Description and history

The first Indigenous Park in Brazil was created in the river basin by the Brazilian government in the early 1960s. This park marks the first indigenous territory recognized by the Brazilian government and it was the world's largest indigenous preserve on the date of its creation. Currently, fourteen tribes live within Xingu Indigenous Park, surviving on natural resources and extracting from the river most of what they need for food and water.{{Cite web |title=Xingu - Indigenous Peoples in Brazil |url=https://pib.socioambiental.org/en/Povo:Xingu |access-date=2023-09-25 |website=pib.socioambiental.org}}

The Brazilian government built the Belo Monte Dam on the Lower Xingu, which began operations in 2019 and is the world's fifth-largest hydroelectric dam. Construction of this dam was under legal challenge by environment and indigenous groups, who assert the dam would have negative environmental and social impacts along with reducing the flow by up to 80% along a {{Convert|100|km|mi|abbr=on|-1}} stretch known as the Volta Grande ("Big Bend").{{cite web|title=Summary and History of the Belo Monte Dam: Rainforest Foundation |url=http://www.rainforestfoundationuk.org/files/Belo%20Monte%20Factsheet.pdf |publisher=Summary and History of the Belo Monte Dam: Rainforest Foundation |access-date=9 March 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110106172656/http://rainforestfoundationuk.org/files/Belo%20Monte%20Factsheet.pdf |archive-date=6 January 2011 }} The river flow in this stretch is highly complex and includes major sections of rapids.{{Cite journal |author1=Fitzgerald |author2=Perez | author3=Sousa |author4=Gonçalves |author5=Py-Daniel |author6=Lujan |author7=Zuanon |author8=Winemiller |author9=Lundberg |date=2018 |title=Diversity and community structure of rapids-dwelling fishes of the Xingu River: Implications for conservation amid large-scale hydroelectric development | journal=Biological Conservation |volume=222 | pages=104–112 |doi=10.1016/j.biocon.2018.04.002 |s2cid=53625155 |doi-access=free }} More than 450 fish species have been documented in the Xingu River Basin and it is estimated that the total is around 600 fish species, including many endemics.Camargo, M., T.

In the Upper Xingu region was a highly self-organized pre-Columbian anthropogenic landscape, including deposits of fertile agricultural terra preta, black soil in Portuguese, with a network of roads and polities each of which covered about 250 square kilometers.{{cite journal|last1=Heckenberger|first1=Michael J.|author-first2=J.
