The Río Mamoré is the right source river of the Río Madeira , the largest tributary of the Amazon in South America. The Río Mamoré, with a water flow of around 8200 m² / s and a length of around 1170 kilometers, is one of the largest rivers in Bolivia , which arises from the confluence of the Río Ichilo and Río Chapare . The Río Grande is the longest right tributary and is also considered a source river.

River course

The headwaters of the Río Mamoré arise on the northern slopes of the Cordillera of Cochabamba , east of the city of Cochabamba . Another possible main river is the Río Chimoré , which flows into the Río Ichilo at Puerto Villaroel, about 150 kilometers before it joins the Río Chapare . From here the river bears the name Río Mamoré. About twenty kilometers after the confluence, the Río Grande , which has comparatively little water and is often referred to as the source river because of its length, flows from the right . The Mamoré now flows past Trinidad . The Rio Guaporé flows into the border with Brazil . At Villa Bella, the Río Mamoré joins the Río Beni, which is around 8 percent richer in water, to form Madeira, the largest tributary of the Amazon.

Between the Bolivian city of Guayaramerín in the Beni department and the Brazilian city of Guajará-Mirim in the state of Rondônia on the east bank lies the 2.58 km² island of Isla Suárez , in Portuguese Ilha de Guajará-mirim . Their affiliation is controversial between the two countries. The administration is currently carried out by Bolivia.

navigability

The navigability of the Mamoré ranges from Chimoré at the foot of the Andes to a few kilometers before it joins the Rio Beni through the rapids there . The 380-kilometer Madeira-Mamoré Railway ends below the cataracts . Most of the tributaries are also navigable over longer distances.
