The Construction of the
Kenny Dam in the 1950s on the Nechako River, reversed water flow and sent water westward to generate electricity for use and sale by the Alcan corporation, devastated the area around Cheslatta Lake, flooding the
Cheslatta Carrier Nation village and cemetery and forcing the First Nations to be relocated with little time for preparation and no consultation. Prior to the flooding, Cheslatta Lake was at the centre of the CCN traditional hunting and trapping territory. Before 1957 the Cheslatta River was a small stream with an average annual flow of about . Alcan began releasing water flows far above the Cheslatta's natural capacity, resulting in a deep channel being carved out and large-scale erosion filling the Cheslatta and upper Nechako Rivers with sediment. In addition, the area between the
Skins Lake spillway and the headwaters of the Cheslatta River was not a river but rather a series of meadows, pastures, and small lakes. Water released from the reservoir scoured the area between Skins Lake and Cheslatta Lake. Soil, gravel, grass, moss, shrubs, and trees were washed away, down into the Cheslatta River and into the Nechako River. There has been a 7-fold decline in the productive capacity of Cheslatta Lake to support
pelagic fishes, namely
kokanee salmon. ==See also==
