Fishing near Sorocaba, São Paulo

Sorocaba sits in the interior of São Paulo state, where the Rio Sorocaba drains a basin of roughly 5,256 km² before joining the Rio Tietê. The urban stretch of the Rio Sorocaba carries significant sewage and industrial effluent, making fishing there inadvisable for consumption; the productive water is found at the upper course near the Represa de Itupararanga and at the lower course approaching the Tietê confluence. Beyond the rivers, the region around Sorocaba has a well-established culture of pay-to-fish lakes (pesqueiros), several of which operate within the city itself and in nearby towns such as Boituva and Itu.
