Manso dam, Brazil


The Manso dam is on river Manso, 100 km north of Chapada dos Guimares city in Mato Grosso state. It started to produce electricity in 2000 as a project of Brazilian state company Furnas Centrais Eletricas (Furnas), but today it belongs for 70% to Furnas and for 30% to private company Produtores Energticos de Manso S/A (Proman). The reservoir flooded around 47 000 hectares and displaced famers, fishermen and quilombolas.
