La Plata Basin

The Río de la Plata Basin (Spanish: Cuenca del Plata, Portuguese: Bacia do Prata), sometimes called the Platine basin[1] or Platine region,[2] is the name given to the 4,144,000 square kilometres (1,600,000 sq mi)[3] hydrographical area that covers parts of Argentina, Brazil, Bolivia, Paraguay and Uruguay. It is one of the largest river basins on Earth.

The precipitation falling within this area is collected by several rivers to finally reach the Río de la Plata (or River Plate; River of Silver in Spanish), many of them through the Paraná River and the Uruguay River, its two most important tributaries. These rivers include the Paraguay, Pilcomayo, Bermejo, Salado, Carcarañá, Tercero, Tietê, Cuarto, Iguazú, Salado del Sur, Gualeguay, Nogoyá, Mocoretá, Gualeguaychú, Miriñay, Aguapey, Negro, Guaycurú, San Javier, Guayquiraró and Samborombón.[4]


There are several hydroelectric dams operating in the basin, among them, the Rincon del Bonete or Gabriel Terra Reservoir on the Rio Negro in Uruguay. Further down the river the Baygorria Dam and the Constitution Dam at Palmar. The Salto Grande Dam is on the Uruguayan river on the border between Uruguay and Argentina.[5]
