Part of the system that provides drinking water to the city of Portland, it flows generally west through a protected part of the Mount Hood National Forest in Clackamas County. It joins the Bull Run River at Bull Run Reservoir 2, about from the larger stream's confluence with the Sandy River. ==Course== The river, which begins in Township Meadow in the Mount Hood National Forest, flows northwest and then west through Clackamas County and the Mount Hood National Forest. It receives its only named tributary, Cedar Creek, from the right before reaching a United States Geological Survey (USGS) stream gauge from the mouth. The South Fork joins the main stem Bull Run River at the larger stream's river mile (RM) 8 or river kilometer (RK) 13, near the midpoint of Bull Run Reservoir 2. 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 Bull Run River」の詳細全文を読む スポンサード リンク
