It flows through the Fremont–Winema National Forests, Bureau of Land Management land, and private property in southern Oregon. Its watershed consists of of conifer forest, marsh, and rural pasture land. The river provides habitat for many species of wildlife including native Great Basin redband trout (''Oncorhynchus mykiss newberri'') a subspecies of rainbow trout. == Course == The Chewaucan flows for through Lake County, Oregon.〔 The sources of the Chewaucan are Elder Creek and Dairy Creek. Both have their headwaters in the east drainage of the Gearhart Mountain. The Chewaucan is the result of their merger east of the Gearhart Mountain Wilderness near Dairy Point. From there, the Chewaucan flows north through the Fremont-Winema National Forests where waters from Ben Young Creek, Coffeepot Creek, Antelope Springs, Corral Creek, Dog Creek, Sage Hen Creek, Bear Creek, and Mill Creek flow into it before the river passes out of the forest near Paisley.〔 The relevant quadrangles from source to mouth are Shoestring Butte, Morgan Butte, Paisley, Coglan Buttes, Tucker Hill, and Coglan Buttes SE.〕 The Chewaucan flows through Paisley and into what was once the ''Upper Chewaucan Marsh'' east of the town. The marsh is now pasture land, and the river’s flow through this area is controlled by a system of weirs and irrigation canals. The river is consolidated for a short distance as it leaves the upper marsh at ''The Narrows'', where two fingers of high desert uplands force the river into a single narrow channel. The river then opens into the ''Lower Chewaucan Marsh'' approximately northwest of Valley Falls. Finally, Crooked Creek joins the Chewaucan just one mile (1.6 km) before it empties into Abert Lake, which has no outlet.〔 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「Chewaucan River」の詳細全文を読む スポンサード リンク
