Manicoré River
river in Amazonas, Brazil
Manicoré River (Portuguese: Rio Manicoré) is a river of Amazonas state in north-western Brazil. It is a tributary of the Madeira River and merges into this river about 3 km (1.9 mi) upstream from the town of Manicoré.
The headwaters of the river are in the Campos Amazônicos National Park, a 961,318 hectares (2,375,470 acres) protected area created in 2006 that holds an unusual enclave of cerrado vegetation in the Amazon rainforest.
Further north the river defines part of the eastern boundary of the 151,993 hectares (375,580 acres) Campos de Manicoré Environmental Protection Area, created in April 2016 just before the provisional removal of president Dilma Rousseff.
It then flows through the 359,138 hectares (887,450 acres) Manicoré Biological Reserve, which was created at the same time.
This brief starts where responsible research should: with the source description of “Manicoré River” as river in Amazonas, Brazil. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as river in Amazonas, Brazil. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Aug 4, 2026. The linked authority identifier is Q6749494. Authority coordinates are -5.859, -61.329. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2006 and 2016.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
