The Klamath River is a river in southern Oregon and northern California in the United States. This article describes its course. ==Oregon== The Klamath River's drainage basin above Upper Klamath Lake is fed primarily by the Williamson River and the Sprague River, which stretch into south-central Oregon west of the Cascades. The official beginning of the long river is at the outlet of Upper Klamath Lake, a large and artificially expanded lake east of the Cascade Range. Above Upper Klamath Lake, several rivers and streams drain south from Crater Lake and the southeast Cascades to form Agency Lake, which is connected to Upper Klamath Lake. After flowing out of the Bureau of Reclamation-built dam, the river flows into a stretch known as the Link River, past the city of Klamath Falls and into Lake Ewauna, a -long reservoir. The Lost River enters from the left via a series of agricultural ditches and canals (formerly, all of its water emptied into Tule Lake). It crosses under Oregon State Route 97 twice, once upstream of and once downstream of Oregon Route 140, and continues west through an agricultural valley to Keno. At Keno the river veers sharply south and passes through the Keno Dam, which forms Lake Ewauna, from the mouth, passing the now-drained Lower Klamath Lake.〔BEST and WSTB, p.27〕 The Klamath enters a narrow gorge and runs northeast, then enters the J.C. Boyle Reservoir, formed by the John C. Boyle Dam, and passes through the gates of the dam from the mouth. After flowing out of the rockfill structure, the river heads south and plunges rapidly into a narrow and deep gorge about deep and wide. After flowing a few miles through this narrow gorge, it widens into a rugged valley and turns west-southwest, crossing the Oregon-California border. Butte Creek comes in from the south. After crossing the border, the river turns sharply south, diverges around a small island, and receives Edge Creek from the right. The river then flows into Copco Lake, formed by the Copco Dam. Exiting the dam from the mouth, the river bends sharply north then south around a ridge and receives Fall Creek from the right as it passes the town of Copco.〔〔 There are proposals to remove all four dams by 2020. 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「Course of the Klamath River」の詳細全文を読む スポンサード リンク
