Part of the system that provides drinking water to the city of Portland, it flows generally northwest through a protected part of the Mount Hood National Forest in Clackamas and Multnomah counties. It joins the Bull Run River at the upper end of Bull Run Reservoir 1, about from the larger stream's confluence with the Sandy River. ==Course== The creek arises in the Mount Hood National Forest in northern Clackamas County near its border with Multnomah County. The stream flows north, crossing the border almost immediately and entering Multnomah County. Turning west, it receives an unnamed tributary from the right before turning gradually northwest. It passes under Forest Road 1211 and by a United States Geological Survey (USGS) stream gauge from the mouth. The creek joins the main stem Bull Run River near the upper end of Bull Run Reservoir 1, about from where the river joins the Sandy 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「Fir Creek (Bull Run River)」の詳細全文を読む スポンサード リンク
