Beginning near South Fork Mountain in the western Cascade Range, the river flows generally north through Clackamas County to meet the larger river at Big Cliff. Most of the South Fork's drainage basin lies within the Mount Hood National Forest. The lower reaches of the river are part of the National Wild and Scenic Rivers System. Recreational opportunities in the basin include hiking, camping, and fishing for trout. A waterfall prevents salmon and other migratory fish from swimming upriver beyond the first .〔United States Forest Service, p. 2-29〕 ==Course== Originating near South Fork Mountain in the Cascade Range, the river runs generally north through rugged terrain in the Mount Hood National Forest. Near the headwaters, the river flows northwest, passing under Forest Road 4540, which parallels the river's left bank for about . At this point the river flows under Forest Road 45, a loop road that follows ridges to the left and right of the South Fork for much of the rest of its course.〔〔 Beyond Forest Road 45, the river turns to the northeast. At from the mouth, it receives the East Fork of the South Fork Clackamas River from the right. Further downstream, Oscar Creek enters from the right, then Memaloose Creek from the right only from the mouth. Shortly thereafter the river plunges over the South Fork Clackamas River Falls (or South Fork Falls) before joining the Clackamas River at Big Cliff, about from the larger river's confluence with the Willamette River.〔〔 The of the South Fork Clackamas River between the East Fork of the South Fork and the mainstem Clackamas River were designated "wild" in the National Wild and Scenic Rivers System in 2009.〔(【引用サイトリンク】 url = http://www.rivers.gov/wsr-clackamas-south.html )〕 Designated rivers are classified as either wild, scenic, or recreational depending on the degree of access and amount of nearby development.〔(【引用サイトリンク】 url=http://www.rivers.gov/q-and-a-answers.cfm?id=33 )〕 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「South Fork Clackamas River」の詳細全文を読む スポンサード リンク
