion of up to 7,700 cubic metres per second (270,000 cu ft/s) of water. The dam began to impound the reservoir in 1980 and by October it was filled and complete. [4] At the time of completion, the dam was the tallest and largest concrete face rock-fill dam in the world.
The Billings Reservoir (locally known as Represa Billings) is the largest reservoir in São Paulo, Brazil, covering a total of 127 km 2 (49 sq mi). It is named after Asa White Kenney Billings, the American hydroelectric engineer who was instrumental in building it. The Portuguese word represa also means "dam".
