It drains part of the Cascade Range east of Eugene and flows westward into the southernmost end of the Willamette Valley. It is named for Donald Mackenzie, a Scottish Canadian fur trader who explored parts of the Pacific Northwest for the Pacific Fur Company in the early 19th century.〔McArthur, pp. 628–629〕〔Mackenzie, p. 91〕 In the 21st century, there are six large dams on the McKenzie and its tributaries.〔("About the McKenzie Watershed" ). McKenzie Watershed Council. Retrieved January 9, 2010.〕 ==Course== The McKenzie River originates as the outflow of Clear Lake in the high Cascades of eastern Linn County in the Willamette National Forest. (Clear Lake is fed by Ikenick Creek and Fish Lake Creek, the latter of which flows from Fish Lake. Fish Lake's main tributary is Hackieman Creek, which drains the north side of Browder Ridge east of Tombstone Pass. U.S. Route 20 crosses the pass and follows Hackieman Creek.) The McKenzie River flows south from Clear Lake, paralleled by Oregon Route 126, and goes over Sahalie and Koosah falls to Carmen Reservoir, where the river is diverted through a tunnel to Smith Reservoir.〔General course info from USGS topographic maps accessed via the "GNIS in Google Map" feature of the USGS Geographic Names Information System website; and 〕〔Sullivan, pp. 170–173〕 Between Carmen Reservoir and Tamolitch Falls, the riverbed is dry for because lava from Belknap Crater buried that stretch of the river about 1,600 years ago. The river flows under the lava for those three miles and re-surfaces at Tamolitch Pool at the base of Tamolitch Falls.〔 It then flows south into Trail Bridge Reservoir, where the Smith River enters from the right. After passing through Trail Bridge Dam, the river enters Lane County. The McKenzie continues south to Belknap Springs, where it turns west and flows past the community of McKenzie Bridge. It receives the South Fork McKenzie River about three miles east of Blue River. (The South Fork rises near the Pacific Crest Trail in the Three Sisters Wilderness and flows north-northwest for about through Cougar Reservoir and Cougar Dam.〔) After the South Fork confluence, the main stem of the McKenzie River continues west through a narrow valley in the mountains, receiving the Blue River from the north at the community named Blue River. The McKenzie then passes Vida and continues to Leaburg and Walterville. The McKenzie valley widens as the river continues west, receiving the Mohawk River from the northeast just north of Springfield. Emerging from the Cascade foothills, the McKenzie enters a broad floodplain. It joins the Willamette River from the east north of Eugene.〔〔Risley, ''et al.'', p. 4〕 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「McKenzie River (Oregon)」の詳細全文を読む スポンサード リンク
