The Chetco River is a 56-mile-long (90 km) stream located in the southwestern portion of Oregon. It drains approximately 352 square miles (912 km2) of Curry County. Flowing through a rugged and isolated coastal region, it descends rapidly from about 3,200 feet (975 m) to sea level at the Pacific Ocean. Except for the lowermost 5 miles (8 km), the river is located entirely within the Rogue River – Siskiyou (SISK - you) National Forest.
