It drains a remote area of the Cascade Range east of Sweet Home in the watershed of the Willamette River. It rises in the Cascades in eastern Linn County in the Willamette National Forest, about half a mile west of Iron Mountain. It flows briefly north, then generally west and southwest through the mountains and Middle Santiam Wilderness. In central Linn County it is impounded at the Green Peter Dam to form the Green Peter Lake reservoir. Approximately 4 mi (6 km) downstream from the dam it joins the South Santiam from the northeast as an arm of the Foster Lake reservoir. ==See also== *List of Oregon rivers *Willamette National Forest *Middle Santiam Wilderness 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「Middle Santiam River」の詳細全文を読む スポンサード リンク
