Productive areas include the confluence zones where Ribeirão Formoso meets larger rivers, as these create current seams and nutrient-rich environments that attract baitfish and predators. Isolated lagoons and oxbows accessible from the main channel are prime locations for large peacock bass, especially during the wet season when they move into these flooded areas to feed. Undercut banks with overhanging vegetation and submerged timber piles are consistently reliable spots.
