Productive areas include the confluence zones where smaller tributaries enter the Rio Tesouro, bringing in nutrients and creating current breaks that hold fish. Deep pools adjacent to faster riffles and runs are reliable spots for larger trout and dourado. Areas with significant underwater structure, such as submerged logs, rock ledges, and undercut banks, consistently hold predatory fish. The sections of river near rapids and waterfalls are prime locations for targeting aggressive dourado.
