The stream also drains a small part of Clackamas County east of Tigard and south of Portland. | map1 = Oregon Locator Map.PNG | map1_size = 300 | map1_caption = Location of the mouth of Fanno Creek in Oregon | map1_alt = Fanno Creek is in northwestern Oregon. | map1_locator = Oregon | commons = }} Fanno Creek is a tributary of the Tualatin River in the U.S. state of Oregon.〔 Part of the drainage basin of the Columbia River, its watershed covers about in Multnomah, Washington, and Clackamas counties, including about within the Portland city limits. From its headwaters in the Tualatin Mountains (West Hills) in southwest Portland, the creek flows generally west and south through the cities of Portland, Beaverton, Tigard and Durham, and unincorporated areas of Washington County. It enters the Tualatin River about above the Tualatin's confluence with the Willamette River at West Linn. When settlers of European origin arrived, the Kalapuya lived in the area, having displaced the Multnomahs in pre-contact times. The first settler of European descent, Augustus Fanno, for whom the creek is named, arrived in the mid-19th century. He established an onion farm in what became Beaverton. Fanno Farmhouse, the restored family home, is a Century Farm on the National Register of Historic Places and is one of 16 urban parks in a narrow corridor along the creek. Although heavily polluted, the creek supports aquatic life, including coastal cutthroat trout in its upper reaches. Watershed councils such as the Fans of Fanno Creek and government agencies have worked to limit pollution and to restore native vegetation in riparian zones. ==Course== Fanno Creek arises at an elevation of above sea level and falls between source and mouth to an elevation of .〔〔 The main stem begins at about river mile (RM) 15 or river kilometer (RK) 24 in the Hillsdale neighborhood of southwest Portland, in Multnomah County. The creek flows west along the north side of Oregon Route 10 (the Beaverton–Hillsdale Highway), passing Albert Kelly Park and receiving Ivey Creek and Bridlemile Creek on the right before reaching the United States Geological Survey (USGS) stream gauge at Southwest 56th Avenue from the mouth. Shortly thereafter and in quick succession, it enters Washington County and the unincorporated community of Raleigh Hills, crosses under Route 10, and receives Sylvan Creek on the right. Here the stream turns south, passing through Bauman Park, where Vermont Creek enters on the left about from the mouth, and then southwest to flow through the Portland Golf Club and Vista Brook Park, where Woods Creek enters on the left. From here it flows west again for about , passing through Fanno Creek Trail Park and entering Beaverton about from the mouth before turning sharply south and flowing under Oregon Route 217 (Beaverton–Tigard Highway).〔〔〔〔 Fanno Creek then flows roughly parallel to Route 217 for about through Fanno Creek Park and Greenway Park. Near the southern end of Greenway Park, the creek passes under Oregon Route 210 (Scholls Ferry Road), and enters Tigard about from the mouth. In quick succession, Hiteon Creek enters on the right, Ash Creek on the left, and Summer Creek on the right before the creek reaches Woodard Park, goes under Oregon Route 99W (Southwest Pacific Highway), and flows through Fanno Park and Bonita Park as well as residential neighborhoods. Between the two parks, Red Rock Creek enters on the left about from the mouth. Slightly downstream of Bonita Park, Ball Creek enters on the left. Fanno Creek then enters Durham, passes a USGS gauging station from the mouth, flows through Durham City Park, and empties into the Tualatin River from its confluence with the Willamette River. 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「Fanno Creek」の詳細全文を読む スポンサード リンク
