Kaminak Lake (pronounced: KA-min-ak) is a lake in Kivalliq Region, Nunavut, Canada. The sub-Arctic lake is one of eleven lakes of the Ferguson River system which ultimately flow into the northwestern Hudson Bay. The abandoned outpost of Tavani is 60 mi (97 km) to the east.
Around 1971, after reviewing 2,000 samples, the Geological Survey of Canada discovered: "an unusual and unsuspected distribution of above background mercury concentrations in natural waters". While this offered the potential for mineral explorations, it was also notable as commercial fishing occurs in Kaminak Lake. In the mid 1970s, the Kaminak Lake fishery was moved further up the Ferguson River to Qamanirjuaq ("Kaminuriak") Lake; it did not exhibit elevated mercury levels. Other prospecting and mapping studies followed and exploration companies found gold at the lake, including on an island within the lake.
Kaminak Lake is part of the barren-ground caribou migration area.
