A peculiarity of the Orinoco river system is the Casiquiare canal, which starts as an arm of the Orinoco, and finds its way to the Rio Negro, a tributary of the Amazon, thus forming a 'natural canal' between Orinoco and Amazon.
Two large rivers that feed directly into the Amazon are the Rio Negro and the Madeira River. The Rio Negro meets the Amazon near Manaus, Brazil, while the Madeira River joins the Amazon in the western part of the Amazon Rainforest.
The three rivers that are close to Brazil's border are called the Paraguay, Parana, and Uruguay rivers. These rivers are located on the Triple Frontier.
