Rio Negro (Amazon River Basin)

Context

One of the Amazon River's main tributaries has dropped to its lowest level ever recorded. The level of the Negro River at the port of Manaus is at 12.66 metres, compared to a normal level of about 21 metres.

About

The Rio Negro (Colombia) is one of the largest tributaries of the Amazon River and the largest blackwater river in the world.
The Rio Negro starts as the Guainía River and flows along the Colombian and Venezuelan border before crossing into Brazil where it becomes the Rio Negro.
The Negro River drains about 10 per cent of the Amazon basin and is the world's sixth-largest by water volume.
Manaus, the biggest city in the rainforest, is where the Negro joins the Amazon River.

Fact Box: Amazon River Basin

The Amazon River Basin is the world’s largest drainage system.
Coverage (countries): The basin occupies much of Brazil and Peru, and also parts of Guyana, Colombia, Ecuador, Bolivia, Suriname, French Guiana, and Venezuela.
The Amazon has over 1,100 tributaries, 17 of which are over 1,500 kilometres (930 mi) long.
Course: The Amazon River originates in the Peruvian Andes at an elevation of 5,598 meters. It begins as a small tributary called the Carhuasanta, located just 192 km from the Pacific Ocean.
- As it flows east, the river becomes the Hornillos, which merges into the Apurimac. This major tributary eventually connects with the Ene, Tambo, and Ucayali rivers.
- The Amazon descends steadily toward the Atlantic Ocean, dropping at a rate of 1.5 cm per kilometer over its 6,400 km course. In some sections, it expands to a width of 10 km and allows large ships to navigate up to Iquitos, Peru.
The Amazon Basin supports the world’s largest rainforest, which accounts for more than half the total volume of rainforests in the world.
Behind the Amazon, the next-longest river is the Yangtze River, which is only about 85 miles shorter than the Amazon.
