High Quality Content by WIKIPEDIA articles! The Chetco River is a 56-mile-long (90 km) stream located in the southwestern portion of the U.S. state 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 (980 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 National Forest. The river rises in the Kalmiopsis Wilderness, northwest of Chetco Peak at the junction of the Oregon Coast Range and the Klamath Mountains. It flows generally north, west, and then southwest, before emptying into the ocean between Brookings and Harbor, approximately 6 miles (10 km) north of the California state line.
