Rio Arinos

As a river in Mato Grosso, Brazil, Rio Arinos fishes best when the flow is steady and the water is clear enough to see a foot or two down. Anglers who do well at Rio Arinos pay attention to small things: the angle of the current, the colour of the water, what's hatching, where the wading birds are working. Fly anglers can match local insect activity; spin anglers can run small spinners or soft plastics through the same lies.
