Rio Anauá is a remote and remarkably pristine tributary of the Rio Branco, flowing through the southern reaches of Roraima state in the northern Amazon basin. Positioned at the confluence where the Anauá meets the Rio Branco, this stretch of water represents one of the most lightly fished and well-preserved corners of the entire Amazon system. The river is flanked by dense rainforest and connects to a network of oxbow lakes and floodplain lakes that dramatically expand the fishable habitat. The combination of the river's main channel, its associated lakes, and the Rio Branco mainstem creates a multi-layered fishery that draws anglers seeking both explosive peacock bass action and the raw power of giant Amazonian catfish. The surrounding jungle remains largely intact, and the overall ecosystem reflects what much of the Amazon once looked like before significant human pressure — a rare and genuinely special destination for serious sport anglers.
