Claro River (lower Tietê River tributary)

The Claro River is a river located in the state of São Paulo, Brazil. It is a tributary of the Tietê River, entering the Tietê in its lower reaches, after the Barra Bonita dam. Its drainage basin is situated primarily within the central-western part of São Paulo state, encompassing municipalities known for agriculture and cattle ranching. The river is known to be impacted by agricultural runoff and urban development in the region, contributing to water quality issues within the larger Tietê River watershed. Data on the Claro River's length, discharge, and exact hydrological characteristics is often conflated with other rivers of the same name in Brazil, requiring careful source verification.
