Paraguay River

The Paraguay River (Ysyry Paraguái in Guarani, Rio Paraguai in Portuguese, Río Paraguay in Spanish) is one of the important rivers in south-central South America. It flows through Brazil and Paraguay, and helps create parts of the borders between Paraguay-Argentina, Brazil-Bolivia, and Brazil-Paraguay.

The river travels a long distance of about 2,621 kilometres (1,629 miles). It starts in the Brazilian state of Mato Grosso and ends where it meets the Paraná River near the cities of Corrientes and Resistencia.

The Paraguay River is vital for the people and animals that live near it. It provides water for drinking, farming, and travel. Many towns and cities depend on the river for their everyday needs.

Course

The Paraguay River starts south of Diamantino in the Mato Grosso state of Brazil. It flows generally southwesterly, passing through Cáceres and the Pantanal wetlands, and then near Corumbá. It runs close to the border between Brazil and Bolivia.

From Puerto Bahia Negra in Paraguay, the river forms the border between Paraguay and Brazil, then flows almost due south until it meets the Apa River. It curves to the south-southeast before continuing southwest, dividing Paraguay into two parts: the western Gran Chaco region and the eastern forested areas where most people live. After passing through the center of Paraguay and the capital city, Asunción, the river forms the border with Argentina and finally joins the Paraná River.

Uses

The Paraguay River is an important river in South America. It is the second largest river in the Rio de la Plata Basin, after the Paraná River. Its drainage basin covers a large area including parts of Argentina, Brazil, Bolivia, and most of Paraguay.

Unlike some other big rivers, the Paraguay River has not been dammed for power. This means it can be used for travel over long distances, making it very important for shipping and trade. It helps connect landlocked countries like Paraguay and Bolivia to the Atlantic Ocean. The river supports cities such as Asunción and Concepción in Paraguay, and Formosa in Argentina.

The river also helps people by providing fish for food and work, and water for crops. Many families depend on the river for their living. However, sometimes the river floods, forcing people to leave their homes until the water goes down. The river is also a beautiful place for tourists to visit.

History

The original people who lived near the upper Paraguay River were the Guarani peoples.

In the 16th century, an explorer named Sebastian Cabot was the first European to discover the Paraguay River. Since then, the river has been very important, helping connect Paraguay to the rest of the world. Today, it is still used for moving goods on barges.

Wetland controversy

The Paraguay River flows through the Pantanal wetlands, the world's largest tropical wetland, covering parts of southern Brazil, northern Paraguay, and Bolivia. This important area depends on the river for its water.

In 1997, some countries wanted to change the river to make it easier to move goods, like soybeans, by building dams and changing the river's path. However, this could hurt the Pantanal and its wildlife. People worked to share information about these possible harms, which helped slow down the plans. Today, there is still discussion about how these changes might affect nature and the economy.

Water characteristics

The Paraguay River has many different kinds of places where the water looks and acts in special ways. Near a place called Bonito, the water is very clear, but farther down the river, near the Bermejo River, the water carries lots of mud and dirt.

The water in the Paraguay River changes a lot during different times of the year. In the dry season, the water is warm and cloudy, but in the wet season, it is cooler and clearer. The upper part of the river stays pretty warm all the time, usually never dropping below 22.5 °C (72.5 °F).

Fauna

The Paraguay River is home to many different kinds of fish, with around 350 species living there. Over half of these fish are small, colorful types like tetras, and others are catfish. Some fish travel up the river to lay their eggs, such as Prochilodus lineatus and Pseudoplatystoma corruscans.

The river shares some fish with the Amazon Basin, including the black phantom tetra, popular in aquariums, and the golden dorado, which people enjoy catching and eating.
