The Rio Jarauçu is a river in the state of Pará, Brazil, flowing through the Tapajós-Xingu moist forests as a tributary of the larger Xingu River. The river's basin, or microbacia, is noted for a high incidence of voçorocas, which are large erosion gullies. These features are causing significant environmental and socioeconomic impacts within the region. The river's course is situated near the municipality of Brasil Novo. The surrounding landscape is characterized by the dense, biodiverse vegetation typical of the Amazonian moist forests. The river's status as a tributary of the Xingu suggests it is part of a vast and remote river network. There is no indication of any restrictions or regulations specific to paddling on this water body. The presence of active erosion features suggests that paddlers should be aware of potential for unstable banks and changing channel morphology, which could present hazards. The area's ecological significance and the ongoing environmental changes provide a context of a dynamic and ecologically rich, yet impacted, Amazonian tributary.
