Productive areas are typically associated with specific types of structure. Confluences with smaller tributaries often create current seams and deeper holes that attract fish. Areas with submerged timber or fallen trees provide excellent ambush points for peacock bass and traíra. Undercut banks, particularly those with overhanging vegetation, are reliable spots, especially during lower light conditions. Deep pools at the base of riffles or runs are prime locations for holding larger catfish and bass.
