Corrientes

South-west of Misiones there lies the province of Corrientes. It borders the countries of Paraguay, Brazil and Uruguay and, besides Misiones, the provinces of Entre Ríos, Santa Fe and Chaco. Before Spanish conquest, Corrientes was inhabited by the Kaingang, Charrua and Guaraní tribes. Later it served as an important stopover between the capitals of Buenos Aires and Asunción. The province has an area of about 88,000 km² and a population of about 1.2 million people. Its official languages are Spanish and Guaraní, being the first province of Argentina to officialize a language other than Spanish.

Corrientes is located between two rivers: the Uruguay River to the east, and the Paraná River to the northwest, the latter causing frequent floodings due to its low shores. The climate there is mostly subtropical with no dry season. Mean monthly temperatures range from 14°C in winter to 26°C in summer. Corrientes, like much of the Argentine north, has long had a relatively underdeveloped economy with agriculture being the largest contributor. Tobacco production alone accumulates almost half of the province's gross income.

Yacretá Dam
The Yacretá Dam is a hydroelectric power plant built over the waterfalls of Jasyretâ-Apipé in the Paraná River on the border of Argentina and Paraguay. It has a length of 808 m and has a maximum power output of 3,100 MW. Its construction was controversial due to its effects on the local ecosystem, causing the extinction in the wild of several species, and for going over budget.
