The Represa de Belo Monte is the reservoir created by the Belo Monte Dam complex on the Xingu River in the state of Pará, in northern Brazil. This massive hydroelectric impoundment — the second largest in Brazil and among the largest in the world by installed capacity at 11,233 MW — flooded approximately 516 km² of land when it began operations in 2016, an area larger than the city of Chicago. The reservoir sits at coordinates approximately 3°7′40″S, 51°46′33″W, in the Região Geográfica Intermediária de Altamira. The dam complex includes three structures: the main Belo Monte Dam (90 m tall), the Pimental Dam (36 m), and the Bela Vista Dam (33 m), all impounding the Xingu River. The reservoir is operated by Norte Energia S.A. under the Eletronorte umbrella. Anglers considering a visit should be fully aware that this water body exists within a profoundly altered ecosystem, and the fishing experience here is inseparable from the dramatic environmental changes that have reshaped fish populations, migration patterns, and overall aquatic ecology since the dam's construction.
