Portage Diversion
The Portage Diversion () (also known as the Assiniboine River Floodway) is a water control structure on the Assiniboine River near Portage la Prairie, Manitoba, Canada. The project was made as part of a larger attempt to prevent flooding in the Red River Valley. The Portage Diversion consists of two separate gates which divert some of the flow of water in the Assiniboine River to a 29 km long diversion channel that empties into Lake Manitoba near Delta Beach. This helps prevent flooding on the Assiniboine down river from the diversion, including in Winnipeg, where the Assiniboine River meets the Red River. During flood years such as the 2011 Assiniboine River flood, inlet flows to the Portage Diversion control structure were measured at over . This amount of water would have disastrous effects if left to flood southern Manitoba. During the flood of spring 2011, the Portage Diversion handled roughly half the flow of Niagara Falls. The Assiniboine River and diking system can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red River Of The North
The Red River (french: rivière Rouge or ) is a river in the north-central United States and central Canada. Originating at the confluence of the Bois de Sioux and Otter Tail rivers between the U.S. states of Minnesota and North Dakota, it flows northward through the Red River Valley, forming most of the border of Minnesota and North Dakota and continuing into Manitoba. It empties into Lake Winnipeg, whose waters join the Nelson River and ultimately flow into Hudson Bay. The Red River is about long, of which about are in the United States and about are in Canada.Red River Map 3 Minnesota DNR; map shows the international border at 155.

Flood Control Projects
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated ... and Wetland conservation, removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise.

Buildings And Structures In Manitoba
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shellmouth Reservoir
The Shellmouth Reservoir (also known as Lake of the Prairies) is a man-made reservoir on the Assiniboine River in Manitoba and Saskatchewan, Canada. The Shellmouth Dam () is a multi-purpose, embankment dam built by the Prairie Farm Rehabilitation Administration (PFRA). The dam and reservoir are part of a strategy to reduce the risk of flood damage for Winnipeg and other communities along the Assiniboine River. For example, in the 1997 Red River flood, the inflow to the reservoir peaked at while the outflow never exceeded . The reservoir is also used to supplement flows on the Assiniboine when conditions are dry, ensuring water supply for Brandon, Portage la Prairie, irrigators, and some industries. For example in early August, 2021 the flow in Brandon was a little over 9 cms while the outflow from Shellmouth was 5.7 cms and inflow was less than 0.5 cms. Therefore without the dam the flow in the Assiniboine at Brandon would be a bit under 4 cms. Asessippi Provincial Park is establ ...

Red River Floodway
The Red River Floodway (french: Canal de dérivation de la rivière Rouge) is an artificial flood control waterway in Western Canada. It is a long channel which, during flood periods, takes part of the Red River's flow around the city of Winnipeg, Manitoba to the east and discharges it back into the Red River below the dam at Lockport. It can carry floodwater at a rate of up to , expanded in the 2000s from its original channel capacity of . The Floodway was pejoratively nicknamed "Duff's Ditch" by opponents of its construction, after Premier Duff Roblin, whose Progressive Conservative government initiated the project, partly in response to the disastrous 1950 Red River flood. It was completed in time and under budget. Subsequent events have vindicated the plan. Since its completion in 1968, the Floodway is estimated to have prevented over $40 billion (CAD) in cumulative flood damage. It was designated a National Historic Site of Canada in 2000, as the floodway is an outst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niagara Falls
Niagara Falls () is a group of three waterfalls at the southern end of Niagara Gorge, spanning the border between the province of Ontario in Canada and the state of New York in the United States. The largest of the three is Horseshoe Falls, which straddles the international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls lie within the United States. Bridal Veil Falls is separated from Horseshoe Falls by Goat Island and from American Falls by Luna Island, with both islands situated in New York. Formed by the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls have the highest flow rate of any waterfall in North America that has a vertical drop of more than . During peak daytime tourist hours, more than of water goes over the crest of the falls every minute. Horseshoe Falls is the most powerful waterfall in North America, as measured by flow rate.

2011 Assiniboine River Flood
The 2011 Assiniboine River flood was caused by above average precipitation in Western Manitoba and Saskatchewan. This was a 1 in 300 year flood that affected much of Western Manitoba. The flooding in Manitoba was expected to mostly involve the 2011 Red River Flood but instead the more severe flooding was found on the Assiniboine in the west. Early signs The 2011 flood really started in the fall of 2010 with several major rainfall events and generally wet conditions. Initially, it was predicted that the flood along the Assiniboine River would be similar to the flood of 1995. During the winter of 2010–2011 the Shellmouth Reservoir was emptied in preparation, to store water for the coming spring flood. With more and more precipitation, the estimates on the flood were revised upwards. The first major settlement to experience the floodwater was St. Lazare, Manitoba which was located near the confluence of the Assiniboine River and Qu'Appelle River. Dikes were built up to protect ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winnipeg
Winnipeg () is the capital and largest city of the province of Manitoba in Canada. It is centred on the confluence of the Red and Assiniboine rivers, near the longitudinal centre of North America. , Winnipeg had a city population of 749,607 and a metropolitan population of 834,678, making it the sixth-largest city, and eighth-largest metropolitan area in Canada. The city is named after the nearby Lake Winnipeg; the name comes from the Western Cree words for "muddy water" - “winipīhk”. The region was a trading centre for Indigenous peoples long before the arrival of Europeans; it is the traditional territory of the Anishinabe (Ojibway), Ininew (Cree), Oji-Cree, Dene, and Dakota, and is the birthplace of the Métis Nation. French traders built the first fort on the site in 1738. A settlement was later founded by the Selkirk settlers of the Red River Colony in 1812, the nucleus of which was incorporated as the City of Winnipeg in 1873. Being far inland, the local cl ...

Portage Diversion Maximum Capacity
Portage or portaging (Canada: ; ) is the practice of carrying water craft or cargo over land, either around an obstacle in a river, or between two bodies of water. A path where items are regularly carried between bodies of water is also called a ''portage.'' The term comes from French, where means "to carry," as in "portable". In Canada, the term "carrying-place" was sometimes used. Early French explorers in New France and French Louisiana encountered many rapids and cascades. The Native Americans carried their canoes over land to avoid river obstacles. Over time, important portages were sometimes provided with canals with locks, and even portage railways. Primitive portaging generally involves carrying the vessel and its contents across the portage in multiple trips. Small canoes can be portaged by carrying them inverted over one's shoulders and the center strut may be designed in the style of a yoke to facilitate this. Historically, voyageurs often employed tump lines on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Manitoba
Lake Manitoba (french: Lac Manitoba) is the List of lakes of Canada, 14th largest lake in Canada and the List of lakes by area, 33rd largest lake in the world with a total area of . It is located within the Provinces and territories of Canada, Canadian province of Manitoba about northwest of the province's capital, Winnipeg, at . History The lake, its shores populated by the Assiniboine and Cree, was made known to Europeans by Pierre Gaultier de Varennes, sieur de La Vérendrye, La Vérendrye in the mid-1730s. He and his sons travelled from Fort La Reine through this lake to explore the Saskatchewan River and its environs. Forts were established on both the Saskatchewan and Cedar Lake (Manitoba), Cedar Lake. It also was part of the fur trade route to Hudson Bay. The name derives from Cree language, Cree ''manitou-wapow'' or Ojibwe language, Ojibwa ''manidoobaa'', both meaning "straits of Manitou, the Great Spirit", a toponym referring to what are now called The Narrows in the cent ...

Red River Valley
The Red River Valley is a region in central North America that is drained by the Red River of the North; it is part of both Canada and the United States. Forming the border between Minnesota and North Dakota when these territories were admitted as states in the United States, this fertile valley has been important to the economies of these states and to Manitoba, Canada. The population centers of Moorhead, Minnesota, Fargo and Grand Forks, North Dakota, and Winnipeg, Manitoba developed in the valley as settlement by ethnic Europeans increased in the late nineteenth century. Completion of major railroads, availability of cheap lands, and forceful removal of Indigenous people as well as a subsequent refusal to recognize Indigenous land claims attracted many new settlers. Some developed large-scale agricultural operations known as bonanza farms, which concentrated on wheat commodity crops. Paleogeographic Lake Agassiz laid down the Red River Valley Silts. The valley was long an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
