Río Grande (Bolivia)

The Río Grande (or Río Guapay) in Bolivia rises on the southern slope of the Sierra de Cochabamba, east of the city of Cochabamba, at coord|17|26|11|S|65|52|22|W. At its source it is known as the Río Rocha and crosses the Cochabamba valley basin in a westerly direction. After 65 km the river turns southeastand after another 50 km joins the Río Arque at coord|17|42|10|S|66|14|45|W and an elevation of 2.350 m.

From this junction the river is given the name Río Caine for 162 km and continues to flow in a southeasterly direction, before it is called "Río Grande". After a total of 500 km the river turns northeast and in a wide curve flows round the lowland city of Santa Cruz.

After 1.438 km, the Río Grande joins the Río Ichilo at coord|15|48|09|S|64|43|47|W which is a tributary to the Río Mamoré.
