Uruguay River

Uruguay River

This important South American river, which supports fishing and tourism, flows through the territories of Brazil, Uruguay, and Argentina before it joins the Río de la Plata. With a length of 1,600 kilometers and a basin measuring 370,000 kilometers, the Uruguay River rises 1,800 meters above sea level in the Serra Peral of Brazil and, along with the Paraná River, flows into the Río de la Plata (Argentina and Uruguay). From its source to the mouth of the Piratini River, the water is not very navigable, but it is possible for mid-draft ships to navigate up to the town of Concepción del Uruguay, Argentina, and for smaller crafts to travel to the town of Concordia, Argentina. There its course is interrupted by a large waterfall, which is the site of the Uruguay-Argentine hydroelectric power plant of Salto Grande, which began operations in 1983.

The Uruguay River is the border between the Brazilian states of Rio Grande do Sul and Santa Catarina, between Argentina and Brazil, between Argentina and Uruguay, and between Brazil and Uruguay. In the first decade of the twentieth century, Uruguay's plans to install two cellulose paste production plants at Fray Bentos, across from the Argentine town of Gualeguaychú, led to a diplomatic conflict between the two nations with an uncertain outcome.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
