Arroyo Blanco is a stream tucked within the Chubut province of Argentine Patagonia, situated near the town of Esquel at approximately 43°01′S, 71°49′W. This remote Patagonian waterway flows through a landscape shaped by the dramatic geography of the Andean foothills, placing it in excellent company alongside some of the region's most celebrated trout fisheries. The stream exists in two recognized sections — Arroyo Blanco Norte and Arroyo Blanco Sur — each offering its own character within the broader Chubut watershed. Neighboring waters such as Lago Futalaufquen, Lago Rivadavia, Río Tigre, and Río Azul speak to the richness of the surrounding fishery, and Arroyo Blanco fits naturally into any multi-day Patagonian fishing itinerary centered on the Esquel area.
