Rio Uruçuí-Vermelho is one of the principal right-bank tributaries of the Rio Parnaíba and serves as the heart of sport fishing in southwestern Piauí. Rising in the Serra do Penitente, the river winds through classic Cerrado landscape, passing through Bom Jesus, Currais, and Santa Filomena before completing its roughly 400-kilometer journey to meet the Parnaíba near the town of Uruçuí. Unlike the intermittent rivers typical of the sertão, the Uruçuí-Vermelho maintains a reasonable flow year-round, sustained by veredas (gallery forests), wetlands, and the small chapadas of the Cerrado plateau. This hydrological stability makes the river fishable in virtually any season, with a pronounced peak during the drawdown and dry period when fish concentrate in the deeper pools. The river averages 2 to 6 meters in depth, with the main pools reaching up to 10 meters, and water temperatures typically range between 26°C and 32°C during prime fishing conditions.

The main pools (poços) are the defining fishing spots of the Uruçuí-Vermelho. These deep holes — reaching up to 10 meters — are where surubim hold during the day and where all species concentrate during low water. Rocky riffles and runs throughout the middle section are the go-to spots for piau. The area near Barreiras do Piauí is a documented fishing location along the river. The lower river near the confluence with the Rio Parnaíba is particularly notable for larger surubim and the occasional dourado. Anglers traveling from Brasília and other distant cities specifically target this river, a testament to the quality of its fishery.
