The Preto River is a river located in the state of Paraíba, Brazil. It is a tributary of the Paraíba River, the principal river of the state. The Preto River flows generally in a northeasterly direction, eventually joining the Paraíba River. It is important for local agriculture, providing water for irrigation and livestock. The river basin is characterized by tropical semi-arid vegetation (Caatinga). Water management and conservation are critical issues in the region due to seasonal drought and increasing demand.
