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]
Many of the dams and reservoirs in Brazil listed below are used primarily used to produce hydroelectric power. Other uses include flood control, irrigation and fisheries.
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]
Construction on the dam began in 1957 and was the first large dam in Brazil. It was built by Wimpey Construction and was completed in 1963. [1] It is built on the canyon of the Grande River, before joining the Sapucaí River downstream. The dam is 127 metres (417 ft) tall, 550 metres (1,800 ft) long, and 15 metres (49 ft) wide at its crest.

At 11.38 kilometres (7.07 mi) in length, it is the longest dam in Brazil. [3] [4] The 22 metres (72 ft) tall dam creates a reservoir with a 19.9 cubic kilometres (16,100,000 acre⋅ft) capacity and surface area of 2,250 square kilometres (870 sq mi).
The main dam's Creager-type service spillway is the second largest in the world with a maximum capacity of 110,000 cubic metres per second (3,900,000 cu ft/s). It is controlled by 20 floodgates measuring 20 by 21 metres (66 ft × 69 ft).
