Rio Negro (Argentina)

Negro River means black river, and is the most important river of the Argentine province of Rio Negro.

It originates from the junction of the Limay River and Neuquen River at the border with the Neuquen Province, and flows southeast to the Atlantic Ocean, near El Condor beach resort some 30 kilometres downstream from Viedma, Rio Negro province's capital.

The river allows the Rio Negro province to produce 65% of the pears and apples of Argentina. Besides irrigation, the river is also source of hydroelectricity with small dams on its course.

The river served as natural demarcation between "civilisation" and the aboriginal territories during the Conquest of the Desert of late 19th century.


The river is divided into three parts: The Alto Valle (High Valley) near the beginning of the river, Valle Medio (Medium Valley) near Choele Choel, and Valle Inferior (Inferior Valley) near its end.

The river crosses the rainforeststeppe plains of the province through jungles of around three kilometres in the Alto Valle, and as wide as 20 kilometres towards the Valle Inferior. In the dense jungle it is possible to find seashells and petrified monkeys.

Alto Valle

The main cities in Alto Valle are: Ganeral Rocu, Cipolletti, Villa Reginaria, followed by many others on the National Route 22. Together with San Carlos de Bariloche, this is the most prosperous part of the province. Most pear and apple plantations are at the Alto Valle, but many also at the Valle Medio.

Valle Medio

Next to Choele Choel is the Choele Choel Island, in which are Lamarque, Luis Beltran and Pomona, all of them on National Route 250.

Besides apple and pear cultivation, tomato is also an important crop, being Lamarque the National Capital of the Tomato. Outside the valley, on the more arid lands around town such as Chimpay and Darwin, some cattle is also raised.

Valle Inferior

Although the term is not as used term as the previous two, Valle Inferior refers to Viedma and all the cities on the province's coast. Fruit is also produced but is not a primary activity. Onion is cultivated as well as some cereals. Alfalfa and maize is cultivated both for human consumption and for feeding cattle, which is the most important activity.


In spite of its name of Negro ("black") the colour is more greenish than black. Nevertheless, the name is the literal translation of its aboriginal Mapuche name of Curu Leuvu. The river was also known by the name of Rio de los Sauces ("River of Willows") for the abundant weeping willows at its shores.


The Regata del Rio Negro (Black River Regatta), run in this river, is the longest kayak boat-race in the world with its 653 kilometres. The competition is divided in 6 stages and last 8 days (2 days for rest).
