The Chilkoot River is a river in Southeast Alaska, United States, that extends about from its source and covers a watershed area of . The source of the river is in the Takshanuk Mountains to the west and the Freebee glacier and unnamed mountains to the east. From its source, the upper reach of the river extends approximately to the point where it enters Chilkoot Lake. From the downstream end of the lake, the lower reach of the river flows for about until it enters the Chilkoot Inlet, a branch at the northern end of the Lynn Canal. At the head of the lower reach of the river, on the shore of the lake, lies a prehistoric village which was a Chilkoot Indian settlement. The names of the village — Tschilkut, Tananel, or Chilcoot — have been given to the river and also to the lake. The river and its precincts, known as the Chilkoot River Corridor, have been brought under the monitoring of the Chilkoot River Corridor Strategic Planning Project (CRC) to preserve its ecological and historical heritage.〔 A fishing weir has also been constructed on the river to monitor and count fish moving from the lake into the lower reaches of the Chilkoot River and the Chilkoot Inlet. ==Topography== The Chilkoot River near Haines has a short length of about from the source covering a watershed area of . The source of the river is in the Takshanuk Mountains to the west and the Ferebee glacier and unnamed mountains to the east. There are three stretches of the river from its source. These are: the "Upper Reach of the Chilkoot River" from the lake's mouth upstream to the glacier head, which is about ; the "Chilkoot Lake" fed by the upper reach of the river extends to about length followed by the "Chilkoot Lower reach", which is till it joins the Lynn Canal.〔river, pp.2–4〕 The Upper Chilkoot River originates from the glacier fields and flows in a southeasterly direction. It is a braided river and has a bed slope of 1 ft in 50 ft in the first stretch from the lake and about 1 ft in 100 ft in the balance reach of the river. The river is blocked with debris, rifles, log jams and boulders. Hence, the upper reach of the river is not navigable.〔 The upstream reaches of the Chilkoot River and all other streams which flow into the lake are barred for fishing.〔 The Chilkoot Lake, which forms the middle stretch of the Chilkoot River, is marked on the quadrant map of the Skagway B 2 USGS in the Heines County at an altitude of . The lake is about long (3.6 miles is also mentioned in one source), and about in width and maximum depth of water in the lake is about . It has been declared as navigable. The land around the lake () is mostly under the control of the State. The lake area is generally windy. Canoes are the best form of boating facility for fishing on the lake as the shore line is considered difficult.〔 The lower reach of the Chilkoot River below the outlet from the Chilkoot Lake at is 1.5 miles (a figure of is also mentioned in some sources} long till it meets the Lynn Canal of the Chilkoot Inlet. The river runs in northwest-northeast direction and is really only a small stream. It has a width of about and has a depth of on an average. It is navigable up to about upstream of the Lynn Canal, extending to the fish and game weir site (established by the Department of Fish and Game to enumerate the fishes), when under the influence of tides. The river, in its first one eighth mile (below the lake) has formed a pool, and then flows through a number of rapids strewn with boulders covered with moss in some stretches and the remaining part is flat but with rocky bed. The estimated average discharge in the river varies widely from a minimum of per second in February to a maximum of per second in August.〔〔 The river, the recreation area on the southern shores of the Chilkoot Lake and the Lake are approached by road along the Lukat-Chilkoot River Roads, also popularly known as the 'Bear Highway', as brown bears frequent this road in search of pink and coho salmon.〔Crupi, A. P. 2005. Brown Bear Research and Human Activity Monitoring at Chilkoot River, 2003-2004. Unpublished manuscript. 64 pp.〕 The Chilkoot Lake and the Chilkoot River outlet are about away from the town of Haines.〔 The river stretch is popular for coho fishing during September–October, pink salmon fishing during late July and August, and fish species of chum salmon, Dolly Varden and sockeye all through the summer and fall.〔 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「Chilkoot River」の詳細全文を読む スポンサード リンク
