Açunguí River
river in Paraná, Brazil
The Açunguí River (Portuguese: Rio Açunguí) is a river of Paraná state in southern Brazil. It is a headwater of the Ribeira de Iguape River.
Basin
The Açungui river basin is the last natural reserve of unpolluted water to supply the metropolitan region of Curitiba.
The basin includes the Açungui National Forest, created in 1944 under the government of Getúlio Vargas as the Romário Martins Park, with an area of 3,728 hectares (9,210 acres).
The national forest preserves araucarias.
The river basin covers about 1,800 square kilometres (690 sq mi).
Course
The river rises in the foothills of the Serra de São Luiz do Purunã, Paraná.
The river rises to the northwest of Curitiba and flows in a generally northeast direction to join the Ribeira River, which flows east into São Paulo.
The Açungui valley is steep, with many small canyons and very close to the National Forest, so the environment has been well preserved.
There are rapids along the river, particularly in the Canyon do Acalantilado, making it an excellent place for rafting.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Açunguí River”, the useful work is to connect “river in Paraná, Brazil” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 2, 2026. The linked authority identifier is Q10361524. Authority coordinates are -24.906, -49.472. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1944.
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.
