Great Slave Lake<ref name=CGNDBE>Template:Cite cgndb</ref>Template:Efn is the second-largest lake in the Northwest Territories, Canada (after Great Bear Lake), the deepest lake in North America at Template:Cvt,<ref name=EoEarth/> and the tenth-largest lake in the world by area. It is Template:Cvt long and Template:Cvt wide.<ref name="Distance Calculator"/> It covers an area of Template:Cvt<ref name=EoEarth/> in the southern part of the territory. Its given volume ranges from Template:Cvt<ref>Template:Cite journal</ref> to Template:Cvt<ref name=EoEarth/> and up to Template:Cvt<ref name="worldlake">Template:Cite web</ref> making it the 13th largest by volume.
The lake shares its name with the First Nations peoples of the Dene family called Slavey by their enemies the Cree. Towns situated on the lake include (clockwise from east) Łutselk'e, Fort Resolution, Hay River, Hay River Reserve, Behchokǫ̀, Yellowknife, Ndilǫ, and Dettah. The only community in the East Arm is Łutselk'e, a hamlet of about 350 people, largely Chipewyan Indigenous peoples of the Dene Nation, and the abandoned winter camp and Hudson's Bay Company post Fort Reliance. Along the south shore, east of Hay River is the abandoned Pine Point Mine and the company town of Pine Point.
History
Indigenous peoples were the first settlers around the lake after the retreat of glacial ice. Archaeological evidence has revealed several different periods of cultural history, including the Northern Plano tradition (8,000 years before present), Shield Archaic tradition (6,500 years), Arctic small tool tradition (3,500 years), and the Taltheilei Shale tradition (2,500 years before present). Each culture has left a distinct mark in the archaeological record based on type or size of lithic tools.<ref>W.C.

Great Slave Lake was put on European maps during the emergence of the fur trade towards the northwest from Hudson Bay in the mid 18th century. The name 'Great Slave' came from the English-language translation of the Cree exonym, Awokanek (Slavey), which they called the Dene Tha. The Slavey people were Dene tribes living on the lake's southern shores at that time.<ref>Waldman, Carl (2006). Facts on File Library of American History - Encyclopedia of Native American tribes.

In the 1930s, gold was discovered on the North Arm of Great Slave Lake. This discovery led to the establishment of Yellowknife, which would become the capital of the NWT. In 1960, an all-season highway was built around the west side of the lake; the highway was originally an extension of the Mackenzie Highway, but became known as Yellowknife Highway or Highway 3.Template:Cn
On 24 January 1978, a Soviet Radar Ocean Reconnaissance Satellite named Kosmos 954, which contained an onboard nuclear reactor, fell from orbit and disintegrated. Pieces of the nuclear core fell in the vicinity of Great Slave Lake. Some of the nuclear debris was recovered by a joint Canadian Armed Forces and United States Armed Forces military operation called Operation Morning Light.<ref>Template:Cite web</ref>
Suggested renaming
In the late 2010s, many placenames within the Northwest Territories were restored to their indigenous names. It has been suggested--particularly because of the mention of slavery--that the lake be renamed as well. "Great Slave Lake is actually a very terrible name, unless you're a proponent of slavery," says Dëneze Nakehk'o, a Northwest Territories educator and founding member of First Nations organization Dene Nahjo.<ref name="Up Here story">Template:Cite magazine</ref> "It's a beautiful place. It's majestic; it's huge. And I don't really think the current name on the map is fitting for that place." He has suggested Tu Nedhé, the Dene Soline name for the lake, as an alternative.<ref name="CBC renaming story">Template:Cite news</ref> Tucho, the Dehcho Dene term for the lake, has also been suggested.<ref name="Up Here story" />
Geography and natural history
The Hay, Slave (which in turn includes the Peace), Lockhart, and Taltson Rivers are its chief tributaries. It is drained by the Mackenzie River. Though the western shore is forested, the east shore and northern arm are tundra-like. The southern and eastern shores reach the edge of the Canadian Shield. Along with other lakes such as the Great Bear and Athabasca, it is a remnant of the vast glacial Lake McConnell.
The lake has a very irregular shoreline. The East Arm of Great Slave Lake is filled with islands, and the area is within the proposed Thaidene Nene National Park Reserve. The Pethei Peninsula separates the East Arm into McLeod Bay in the north and Christie Bay in the south. The lake is at least partially frozen during an average of eight months of the year.
The main western portion of the lake forms a moderately deep bowl with a surface area of Template:Cvt and a volume of Template:Cvt. This main portion has a maximum depth of Template:Cvt and a mean depth of Template:Cvt.<ref>Template:Cite web</ref> To the east, McLeod Bay (Template:Coord) and Christie Bay (Template:Coord) are much deeper, with a maximum recorded depth in Christie Bay of Template:Cvt.<ref name=EoEarth>Template:Cite web</ref>
On some of the plains surrounding Great Slave Lake, climax polygonal bogs have formed, the early successional stage to which often consists of pioneer black spruce.<ref>Template:Citation</ref>
South of Great Slave Lake, in a remote corner of Wood Buffalo National Park, is the Whooping Crane Summer Range, a nesting site of a remnant flock of whooping cranes, discovered in 1954.<ref>Template:Cite journal</ref>
Ecology
The Slave River provides the basin with high nutrient levels; accordingly, coupled with a general absence of pollution and invasive species, the lake is rich in aquatic life relative to its biome. Fish species include lake whitefish, lake trout, inconnu, northern pike and walleye, cisco, burbot, ninespine stickleback, shiner, also longnose sucker. Lake whitefish enjoy the highest levels, followed by cisco and suckers. Climate change, specifically reduced ice coverage times, is impacting the populations of these species. Copepoda are also prevalent in the lake.<ref>Ecosystem Model of Great Slave Lake to support an ecosystem approach to fisheries management nt.ca</ref><ref>Template:Cite web</ref>

Ice road
Great Slave Lake has one ice road known as the Dettah ice road. It is a Template:Cvt road that connects the Northwest Territories capital of Yellowknife to Dettah, a small First Nations fishing community also in the Northwest Territories. To reach the community in summer the drive is Template:Cvt via the Ingraham Trail.
In popular culture
Television
From 2014 to 2016, Animal Planet aired a documentary series called Ice Lake Rebels. It takes place on Great Slave Lake, and details the lives of houseboaters on the lake.<ref name="Animal Planet (Ice Lake Rebels)">Template:Cite web</ref>
Season 6 and season 7 of the survival game show Alone were set along the shore of the east arm of Great Slave Lake in the subarctic, about Template:Cvt south of the Arctic Circle and about Template:Cvt south of the tree line. It follows the self-documented daily struggles of 10 individuals as they survive alone in the wilderness for as long as possible using a limited amount of survival equipment.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
