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. 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
