Lake Agassiz was a large proglacial lake that existed in central North America during the late Pleistocene, fed by meltwater from the retreating Laurentide Ice Sheet at the end of the last glacial period. At its peak, the lake's area was larger than all of the modern Great Lakes combined.
Lake Winnipeg is a very large, relatively shallow 24,514-square-kilometre (9,465 sq mi) lake in North America, in the province of Manitoba, Canada. Its southern end is about 55 kilometres (34 mi) north of the city of Winnipeg. Lake Winnipeg is Canada's sixth-largest freshwater lake and the third-largest freshwater lake contained entirely within Canada, but it is relatively shallow excluding a narrow 36 m (118 ft) deep channel between the northern and southern basins. It is the eleventh-largest freshwater lake on Earth. The lake's east side has pristine boreal forests and rivers that were in 2018 inscribed as Pimachiowin Aki, a UNESCO World Heritage Site. The lake is 416 km (258 mi) from north to south, with remote sandy beaches, large limestone cliffs, and many bat caves in some areas. Manitoba Hydro uses the lake as one of the largest reservoirs in the world. There are many islands, most of them undeveloped.
Lake Manitoba is the 14th largest lake in Canada and the 33rd largest lake in the world with a total area of 4,624 square kilometres (1,785 sq mi). It is located within the Canadian province of Manitoba about 75 kilometres (47 mi) northwest of the province's capital, Winnipeg, at 50°59′N98°48′W.
Lake Winnipegosis is a large (5,370 km2) lake in central North America, in Manitoba, Canada, some 300 km northwest of Winnipeg. It is Canada's eleventh-largest lake.
The Saskatchewan River is a major river in Canada. It stretches about 550 kilometres (340 mi) from where it is formed by the joining of the North Saskatchewan River and South Saskatchewan River just east of Prince Albert, Saskatchewan, to Lake Winnipeg. It flows roughly eastward across Saskatchewan and Manitoba to empty into Lake Winnipeg. Through its tributaries the North Saskatchewan and South Saskatchewan, its watershed encompasses much of the prairie regions of Canada, stretching westward to the Rocky Mountains in Alberta and north-western Montana in the United States.
The Assiniboine River is a 1,070-kilometre (660 mi) river that runs through the prairies of Western Canada in Saskatchewan and Manitoba. It is a tributary of the Red River. The Assiniboine is a typical meandering river with a single main channel embanked within a flat, shallow valley in some places and a steep valley in others. Its main tributaries are the Qu'Appelle, Souris, and Whitesand Rivers. For early history and exploration see Assiniboine River fur trade.
The Souris River or Mouse River is a river in central North America. Approximately 435 miles (700 km) in length, it drains about 23,600 square miles (61,100 km2) in Canada and the United States.
The Churchill River is a major river in Alberta, Saskatchewan and Manitoba, Canada. From the head of the Churchill Lake it is 1,609 kilometres (1,000 mi) long. It was named after John Churchill, 1st Duke of Marlborough and governor of the Hudson's Bay Company from 1685 to 1691. The Cree name for the river is Missinipi, meaning "big waters". The Denesuline name for the river is des nëdhë́, meaning "Great River".
Treaty Five is a treaty between Queen Victoria and Saulteaux and Swampy Cree non-treaty band governments and peoples around Lake Winnipeg in the District of Keewatin. Much of what is today central and northern Manitoba was covered by the treaty, as were a few small adjoining portions of the present-day provinces of Saskatchewan and Ontario.
Provincial Trunk Highway 6 is a provincial primary highway located in the Canadian province of Manitoba. It runs from the Perimeter Highway of Winnipeg to the Thompson south city limits. It is also the main highway connecting Winnipeg to northern Manitoba. The speed limit is 100 km/h. The route is also used to deliver nickel from the Thompson mine to the Royal Canadian Mint in Winnipeg. The section of highway between its southern terminus near Winnipeg and the second junction with PTH 68 near Eriksdale is part of the Northern Woods and Water Route. The portion of the highway between Ponton and Thompson was known as Highway 391 prior to 1986.
Easterville is an unincorporated community, designated as a northern community, in the Canadian province of Manitoba.
Grand Rapids is a town in Manitoba, Canada, on the northwestern shore of Lake Winnipeg where the Saskatchewan River enters the lake. As the name implies, the river had a significant drop at this point. In modern days, a large hydroelectric plant has been built there. Cedar Lake, a short distance upriver, provides a natural water source for the plant. Provincial Trunk Highway 6, the region's primary roadway, crosses the Saskatchewan River at the Grand Rapids Bridge.
Misipawistik Cree Nation is a Cree community in northern Manitoba. Misipawistik in the local Cree language means 'Rushing Rapids', which was once a historical Canadian landmark before the construction of the Manitoba Hydro-electric Dam in the late 1950s.
Highway 35 is a paved undivided provincial highway in the Canadian province of Saskatchewan.. It runs from the US Border near Port of Oungre to a dead end near the north shore of Tobin Lake. Saskatchewan Highway 35 (SK Hwy 35) is about 569 kilometres (354 mi) long. The CanAm Highway comprises Saskatchewan Highways 35, SK Hwy 39, SK Hwy 6, SK Hwy 3, SK Hwy 2 and U.S. Route 85. 74.6 kilometres (46.4 mi) of SK Hwy 35 contribute to the CanAm Highway between Port of Oungre on the Canada – United States border and Weyburn. Mudslides, and spring flooding were huge road building and maintenance problems around Nipawin as well as along the southern portion of the route named the Greater Yellow Grass Marsh. Over 20 early dams were built until the problem was addressed with the Rafferty-Alameda Project on the Souris River and the construction of the Qu'Appelle River Dam which have helped to eliminate washed out roads and flooded communities. The highway through the homesteading community followed the Dominion Land Survey on the square until reaching the Saskatchewan River at Nipawin. The completion of the combined railway and traffic bridge over the Saskatchewan River at Nipawin in the late 1920s retired the ferry and basket crossing for traffic north of Nipawin. The E.B. Campbell Dam built in 1963 northeast of Nipawin created Tobin Lake, and Codette Lake was formed with the construction of the Francois-Finlay Hydroelectric dam at Nipawin. The railway/traffic bridge that formed part of Highway 35 was the only crossing utilized at Nipawin until a new traffic bridge was constructed in 1974. The new bridge then became part of the combined Highway 35 and 55 until the highway parts just east of White Fox. Highway 35 then continued north along the west side of Tobin Lake. The railway/traffic bridge continues to be utilized for one lane vehicle traffic controlled by traffic lights, and continues as the "old highway 35" on the west side of the river until it joins with the current Highway 35/55.
Hydroelectric development in Easterville, Chemawawin began in 1962. By the early 1960s a new era began to emerge in Northern Manitoba with the development of hydroelectric projects. In 1962 the government of Manitoba contacted the Chemawawin Cree Nation asking them to surrender their lands so that the Grand Rapids Dam could be constructed. Subsequent flooding of the land that belonged to the Chemawawin people meant relocating them to Easterville, Manitoba. The Grand Rapids Forebay Administration Committee, or Forebay Committee for short, sent what is known as the "Letter of intent" or "Forebay Agreement" to the Chemawawin community stipulating a number of promises to them should they decide to relocate. Ultimately the Chemawawin people relocated to Easterville and continue to live there today. The agreements made between the government of Manitoba and the Chemawawin Indian Band are highly disputed in terms of whether the agreements were fulfilled.
The Saskatchewan River Delta (SRD), also known as Cumberland Marshes, is a large alluvial delta that straddles the border of the provinces of Saskatchewan and Manitoba in Western Canada. Currently terminating at Cedar Lake, Manitoba, the delta is composed mainly of various types of wetlands, shallow lakes, and active and abandoned river channels bordered by forested natural levees. Sixty-five percent of the delta is occupied by vegetated wetlands, over one third of which comprise peat-forming fens and bogs. Geographically, the SRD consists of two parts – western and eastern – separated by a prominent moraine that was deposited by the Laurentide Ice Sheet during late stages of the Wisconsinan glacial epoch. These two components, commonly termed the "upper delta" and "lower delta", together occupy an area of approximately 10,000 km2 (3,900 sq mi) making the SRD one of the largest active inland deltas in North America. The broad wetland tracts of the upper delta in Saskatchewan are sometimes referred to as the Cumberland Marshes. Approximately 5% of the delta surface has been drained for agricultural use following feasibility studies by the Prairie Farm Rehabilitation Administration in the 1950s.
Cumberland House Provincial Park is a located on Cumberland Island at Cumberland House in the Canadian province of Saskatchewan. The site is the location of the first inland Hudson's Bay Company post in Saskatchewan and the oldest village in the province. A powder magazine shed built in 1886 and artifacts from the HBC Northcote steamship are the remaining historic elements on the site.
Moose Lake is a lake located near the Saskatchewan River Delta in Manitoba, Canada. It is separated into two irregularly shaped lobes, North Moose Lake and South Moose Lake, by the Moose Lake Narrows Control Structure, which was built in 1964. South Moose Lake drains south into Cedar Lake via Moose Creek; these two lakes form the reservoir of the Grand Rapids Generating Station, and the sluice gates at Moose Lake Narrows helps regulate their water levels. The lake as a whole lies at an elevation of 255 metres (837 ft) and covers 1,367 square kilometres (528 sq mi). The community of Moose Lake is on the south shore of the lake.
Pipestone Creek is a river in the Souris River watershed. Its flow begins in southeastern Saskatchewan, just south of the town of Grenfell and travels in a southeastern direction into Manitoba in the Westman Region where it empties into Oak Lake through the Oak Lake Marsh.
