Lake Hazen

Lake Hazen is often called the northernmost lake of Canada, in the northern part of Ellesmere Island, Nunavut, but detailed maps show several smaller lakes up to more than 100 km (62 mi) farther north on Canada's northernmost island. Turnabout Lake is immediately northeast of the northern end of Hazen lake. Still further north are the Upper and Lower Dumbell Lakes, with Upper Dumbell Lake 5.2 km (3 mi) southwest of Alert, Canada's northernmost settlement on the coast of Lincoln Sea, Arctic Ocean.[3]

The northeastern end of Lake Hazen is 118 km (73 mi) southwest of Alert. Lake Hazen is the largest lake north of the Arctic Circle by volume. By surface area, it is third largest, after Lake Taymyr in Russia and Lake Inari in Finland. Lake Hazen is 74 km (46 mi) long and up to 12 km (7 mi) wide, with an area of 537.5 km2 (207.5 sq mi).[1] It stretches in a southwest-northeast direction from 81°40′N 72°58′W to 81°56′N 68°55′W. The lake is up to 269 m (883 ft) deep and has an estimated volume of 51.4 km3.[2] The shoreline is 185 km (115 mi) long and 158 m (518 ft) above sea level. It has several islands, the largest of them being Johns Island, which is 7 km (4.3 mi) long and less than 1 km (0.62 mi) wide, also extending in a southwest-northeast direction like the lake itself. Other islands include Gatter Island, Clay Island (both close to the northeastern shore), Whisler Island, and Dyas Island (both close to the southern shore). The lake is covered by ice about ten months a year. It is fed by glaciers (most importantly Henrietta Nesmith and the Gilmour Glaciers) from the surrounding Eureka UplandsPalaeozoic rocks north of the lake, rising up to 2,500 m (8,200 ft) above sea level—and drained by 15 km (9.3 mi) long Ruggles River, which flows into Chandler Fjord on the northern east coast of Ellesmere Land. The lake is flanked by the Arctic Cordillera.

The area around the lake is a thermal oasis within a polar desert, with summer temperatures up to 20 °C (68 °F).[2]

The lake is part of Quttinirpaaq National Park.

Artifacts of Thule civilization were discovered near Lake Hazen in 2004.[4] Thule preceded the Inuit. In 1882, Adolphus Greely discovered the lake during his 1881–1883 expedition. Greely's base camp for the exploration was Fort Conger at the northeastern shore of Ellesmere Island, at 81°44′N 64°44′W, which was established as part of the first International Polar Year. Greely named the lake in honour of General William Babcock Hazen, who had organized the expedition.[1] Camp Hazen was established on the northern shore of the lake in 1957 during the International Geophysical Year (IGY), and has been used by various scientific parties since then.

Lake Hazen is populated by two morphotypes of Arctic char, a larger and a smaller. Studies in the 1990s indicated neither char morphotype is anadromous, but Inuit traditional knowledge states otherwise.[5]

Named Inflows

All named rivers and creeks are listed in a clockwise manner, starting in the south:

Tourism

Hikers can start their hiking trips at Lake Hazen itself, or from Tanquary Fiord warden station at Tanquary Fiord Airport 70 km (43 mi) southwest of the lake.

Retrieved 2020-05-14. “Two morphotypes of Arctic char are present in Lake Hazen: a large, cannibalistic form, and a small, presumably benthic-feeding form (Reist et al. 1995). Taken together, the results of both radiotelemetry studies in 1995–6 (Babaluk et al. in prep.) and, more conclusively, strontium uptake by char (Halden et al. 1996) suggest that neither form is anadromous. However, this is in contradiction to Inuit traditional knowledge, which holds that the char in Lake Hazen do go to sea (Ellesmere Island National Park Reserve Advisory Board, March 5, 1997). A comprehensive demographic analysis of the char population of Lake Hazen is in progress (J. Reist, pers. comm.). Fecundity information is still required.”
