Guarapiranga Reservoir

Guarapiranga is a reservoir in the southern part of São Paulo that covers roughly 26.6 square kilometers and stretches almost 20 kilometers in length. Its shoreline alternates between forested hills, residential areas, and open sections with marinas.

The British company São Paulo Tramway, Light and Power Company constructed the reservoir in 1906 to generate hydroelectric power for the city. In 1928 its function changed to provide drinking water for the growing population.

The name comes from a Guaraní word for a native tree that once grew along the shores. Today you can see anglers and families spending time at the artificial beaches on weekends.

Access to the water happens through public parks and private clubs at different points along the shore. Some areas allow walks along the waterline while other sections remain visible only from outside.

Several small islands lie scattered across the water and offer habitats for birds and other regional wildlife. These islands also help prevent flooding in the surrounding area.
