Qamanirjuaq Lake


Qamanirjuaq Lake formerly Kaminuriak Lake, pronunciation: ka-min-YOO-ree-ak; meaning: "huge lake adjoining a river at both ends", is a lake in the 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 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. Arctic explorer, Joseph Tyrrell, described the lake in his Geological Survey of Canada 1894 canoe expedition report:
Qamanirjuaq Lake is within the northern Hearne Domain, Western Churchill province of the Churchill Craton, northwest section of the Canadian Shield in northern Canada.
Ahimaa, a cave, once inhabited by an Inuk, is hollowed out of Qamanirjuaq Lake's massive cliff.

Qamanirjuaq caribou herd

The calving grounds of the large migratory Qamanirjuaq herd of barren-ground caribou are in the area surrounding Lake Qamanirjuaq, after which they are named. The herd returns annually after travelling an inconsistent, unpredictable 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.

Fish

In the mid 1970s, a fishery was moved from Kaminak Lake, 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 lichen, sphagnum, bryophytes, and a few dwarf birch.
