Etymology

The name derives from the Dakelh (pronounced ákʰɛɬ/ Carrier people word meaning either 'top of small mountain' or 'small rock mountain on east side'. Cheslatta Lake appeared on Trutch's 1871 map of British Columbia as "Chestatta" Lake. In 1884, the spelling was changed to Cheslahta on Mohun's map of British Columbia. In 1891 the name was spelled as "Cheslata" Lake on Poudrier's map of Northern British Columbia. On 30 March 1917 the name "Cheslatta Lake" was adopted in the 15th Report of the Geographic Board of Canada based on the label on Jorgensen's 1895 map of BC, and as labelled on pre-emptor map 1G, 1916.

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
