The Amazon basin is the largest drainage basin in the world , with an area of approximately 7,050,000 square kilometres ( 2,720,000 sq mi ) . The portion of the river 's drainage basin in Brazil alone is larger than any other river 's basin . The Amazon enters Brazil with only one - fifth of the flow it finally discharges into the Atlantic Ocean , yet already has a greater flow at this point than the discharge of any other river . </P>
