Río Colorado is a stream flowing through the Maule Region of Chile, situated at approximately 35°16′S, 71°00′W. The Maule Region is renowned among anglers for its diverse trout fisheries, and Río Colorado sits within a broader network of productive waters that includes well-known destinations such as Lago Colbún, Río Achibueno, and Laguna del Maule. As a stream-type water body in this part of central Chile, it exists within a landscape shaped by the Andes and the transition zone between the Andean foothills and the Central Valley, a geography that typically produces cold, clear freestone streams well-suited to trout.
