The Manso Dam (Portuguese: Represa de Manso) is a hydroelectric dam on the Manso River, a tributary of the Cuiabá River, in the state of Mato Grosso, Brazil. Completed in 1999, it generates enough electricity for 300,000 people, and the reservoir is a tourist attraction. The dam displaced many families from the area now covered by the reservoir, and the submerged, decaying vegetation has had negative impact on water quality in and below the dam, affecting edible fish stocks.

The dam impounds the Manso River in the upper Paraguay sub-basin of the Paraná basin. The reservoir is in the municipalities of Chapada dos Guimarães and Rosário Oeste in the midwest region of Mato Grosso. It is the largest in the Paraopeba system. The dam is 86 kilometres (53 mi) from Cuiabá, the state capital, along good roads. It is about 360 metres (1,180 ft) above sea level. The lake has become a tourist attraction.

The dam project was launched in 1974, when a flood of the Cuiabá River left more than 20% of the population of the state capital homeless. The objective was to control flooding while generating electricity, developing tourism and supporting irrigation. Construction began in 1988 and was completed in 1999. The dam has a height of 72 metres (236 ft). 200,000 cubic metres (7,100,000 cu ft) of concrete were used in construction. Total cost was R$340 million. The reservoir covers an area of 427 square kilometres (165 sq mi). It was full in 2001.

The operating contract is 70% owned by Eletrobras Furnas. Installed capacity is 212 MW, with guaranteed output of 92 MW. It can meet the power demands of 300,000 people. After an extended drought, in December 2015 the water level had fallen to 28.7% of capacity. However, record rainfall raised it to 76% by June 2016. At 70% capacity the water line is 6.59 metres (21.6 ft) above the minimum operating level.

Relatively little information was provided about the dam to the affected people in Mato Grosso. 109 properties were requisitioned for the project, and between 652 and 1,065 families were displaced. The displaced families were settled in areas with sandy soil, unsuitable for agriculture, and given insanitary straw shacks as homes.
