Course with tributaries

The Río Madre de Dios ( Spanish for “Mother of God River”; Quechua : Amaru Mayu - “River of the Sacred Serpent”; Araona : Manutata - “Father of the Rivers”) is a left tributary of the Río Beni in southeastern Peru and northern Bolivia .

Its headwaters are in the very rainy Cordillera Carabaya in the Madre de Dios department . The total of almost 1400 km long Río Madre de Dios has at its mouth with 6372 m³ / s a ​​larger water flow than the Río Beni with 2829 m³ / s and this in turn a larger water flow at the confluence with the Río Mamoré , so that the hydrological Main strand of the Rio Madeira runs.

Source rivers

The river takes its name from the confluence of the Río Alto Madre de Dios and the much larger Río Manú near the town of Puerto Manú .

Río Alto Madre de Dios

The Río Madre de Dios rises as Río Huaisampilla together with tributaries of similar size in the Cordillera de Carabaya (Nevado de Pucará). The sub-Andean marginal chains that accompany the foot of the mountain in the east lead to the early unification of the watercourses directed transversely to them and are finally broken by them in ravines. After passing the gorge of the Pongo de Coñec , the Río Alto Madre de Dios flows almost in a straight line to the northeast in a branched, gravel-rich river bed, following the gentle slope of the gently rolling Andean foothills. At the confluence with the Río Manú, it has an average of around 570 m³ / s of water. The length of the river is about 250 kilometers.

Río Manú

The upper Río Manú (Araona: "river") flows northwards from its headwaters in the Andean marginal chains, which are covered by dense foggy and mountain rainforests , and then swings strongly meandering to the southeast. From the right it receives most of the tributaries, of which the Río Providencia and the Río Pinquina are the largest. The largest part of its exceptionally species-rich catchment area is protected in the Manú National Park and may not be entered in the extensive core zone. With an average water flow of around 920 m³ / s at the mouth, the Manú represents the actual upper reaches of the Río Madre de Dios hydrologically , which also maintains the direction of the Manú. The length information ranges from 356 km to a more plausible 465 km.

Course as Madre de Dios

Below Boca de Manú, the Río Madre de Dios gradually swings from its south-eastern flow direction, which is initially parallel to the Andes, to the northeast, the main direction of the rivers in the southern Amazon basin . The first of numerous right tributaries, the Río Azul, flows out at Puerto Tahuantinsuyo. A little later, the Río Colorado flows into the upper reaches of which large areas are almost devastated as a result of largely illegal gold mining, and whose water has a high level of mercury. The largest tributary is the Río Inambari , which comes from the Andean marginal chains, and the longest is the Río Las Piedras, which flows from the left . Opposite in the confluence of the Río Tambopata lies the only important city on the Río Madre de Dios, Puerto Maldonado , capital of the Madre de Dios region and a commercial center with a small airport. The city officially bears the title: Capital de la Biodiversidad del Perú (Biodiversity Capital of Peru). From here the river is also called Bajo Madre de Dios (Lower M.).

After almost 460 kilometers, the Madre de Dios reaches the border to Bolivia in the small town of Puerto Heath . It continues to flow northeast, a direction that the current maintains under other names as far as the Amazon. After a further 483 kilometers of the river, it joins the Río Beni at Riberalta . The river meanders along its entire length and therefore changes its course and length constantly. Numerous oxbow lakes accompany its course.

In some maps, the 160 km long stretch of river between Riberalta and the mouth of the Río Beni is also referred to as the Río Madre de Dios , but official Bolivian maps show it as the Río Beni .

The Río Madre de Dios is the main artery of an otherwise very little developed area, interrupted, however, by smaller rapids. Little land is cultivated on its banks, mainly as subsistence agriculture and for mango cultures . The Bahuaja Sonene National Park and the Tambopata-Candamo National Park have also been established on the southern Peruvian tributaries .
