Pollution and environmental degradation
Even in the 1920s and 1930s, the river was utilised for fishing and sports activities were famous as were the nautical races on the river. During this period boat race clubs were created along the length of the river, such as the Club of the Tietê races and the Espéria, clubs that exist till now.
In September 2010 National Geographic identified the river as the most polluted in Brazil.

Todos os anos o mesmo problema se repete no interior de São Paulo: os rios são invadidos por uma espuma, resultado da poluição agravada pelo tempo mais seco. No outono e no inverno, o Rio Tietê, o mais importante do estado, fica coberto pelos blocos brancos que, apesar de parecerem limpos, é resultado do desrespeito à conservação dos rios.

O Rio Tietê, já tão sujo e poluído, ganhou cores mais escuras na manhã desta quarta-feira (9), no trecho que corta Salto, após receber as águas – e a sujeira – da Grande São Paulo, devido fortes chuvas do feriado prolongado.
