The 1,360 km long Rio Grande [ˌχiu ˈɡɾãd͡ʒi] is the left headwaters of the Paraná in Brazil / South America .

River course

The river has its source in Brazil in the south of the state of Minas Gerais in the Serra da Mantiqueira . From there, the water of the Rio Grande flows mainly in a westerly direction and is dammed up by hydropower plants to form several, sometimes very large, reservoirs . Finally, the Rio Grande combined in Ilha Solteira Dam (, 21,06 1,195 cubic kilometers square kilometers) with the Paranaíba to Parana .

The Furnas reservoir is important for regulating the water flow of the Rio Grande . It usually fills up during the rainy season from November to April and then emptied during the dry season from May to October. The Furnas Reservoir is the seventh largest reservoir in Brazil in terms of both area and volume.
