The Nelson River Hydroelectric Project refers to the construction of a series of dams and hydroelectric power plants on the Nelson River in Northern Manitoba , Canada. The project began to take shape in the late 1950s, with the planning and construction of the Kelsey dam and hydroelectric power station, and later was expanded to include the diversion of the upper Churchill River into the Nelson River and the transformation of Lake Winnipeg , the world's 11th largest freshwater lake, into a hydroelectric reservoir . The project is owned and operated by Manitoba Hydro , the electrical utility in the province.

120-581: Several sites on the Nelson River, with potential of millions of horsepower, had been identified as early as 1911, but transmission of power to population centres in the south was beyond the state of the art of electric power transmission at that time. Between 1955 and 1960, studies were carried out to determine what resources would be available for future hydraulic generation in Manitoba. The stations at Kelsey, Kettle, Long Spruce and Limestone were built on

240-461: A okimahkan . loosely translated as "war chief". This office was different from that of the "peace chief", a leader who had a role more like that of diplomat. In the run-up to the 1885 North-West Rebellion , Big Bear was the leader of his band, but once the fighting started Wandering Spirit became war leader. There have been several attempts to create a national political organization that would represent all Cree peoples, at least as far back as

360-549: A suture zone between these cratons and the Trans-Hudson Orogen . The Western Churchill and Superior cratons collided at about 1.9–1.8 Ga in the Trans-Hudson orogeny. Because of the irregular shapes of the colliding cratons, this collision trapped between them large fragments of juvenile crust, a sizable microcontinent , and island arc terranes , beneath what is now the centre of modern Hudson Bay as part of

480-898: A 1994 gathering at the Opaskwayak Cree First Nation reserve. The name "Cree" is derived from the Algonkian -language exonym Kirištino˙ , which the Ojibwa used for tribes around Hudson Bay . The French colonists and explorers, who spelled the term Kilistinon , Kiristinon , Knisteneaux , Cristenaux , and Cristinaux , used the term for numerous tribes which they encountered north of Lake Superior, in Manitoba, and west of there. The French used these terms to refer to various groups of peoples in Canada, some of which are now better distinguished as Severn Anishinaabe (Ojibwa), who speak dialects different from

600-593: A Métis as "a person who self-identifies as Métis, is distinct from other Aboriginal peoples, is of historic Métis Nation Ancestry and who is accepted by the Métis Nation".

Vis-à-vis geographically closer Europe, contrasts stand much more extreme. Arkhangelsk at 64°N in northwestern Russia has an average of 2 °C (36 °F), while the mild continental coastline of Stockholm at 59°N on

840-753: A detailed history of the Hudson Bay basin has been reconstructed. During the majority of the Cambrian Period, this basin did not exist. Rather, this part of the Canadian Shield area was still topographically high and emergent. It was only during the later part of the Cambrian that the rising sea level of the Sauk marine transgression slowly submerged it. During the Ordovician, this part of

Other authorities include it in the Atlantic, in part because of its greater water budget connection with that ocean. The search for a western route to Cathay and the East Indies , which had been actively pursued since the days of Christopher Columbus and John Cabot , in

1200-618: A large increase in electric power exports, since Manitoba load growth will not require this capacity for a generation or more. All of these projects require additional HVDC transmission capacity from the North to the South. One such project, Bipole III, had been discussed with communities on the east side of Lake Winnipeg, but this area has been reserved by the provincial government, making transmission line construction infeasible. The government and Manitoba Hydro have currently rerouted Bipole III through

1320-601: A long time thereafter. In May 1612, Sir Thomas Button sailed from England with two ships to look for Henry Hudson, and to continue the search for the Northwest Passage to Asia. In 1668, Nonsuch reached the bay and traded for beaver pelts, leading to the creation of the Hudson's Bay Company (HBC), which still bears the historic name. The HBC negotiated a trading monopoly from the English Crown for

Its vegetation is typically boreal forest .The northern shores are tundra . Measured by shoreline, Hudson Bay

1800-412: A simplification of identity, and it has become "fashionable" for bands in many parts of Saskatchewan to identify as "Plains Cree" at the expense of a mixed Cree-Salteaux history. There is also a tendency for bands to recategorize themselves as "Plains Cree" instead of Woods Cree or Swampy Cree. Neal McLeod argues this is partly due to the dominant culture's fascination with Plains Indian culture as well as

In the case of disagreement, lodges could leave bands and bands could be formed and dissolved with relative ease. However, as there

8400-400: The bay), and the limited connection with the Atlantic Ocean and its higher salinity. Sea ice is about three times the annual river flow into the bay, and its annual freezing and thawing significantly alters the salinity of the surface layer. Although its exact effects are not fully understood currently, the cyclonic storms in the bay are responsible for synoptic variability of salinity along

8520-445: The closure of an ancient ocean basin . The current general consensus is that it is an arcuate boundary of tectonic origin between the Belcher Fold Belt and undeformed basement of the Superior Craton created during the Trans-Hudson orogeny. This is because no credible evidence for such an impact structure has been found by regional magnetic, Bouguer gravity , or other geologic studies. However, other Earth scientists have proposed that

8640-670: The coast became part of the Mid-Canada Line , watching for a potential Soviet bomber attack over the North Pole. The only Arctic deep-water port in Canada is the Port of Churchill , located at Churchill, Manitoba.

8760-510: The coast were York Factory and Prince of Wales Fort . Communities along the Hudson Bay coast or on islands in the bay are (all populations are as of 2016): The Hudson's Bay Company built forts as fur trade strongholds against the French or other possible invaders. One example is York Factory with angled walls to help defend the fort. In the 1950s, during the Cold War , a few sites along

8880-486: The coast. One consequence of the lower salinity of the bay is that the freezing point of the water is higher than in the rest of the world's oceans, thus decreasing the time that the bay remains ice-free. The increase of river inflows during the winter has decreased the season of sea ice by more than one month since the 1960s. The lower salinity of the bay also has effects on the distribution and prevalence of common marine life such as micro algae. Research has shown that

The major proportion of Cree in Canada live north and west of Lake Superior , in Ontario , Manitoba , Saskatchewan , Alberta , and the Northwest Territories . About 27,000 live in Quebec . In the United States, Cree people historically lived from Lake Superior westward. Today, they live mostly in Montana , where they share

9480-524: The development of extensive reefs that ringed the basin margins that were tectonically uplifted as the basin subsided. During Middle Silurian times, subsidence ceased and this basin was uplifted. It generated an emergent arch, on which reefs grew, that divided the basin into eastern and western sub-basins. During the Devonian Period, this basin filled with terrestrial red beds that interfinger with marine limestone and dolomites. Before deposition

9600-481: The distinction between /s/ and /ʃ/ (š) has been lost, both merging to the former. "Cree is a not a typologically harmonic language. Cree has both prefixes and suffixes, both prepositions and postpositions, and both prenominal and postnominal modifiers (e.g. demonstratives can appear in both positions)." Golla counts Cree dialects as eight of 55 North American languages that have more than 1,000 speakers and which are being actively acquired by children. The Cree are

9720-430: The entire bay is around 0 °C (32 °F) or below. In the extreme northeast, winter temperatures average as low as −29 °C (−20 °F).

The average annual temperature for Churchill at 59°N is −6 °C (21 °F) and Inukjuak, facing cool westerlies in summer at 58°N , an even colder −7 °C (19 °F). By comparison, Magadan , in

9840-525: The evidence of an Archean impact might have been masked by deformation accompanying the later formation of the Trans-Hudson orogen and regard an impact origin as a plausible possibility. The longer periods of ice-free navigation and the reduction of Arctic Ocean ice coverage have led to Russian and Canadian interest in the potential for commercial trade routes across the Arctic and into Hudson Bay. The so-called Arctic Bridge would link Churchill, Manitoba, and

9960-419: The form ililiw , coastal East Cree and Naskapi use iyiyiw (variously spelled iiyiyiu , iiyiyuu , and eeyou ), inland East Cree use iyiniw (variously spelled iinuu and eenou ), and Montagnais use ilnu and innu , depending on dialect. The Cree use "Cree", "cri", "Naskapi, or "montagnais" to refer to their people only when speaking French or English. As hunter-gatherers ,

10080-549: The gravity signal associated with glacial isostatic adjustment from longer–time scale process of mantle convection occurring beneath the Canadian Shield. Based upon this data, geophysicists and other Earth scientists concluded that the Laurentide Ice Sheet was composed of two large domes to the west and east of Hudson Bay. Modelling glacial isostatic adjustment using the GRACE data, they concluded that ≈25 to ≈45% of

The Métis (from the French, Métis – of mixed ancestry) are people of mixed ancestry, such as Cree and French, English, or Scottish heritage. According to Aboriginal Affairs and Northern Development Canada , the Métis were historically the children of French fur traders and Cree women or, from unions of English or Scottish traders and Cree, Northwestern Ojibwe, or northern Dene women ( Anglo-Métis ). The Métis National Council defines

10320-544: The hot land and make the weather milder, with the result that the average temperature surpasses 10 °C (50 °F). The bay receives water from various surrounding rivers and currents originating from the Foxe Basin in the north, resulting in a counterclockwise overall flow. At the extreme southern tip of the extension known as James Bay arises a humid continental climate with a longer and generally hotter summer. (Köppen: Dfb ). The average annual temperature in almost

10440-473: The ice over the winter, and the crew survived onshore at the southern tip of James Bay . In the spring, as the ice receded, Henry Hudson expressed a desire to continue exploring the uncharted region. However, on 22 June 1611, the crew mutinied. They left Hudson and others adrift in a small boat. The fate of Hudson and the other men stranded with him remains undetermined. Nevertheless, there is little evidence in historical documents to suggest that they persisted for

10560-547: The largest group of First Nations in Canada, with 220,000 members and 135 registered bands. Together, their reserve lands are the largest of any First Nations group in the country. The largest Cree band and the second largest First Nations Band in Canada after the Six Nations Iroquois is the Lac La Ronge Band in northern Saskatchewan. Given the traditional Cree acceptance of mixed marriages, it

10680-471: The last 100 years has led to decreases in the extent of the sea ice in Hudson Bay by 19.5% per decade. As well as a lengthening of the ice-free period, which was as short as four months in the late 17th century. The polar climate of Hudson Bay means it is home for a variety of polar climate animals, in the Western Hudson Bay (WHB) beluga whale population is the most significant known group in

10800-430: The latter part of the 15th century, directly resulted in the first sighting of Hudson Bay by Europeans. English explorers and colonists named Hudson Bay after Sir Henry Hudson who explored the bay beginning 2 August 1610, on his ship Discovery . On his fourth voyage to North America, Hudson worked his way around Greenland 's west coast and into the bay, mapping much of its eastern coast. Discovery became trapped in

10920-518: The line was damaged by flooding on 23 May 2017. The Port and the Hudson Bay Railway were sold to Arctic Gateway Group —a consortium of First Nations, local governments, and corporate investors—in 2018.

12000-428: The observed free-air gravity anomaly was due to ongoing glacial isostatic adjustment, and the remainder likely represents longer time-scale effects of mantle convection. Earth scientists have disagreed about what created the semicircular feature known as the Nastapoka arc that forms a section of the shoreline of southeastern Hudson Bay. The Nastapoka arc forms a 155 degree curve and appears to be very circular. Noting

12120-572: The paucity of impact structures on Earth in relation to the Moon and Mars, Carlyle S. Beals proposed that it is possibly part of a Precambrian extraterrestrial impact structure that is comparable in size to the Mare Crisium on the Moon.

The port and the Hudson Bay Railway were then sold to the Arctic Gateway Group —a consortium of First Nations , local governments, and corporate investors—in 2018. On 9 July 2019, ships resupplying Arctic communities began stopping at the port for additional cargo, and the port began shipping grain again on 7 September 2019. The International Hydrographic Organization defines

14040-487: Was diverted by control structures and an artificial channel into the Nelson, thereby increasing flow and saving cost of development. The effects of this diversion on pre-existing water levels and the indigenous Cree and Métis people continue to be felt to this day. Negotiations between the affected Northern communities and Manitoba Hydro continue, to discuss mitigation measures and compensation for loss of traditional resource areas and sites. The water level of Lake Winnipeg

14160-502: Was however 160 km (100 mi) further north than the Nelson River, thus further from the major users of power in southern Manitoba. Jointly harnessing the water increased the flow of the Nelson River by 40%, while the flow of the Burntwood River is now 9 times pre-diversion levels. In 1973 Manitoba Hydro was granted an interim licence to divert 850 m/s (30,000 cu ft/s ) of water from the Churchill River. Construction began
