 River network with the Río Orthon in the Beni lowlands |
||
The Río Orthon is a river in the northern lowlands of Bolivia , which is formed by the confluence of the Río Tahuamanu (main source river) and Río Manuripi near the rural city of Puerto Rico and belongs to the river system of the Amazon . Its catchment area covers 33,725 km², of which 19,516 km² is in Bolivia.
course
The Río Orthon has its origin on the northern edge of the national reserve "Reserva Nacional La Vida Silvestre Amazónica Manuripi" in the province of Manuripi and forms the border with the province of Abuná in the Pando department of Bolivia, which is further north . From the confluence of the Tahuamanu and Manuripi rivers, the river runs in an easterly direction and flows into the Río Beni after 410 km , which after the confluence with the Río Mamoré reaches the Amazon as the Rio Madeira . Río Tahuamanu and Río Orthon have a total length of 1310 km.
Due to its low gradient of only 50 meters to 410 km meanders of the river very strong and changed so again its course and its length, especially when touching two adjacent loops, the water takes the resulting shortcut and so Backwater remain, which silt up with time. Since the river runs through tropical rainforest throughout its entire course and has so far not been well developed for traffic, its catchment area is largely deserted. The only traffic route for developing the region along the river is the waterway, road connections only exist at the confluence near Puerto Rico and further down the Río Madre de Dios.
history
Except for the local population, the river was not known until 1880 through the North American Edwin Heath , who gave it the name of his colleague and compatriot James Orthon . The river was known by the local peoples as " Datimanu " and as the "River of the Petas", an aquatic turtle found there.
