The most productive areas are typically associated with specific types of structure. Deep pools, especially those with submerged timber or rocky bottoms, are prime locations for holding dorado and large bass. Confluences where smaller streams enter the main arroyo often create current seams and oxygenated water that attract fish. Areas with undercut banks and overhanging vegetation provide shade and cover, making them reliable spots for Trahira and bass. Fishing the edges of faster runs and riffles can also be productive for actively feeding fish.
