Wikipedia description:
The Rio Negro (Spanish: Río Negro [ˈri.o ˈneɣɾo], Portuguese: Rio Negro [ˈʁi.u ˈneɡɾu], "Black River"), or Guainía as it is known in its upper part, is the largest left tributary of the Amazon River (accounting for about 14% of the water in the Amazon basin), the largest blackwater river in the world, and one of the world's ten largest rivers by average discharge. It originates in the tepuis of the department of Guainía, Colombia, and then flows southeastward before finally entering Brazil. Despite its high flow, the Rio Negro has a low sediment load (5.76 million tonnes per year on average in Manaus).
