The Río Itaú is a river in southern Bolivia and northern Argentina . It runs about 88 kilometers on Bolivian territory ( Departamento Tarija ) and represents the border with Argentina ( Salta province ) for the remaining 74 kilometers . It flows through a valley between two of the mountain ranges that run strictly north-south in this region the folding of the Andes to the east.
course
The Río Itaú rises about 80 kilometers east of the city of Tarija in the Serranía Suaruro in the Voranden at an altitude of 1880 m in the extreme west of the Gran Chaco province . It flows through a sparsely populated valley between the Serranía Suaruro and the Serranía Itaú to the south, past its namesake, the village of Itaú , and meets the Ruta 33 , which runs from here on its western bank. After 88 kilometers it reaches the state border and from here marks the border between the two countries. At the places Madrejones on the Argentine, and San Antonio on the Bolivian side, the Río Tarija reaches the Río Itaú from the west in a deeply cut valley through the Serranía Alto las Cañas . Together they flow further south as the Río Grande de Tarija , where it flows into the Río Bermejo .
Due to the seasonally strongly fluctuating rainfall of the northwestern Chaco and the therefore also strongly season-dependent water level, the Río Itaú has a wide river bed, especially on its lower reaches, in which it meanders in the dry season , but which can swell significantly in the rainy season.
Despite the development by a trunk road, the Bolivian side of the Río Itaú is only sparsely populated, on the Argentine side there are no significant settlements due to the lack of road connections.
