The entirety of the Taraira River forms part of the international boundary that separates Amazonas state in Brazil from Vaupés Department in Colombia.

It flows Taraira River into the Apaporis River on the border (Brazil - Colombia)), where it discharges its waters, near (about 40 km (25 mi) following the course of the Apaporis) to Vila Bittencourt, a Brazilian settlement.

Taraira Lagoon, also known as Lake Caparú or Mosiro Itájura, is an old meander of the Apaporis River.

[5][6] To the east of the river is located an area corresponding to the Brazilian municipality of Japurá.
