Lac de Gras is a lake approximately 300 kilometres (190 mi) north of Yellowknife, in the Northwest Territories of Canada. Lac de Gras was the centre of the diamond rush of the 1990s. There are three working diamond mines in the area, Diavik Diamond Mine, Ekati Diamond Mine, and Snap Lake Diamond Mine.[2][3]

It was called Ekati by aboriginal peoples. It is 60 kilometres long, with an average width of 16 kilometres and 740 kilometres of shoreline. It has a maximum depth of 56 metres. Native fish species include lake trout, cisco, common whitefish, Arctic grayling, burbot, longnose sucker, and slimy sculpin.
