Rio Paraibuna flows through the state of Minas Gerais, Brazil, draining a significant portion of the southeastern highlands before eventually contributing to the broader Atlantic watershed system. The river is associated with several impoundments, most notably the Barragem de Chapéu d'Uvas and the Represa do Rio Paraibuna, which together shape much of the fishing character along this waterway. The reservoir at Chapéu d'Uvas is operated by the Companhia de Saneamento Municipal (CESAMA) and serves as an important water resource for the region. The Represa do Rio Paraibuna covers approximately 1.5 square miles of open water, offering anglers a mix of reservoir and river fishing opportunities across the system.
