Rio Formoso

Rio Formoso is a river flowing through Rondônia, Brazil. River fishing rewards anglers who learn to read current — fish hold in the seams between fast and slow water, behind rocks and submerged logs, and at the heads and tails of pools. At Rio Formoso, working a lure or fly down-and-across the current usually outperforms casting straight upstream. Higher water concentrates fish; clear, low water makes them spookier.

Fishing Techniques

• For Barred sorubim

  Target areas near submerged logs and deep holes, as Barred sorubim are ambush predators.

• For Vampire fish

  Use a wire leader to prevent bite-offs, as vampire fish have extremely sharp teeth.

• For Black pacu

  Black pacu are primarily herbivorous, so focus on presenting baits and lures that resemble fruits, seeds, or vegetation near structure or in areas with abundant plant life.
