Finally, it empties into the Pacific Ocean between the cities of Brookings and Harbor. The watershed is located completely within Curry County. | commons = }} The Chetco River is a stream located in the southwestern portion of the U.S. state of Oregon. It drains approximately of Curry County. Flowing through a rugged and isolated coastal region, it descends rapidly from about to sea level at the Pacific Ocean. Except for the lowermost , 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 north of the California state line. The Chetco River's watershed remains largely undeveloped, protected by the Rogue River – Siskiyou National Forest and the Kalmiopsis Wilderness. The upper of the river have been designated Wild and Scenic since 1988. Native Americans have lived in the Chetco River's watershed for the last one to three thousand years. Several explorers, including Sir Francis Drake, George Vancouver, and Jedediah Smith, visited the region between the 16th and 19th centuries, and found the Chetco people inhabiting the area. Non-indigenous settlers arrived soon after gold and other precious metals were discovered in the 1840s and 1850s. The town of Brookings was founded in the early 20th century, and incorporated in 1951. Fourteen thousand residents of Brookings and Harbor rely on the Chetco for drinking water. Supporting a large population of salmon and trout, the Chetco's water is of very high quality. The watershed is home to many other species, including several that are endemic to the Siskiyou Mountains area. The northernmost grove of Redwoods—the tallest trees on Earth—grow in the southern region of the Chetco's drainage basin. In total, the river is home to over 200 species of animals, and 97 percent of the watershed is forested. ==Course== The Chetco River begins about east of Chetco Peak, approximately above sea level. It flows north, gathering small tributaries such as the Little Chetco River and Babyfoot Creek. The river turns west near the Pearsoll Peak, the highest point in the watershed. It receives Box Canyon Creek on the left bank, Tincup Creek on the right bank, and Boulder Creek on the left. It then flows south, gathering the South Fork Chetco River. A few miles farther south, the river passes through a Redwood grove. It flows between Bosley Butte to the north and Mount Emily to the south; the latter is the impact site of one of only four bombs known to have been dropped in the continental United States by an enemy aircraft. This occurred during the Lookout Air Raids of 1942. Turning southwest, the river flows through Alfred A. Loeb State Park and collects the North Fork Chetco River on the right at river mile (RM) 5 (or river kilometer (RK) 8). The Chetco becomes an estuary about from its mouth. It passes through the communities of Brookings to the north and Harbor to the south, and discharges into the Pacific Ocean. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chetco River」の詳細全文を読む スポンサード リンク
