Prime fishing locations are found at the confluence of significant tributaries, which often create nutrient-rich seams and deeper holding water. The area immediately downstream of the Lago Riñihue outlet is a renowned spot, where lake-run fish can enter the river. Deep pools adjacent to undercut banks, logjams, and large boulders are consistently productive throughout the river system. The tail-outs of long riffles, where the current slows and depth increases, are also excellent spots to find feeding trout.
