It flows from north to south and forms parts of the boundaries of Brazil, Argentina and Uruguay, separating some of the Argentine provinces of La 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 Ríos in Argentina; and makes up the western borders of the departments of Artigas, Salto, Paysandú, Río Negro, Soriano and Colonia in Uruguay. Etymology The name of the river tends to comes from the Spanish settlers’ interpretation of the Guaraní language word the inhabitants of the region used to designate it. There are several interpretations, including “the river of the uru (an indigenous bird)”, and “[river of] the uruguá” (an indigenous gastropod, Pomella megastoma).El País newspaper: Presentan tesis del nombre Uruguay {{Webarchive|url=https://web.archive.org/web/20120314100414www.elpais.com.uy/101008/pciuda-520474/informe/presentan-tesis-del-nombre-uruguay/ |date=14 March 2012 }}, {{in lang|es}} Retrieved 21 November 2014.

It is navigable from around Salto Chico. Its main tributary is the Río Negro, which is born in the south of Brazil and goes through Uruguay for 500 km until its confluence with the Uruguay River, which is located 100 km north of the Uruguay’s confluence with the Río de la Plata, in Punta Gorda, Colonia Department, Uruguay.The river is crossed by five international bridges called (from north to south): Integration Bridge and Paso de los Libres-Uruguaiana International Bridge, between Argentina and Brazil; and the Salto Grande Bridge, General Artigas Bridge and Libertador General San Martín Bridge between Argentina and Uruguay.The drainage basin of the Uruguay River has an area of {{convert|365000|km2|sqmi}}.BOOK, Varis, Olli, Tortajada, Cecilia, Biswas, Asit K., Management of Transboundary Rivers and Lakes, 2008, Springer, 978-3-540-74926-4,books.google.com/books?id=Z3ilzosWx4wC&pg=PA272, 272, Its main economic use is the generation of hydroelectricity and it is dammed in its lower portion by the Salto Grande Dam and by the Itá Dam upstream in Brazil. Cellulose plant conflict {{more citations needed section|date=May 2014}}Argentina and Uruguay experienced a conflict over the construction of pulp mills on the Uruguay River. Two European companies, ENCE and Botnia, proposed building cellulose processing plants at Fray Bentos, Uruguay, opposite Gualeguaychú, Argentina. According to a 1975 treaty, Argentina and Uruguay were supposed to jointly agree on matters relating to the Uruguay River.WEB, Helsingin Sanomat, Pulp mill dispute between Argentina and Uruguay intensifies,www.hs.fi/english/article/Pulp+mill+dispute+between+Argentina+and+Uruguay+intensifies/1135219507760, 26 May 2014, Argentina alleged that Uruguay broke the treaty. Additionally, Argentina believed the Finnish company Botnia was polluting the fish and the overall environment of the river while Uruguay believed that the plant was not depositing a large amount of toxins in the Uruguay River.WEB, Argentina y Uruguay ya esperan fallo de la CIJ en diferendo sobre pastera, AFP, Por Anna Pelegrí,www.google.com/hostednews/afp/article/ALeqM5gTc3ZWTskRnrf1J9zTNEuDtgSD1A, 10 February 2009, Starting in April 2005, residents of Gualeguaychú, as well as many others, protested, claiming that the plants would pollute the river shared by the two countries. Early in 2006, the conflict escalated into a diplomatic crisis,{{citation needed|date=May 2014}} compelling one of the companies move the project {{convert|250|km|mi}} south. Beginning in December 2005, the international bridges linking the Argentine province of Entre Ríos with Uruguay were intermittently blockaded by Argentine protesters, causing major disruptions in commercial traffic and tourism.In 2006, Argentina brought the dispute before the International Court of Justice. The ICJ completed hearings between Argentina and Uruguay regarding the dispute on October 2, 2009. In 2010, the court ruled that although Uruguay failed to inform Argentina of the construction of the pulp mills, the mills did not pollute the river, so closing the remaining pulp mill would be unjustified. Later in 2010, Argentina and Uruguay created a joint commission to coordinate activities on the river.
