Desaguadero

The Desaguadero river is an Argentine river. The river Bermejo or Vinchina originates near the Tipas volcano in La Rioja at an elevation of around 5,500 meters. Its upper stages are known as the Bermejo or Vinchina. It is also known as the Salado in its lower reaches. In La Pampa Province, near Pichi Mahuida, it meets the Colorado River. The Desaguadero River has a total length of 1,498 kilometers and a drainage basin of approximately 260,000 square kilometers.

It is one of the key rivers that supply Cuyo's irrigated lands, and it flows along the region's eastern border. Despite its length, the river is a small, shallow stream for most of the year due to irrigation use, and surface flow only reaches the Colorado on rare occasions. The Jáchal, San Juan, Tunuyán, Diamante, and Atuel Rivers are tributaries. The river served as a traditional boundary between the viceroyalty of Buenos Aires and the viceroyalty of Peru.
