Paraitinga River (upper Tietê River tributary)

The Paraitinga River is a significant tributary of the upper Tietê River in the state of São Paulo, Brazil. It plays a crucial role in the water supply and ecosystem of the region.

The river's source is located in the Serra do Mar mountain range, flowing westward before joining the Tietê River. Its course is characterized by diverse landscapes, including areas of preserved Atlantic Forest and agricultural lands.

The Paraitinga River's water quality is subject to environmental pressures, primarily due to agricultural runoff and urbanization within its watershed. Monitoring and conservation efforts are underway to mitigate these impacts and preserve the river's ecological integrity. The river is also important for recreational activities, such as fishing and ecotourism, in certain areas.
