Nas últimas décadas, os ecossistemas aquáticos têm sido alterados de maneira significativa. Diante disso, faz-se necessária a conservação dos recursos hídricos. O objetivo deste trabalho é estimar a qualidade ambiental do Rio Piumhi, que já sofreu transposição de suas águas, por meio de protocolo de avaliação rápida das características da água e sedimentos, situação e estado de conservação das margens, matas ciliares, cobertura vegetal e presença de erosão e assoreamento. A aplicação do protocolo gera empoderamento da sociedade quanto à gestão dos recursos hídricos. O protocolo com treze parâmetros foi aplicado em seis locais sujeitos às atividades humanas, na qual foram atribuídas pontuações. Foi possível constatar que três dos seis locais analisados se encontraram em boa, um em ótima e dois em regular condição. A maior parte dos locais apresentou cobertura vegetal nativa degradada, sendo urgente a preservação desse curso hídrico. Palavras-chave: Rio Piumhi. Protocolo de avaliação rápida. Bacia hidrográfica. Application of the rapid evaluation protocol (rep) on the characterization of the environmental quality of the Rio Piumhi sections, Minas Gerais - Brazil Abstract In recent decades, aquatic ecosystems have changed significantly. Therefore, it is necessary to conserve water resources. The objective of this work is to estimate the environmental quality of the Piumhi River, which has already undergone transposition of its waters, by means of a rapid evaluation protocol of water and sediment characteristics, situation and state of conservation of banks, riparian forests, vegetation cover and presence of erosion and siltation. The application of the protocol generates the empowerment of society regarding the management of water resources. The protocol with thirteen parameters was applied in six locations subject to human activities, in which scores were assigned. It was possible to verify that three of the six places analyzed were in good condition, one in excellent condition and two in regular condition. Most of the locations had degraded native vegetation cover, making it imperative to preserve this water course Keywords: Piumhi River. Rapid evaluation protocol. Watershed.
