Uruguay River

The Uruguay River is a river in South America. It flows from north to south and makes boundary with Brazil, Argentina and Uruguay, separating some of the Argentine provinces of the Mesopotamia from the other two countries. It passes between the states of Santa Catarina and Rio Grande do Sul in Brazil; forms the eastern border of the provinces of Misiones, Corrientes and Entre Rios in Argentina; and makes up the western borders of the departments of Artigas, Salto, Paysandu, Rio Negro, Soriano and Colonia in Uruguay.

The river measures about 1,500 km in length and starts in the Serra do Mar in Brazil, where the Canoas River and the Pelotas River are joined, at about 200 m above mean sea level. In this stage the river goes through uneven, broken terrain, forming rapids and falls. Its course through Rio Grande do Sul is not navigable.

Together with the Parana River, the Uruguay forms the Rio de la Plata estuary. It is navigable from around Salto Chico. Its main tributary is the Rio Negro, which is born in the south of Brazil and goes through Uruguay 500 km until its confluence with the Uruguay river, which is located 100 km north from the Uruguay's confluence with the Rio de la Plata, in Punta Gorda .

The river is crossed by four international bridges (from north to south): Paso de los Libres-Uruguaiana International Bridge, between Argentina and Brazil; and the Salto Grande Bridge, General Artigas Bridge and Libertador General San Martin Bridge between Argentina and Uruguay.

The basin of the Uruguay River has an area of 370,000 km. Its main economic use is the generation of hydroelectricity (see Salto Grande Dam).

Origin of the name

The name of the river comes from the Spanish settlers' interpretation of the word the locals used to designate it. The original name, ''Urugua'y'', in Guarani, means "river of the painted birds".

Cellulose plant conflict

Argentina and Uruguay are currently experiencing a conflict over the Uruguay River. Two European companies proposed to build cellulose-processing plants at Fray Bentos, Uruguay, opposite Gualeguaychu, Argentina. Since April 2005, residents of the latter as well as many others have protested, claiming that the plants will pollute the river shared by the two countries. At the turn of the year the conflict escalated into a diplomatic crisis, making one of the companies move the project 250 km south. Since December 2005, the international bridges linking the Argentine province of Entre Rios with Uruguay have been intermittently blockaded by Argentine protestors, causing major disruptions in commercial traffic and tourism.

Recent Developments

The International Court of Justice completed hearings on October 2, 2009, between Argentina and Uruguay over the dispute. Judges from the Court will present their verdict in the beginning of 2010. Argentina believes the Finnish company Botnia is polluting the fish as well as the overall environment while Uruguay believes that the plant is not depositing a large amount of toxins in the Uruguay River.
