Qamanirjuaq Lake (variant: Kaminuriak Lake; pronunciation: ka-min-YOO-ree-ak; meaning: "huge lake adjoining a river at both ends")[3] is a lake in Kivalliq Region, Nunavut, Canada. It is the first of several named lakes on the eastward flow of the Ferguson River through the eastern barrenlands. The lake is located about 1 mile (2 km) downstream from Ferguson Lake, and adjacent upstream to Parker Lake South. The Ferguson River passes through a series of rapids before entering the western arm of Qamanirjuaq Lake.
Geography
The lake is irregularly shaped with several inlets and unnamed islands, in a permafrost area of north-northwest ice flow, north of the tree line[4] Canadian Arctic explorer, Joseph Burr Tyrrell, described the lake in his Geological Survey of Canada 1894 canoe expedition report:
- "Kaminuriak Lake is a beautiful sheet of clear cold water lying in the till-covered plain... Where seen, the beach is in some places sandy, but more generally of large boulders, which, on the more exposed parts of the shore are arranged in a regular wall to the height of from eight to twelve feet, while in the bays they are scattered over a shallow floor of sand or till. Back from the lake the country stretches in wide treeless plains, or rises in low grassy hills, which show no signs of any underlying rock... Following the south shore of Kaminuriak Lake to its southeastern angle, the river was again reached... now a much larger stream, sixty yards wide and two feet deep."[5]
Qamanirjuaq Lake is within the northern Hearne Domain, Western Churchill province of the Churchill craton, northwest section of the Canadian Shield in northern Canada.
The Ahimaa Cave (Inuktitut: "are you other?" or "are you other being?"), once inhabited by Inuit, is hollowed out of Qamanirjuaq Lake's massive cliff.[6]
Fauna
This habitat is hospitable to Qamanirjuaq barren-ground caribou, the namesake of the lake, who consider the area surrounding the lake as their traditional calving grounds, returning annually after travelling an inconsistent, unpredictable 500 miles (805 km) range through Manitoba/Nunavut, northeastern Saskatchewan, and southeastern Northwest Territories. The herd, a keystone species, has been safeguarded by the Beverly and Qamanirjuaq Caribou Management Board since 1982.[7]
In the mid 1970s, a fishery was moved from Kaminak Lake (which proved to have unacceptably high levels of Mercury), to Qamanirjuaq Lake which showed no elevated Mercury levels. The lake is filled with lake whitefish and lake trout for commercial fishing, and is also home to Lasallia pensylvanica Arctic lichen, sphagnum, bryophytes, and a few dwarf birch.[8][9][10][11][12][13]
