It enters the Umatilla River about from the larger stream's confluence with the Columbia River. Birch Creek is one of the rivers that drain Oregon's northwestern corner of the Blue Mountains, flowing alongside industrial waste ponds, and over two minor impoundments before reaching the Umatilla River. Lands in the Birch Creek drainage are used for logging, grazing, dairy farming, and factory farming. Birch Creek is a source of phosphates and the resulting eutrophication of the Umatilla River. Pendleton photographer Walter S. Bowman is believed to have been born by Birch Creek. ==See also == *List of rivers of Oregon 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「Birch Creek (Umatilla River)」の詳細全文を読む スポンサード リンク
