The Tiete River is a Brazilian river in the state of Sao Paulo. The source is in Salesopolis in the Serra do Mar, at 1,120 m altitude. Although the source is at most 22 kilometres (14 mi) from the coast, the escarpment of the Serra do Mar forces it to run in the opposite direction, to the interior, going through the state of Sao Paulo from southeast to northwest till it runs into the artificial lake formed by Eng Souza Dias (Jupia) Dam on the Parana River, in the municipality of Tres Lagoas, about 50 kilometres (31 mi) from the city of Pereira Barreto.
