Suriname

Suriname does not have a determined drainage area of the Amazon Basin. One of the goals of the GET Amazonas Project is to define this area, which may represent between 0.05% and 0.1% of the total area of the basin and from 1% to 2% of the territory of the country. The main basins flow into the Atlantic, such as the basins of Rivers Tapanahony and Litani. The rivers that flow into the Amazon still need to be defined.

Venezuela

Venezuela has a drainage surface of the Amazon Basin of 42,784 km2, which represents about 0.7% of the total area of the basin and 4.7% of the Venezuelan territory. Its main basin is the Negro river basin.
