Sucunduri River
river in Amazonas, Brazil

Sucunduri River (Portuguese: Rio Sucundurí) is a river of Amazonas state in north-western Brazil, one of the main headwaters of the Canumã River.
Course
The Sucunduri River rises in the 808,312 hectares (1,997,380 acres) Sucunduri State Park in the municipality of Apuí.
The Monte Cristo rapids on the Sucunduri is an area with great numbers and diversity of animals and birds.
In 2006 it was also the location of an illegal mining settlement.
The Monte Cristo rapids and the Sucunduri River Falls (Saltos do Rio Sucunduri) are well-known attractions.
The river flows through the 896,411 hectares (2,215,080 acres) Acari National Park created by president Dilma Rousseff in 2016 in the last week before her provisional removal from office.
Part of the river's basin is in the 19,582 square kilometres (7,561 sq mi) Juruena National Park, one of the largest conservation units in Brazil.
The Sucunduri basin occupies 10% of the park.
The Trans-Amazonian Highway crosses the Sucunduri River.
Further north it merges with the Acari and the downstream section is known as the Canumã River.

Why this record matters
The phrase “river in Amazonas, Brazil” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 6, 2026. The linked authority identifier is Q7633203. Authority coordinates are -5.283, -39.671. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2006 and 2016.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. 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.
