Rio Uberabinha flows through the western portion of Minas Gerais state in southeastern Brazil, draining into the broader upper Paraná River Basin. The river is part of an extensive hydrographic network in the Triângulo Mineiro region, sharing the landscape with major waterways such as the Araguari, Tijuco, and Uberaba rivers, all of which contribute to the hydrological connectivity of this basin. Classified as a Class 2 water body under both CONAMA (2005) federal standards and the Minas Gerais state Joint Regulatory Resolution (COPAM, 2008), the Uberabinha is recognized as a river of ecological and water-quality significance in the region. The Nova Ponte reservoir, located on the Araguari River system upstream, plays a role in moderating seasonal flow differences in the broader watershed — storing water during the rainy season and releasing it during dry months — which influences hydrological conditions across connected waterways including the Uberabinha.
