Niagara River
The Niagara River () is a river that flows north from Lake Erie to Lake Ontario. It forms part of the border between the province of Ontario in Canada (on the west) and the state of New York in the United States (on the east). There are differing theories as to the origin of the river's name. According to Iroquoian scholar Bruce Trigger, ''Niagara'' is derived from the name given to a branch of the locally residing native Neutral Confederacy, who are described as being called the ''Niagagarega'' people on several late-17th-century French maps of the area. According to George R. Stewart, it comes from the name of an Iroquois town called ''Ongniaahra'', meaning "point of land cut in two". The river, which is occasionally described as a strait, is about long and includes Niagara Falls in its course. The falls have moved approximately upstream from the Niagara Escarpment in the last 12,000 years, resulting in a gorge below the falls. Today, the diversion of the river for ele ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

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. Niagara Falls is famed for i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navy Island
Navy Island is a small, uninhabited island in the Niagara River in the province of Ontario, managed by Parks Canada as a National Historic Site of Canada. It is located about upstream from Horseshoe Falls, and has an area of roughly . It is across from the town of Grand Island, New York, US. It was designated a national historic site in 1921 in recognition of its role in shipbuilding and the location of the short-lived Republic of Canada. The site is closed to the public, has no visitor facilities, and has not allowed camping since the expiration of a lease with the Niagara Parks Commission. History Navy Island was settled by the Lamoka people in approximately 2000 BC and Meadowood culture peoples in 1000 BC. During the French colonization of New France, Navy Island was known as ''Île de la Marina''. Here or nearby the French built four ships (bateaux) that they used to service the Great Lakes. Two of these vessels were burnt by the French on Grand Island in 1759. When ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Island, New York
Grand Island is an island town in Erie County, New York, United States. As of the 2020 census, the town's population was 21,389 representing an increase of 5.00% from the 2010 census figure. The town's name derives from the French name ''La Grande Île'', as Grand Island is the largest island in the Niagara River and third largest in New York state. The phrase ''La Grande Île'' appears on the town seal. Grand Island has been home to the Attawandaron Nation and an acquisition of both French and English colonial pursuits. In 1945, Grand Island was part of a plan to make a new World Peace Capital on the international border between Southern Ontario, Canada, and Western New York. The plan proposed placing the United Nations headquarters on adjacent Navy Island (Ontario), which was considered an ideal location because it lay on the boundary between two peaceful countries. An artist's rendering of the World Peace Capital showed the property with bridges spanning both countries (between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Lawrence Seaway
The St. Lawrence Seaway (french: la Voie Maritime du Saint-Laurent) is a system of locks, canals, and channels in Canada and the United States that permits oceangoing vessels to travel from the Atlantic Ocean to the Great Lakes of North America, as far inland as Duluth, Minnesota, at the western end of Lake Superior. The seaway is named for the St. Lawrence River, which flows from Lake Ontario to the Atlantic Ocean. Legally, the seaway extends from Montreal, Quebec, to Lake Erie, and includes the Welland Canal. Ships from the Atlantic Ocean are able to reach ports in all five of the Great Lakes. The St. Lawrence River portion of the seaway is not a continuous canal; rather, it consists of several stretches of navigable channels within the river, a number of locks, and canals along the banks of the St. Lawrence River to bypass several rapids and dams. A number of the locks are managed by the St. Lawrence Seaway Management Corporation in Canada, and others in the United S ...

Welland Canal
The Welland Canal is a ship canal in Ontario, Canada, connecting Lake Ontario and Lake Erie. It forms a key section of the St. Lawrence Seaway and Great Lakes Waterway. Traversing the Niagara Peninsula from Port Weller in St. Catharines to Port Colborne, it enables ships to ascend and descend the Niagara Escarpment and bypass Niagara Falls. It is the fourth canal connecting these waterways; three smaller predecessors also bore the same name. The Welland Canal passes about 3,000 ships which transport about of cargo a year. It was a major factor in the growth of the city of Toronto, Ontario. The original canal and its successors allowed goods from Great Lakes ports such as Cleveland, Detroit, Milwaukee, and Chicago, as well as other heavily industrialized areas of the United States and Ontario, to be shipped to the port of Montreal or to Quebec City, where they were usually reloaded onto ocean-going vessels for international shipping. The Welland Canal in use today is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. There are five lakes, which are Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the Canada–United States border. Hydrologically, lakes Michigan and Huron are a single body joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world's surface fresh water by volume. The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface fresh water). Because of their sea-like characteristics, such as rolling waves, sustained wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Control Dam
The International Control Dam, also known as the International Control Structure, operated by Ontario Power Generation, is a weir that controls the water diversions from the Niagara River and dispatches the water between the New York Power Authority and Ontario Power Generation in accordance with the terms of the 1950 Niagara Treaty. It was completed in 1954. To preserve Niagara Falls' natural beauty and to ensure an "unbroken curtain of water" is flowing over the falls, the 1950 treaty was signed by the U.S. and Canada to limit water usage by power plants. The treaty allows higher summertime diversion at night when tourists are fewer and during the winter months when there are even fewer tourists. The treaty states that during daylight time during the tourist season (April 1 to October 31) there must be 100,000 cubic feet per second (2,800 m3/s) of water flowing over the falls, and during the night and off-tourist season there must be 50,000 cubic feet per second (1,400 m3/s) of ...

Gigawatt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Robert Moses Niagara Power Plant
The Robert Moses Niagara Hydroelectric Power Station is a hydroelectric power station in Lewiston, New York, near Niagara Falls. Owned and operated by the New York Power Authority (NYPA), the plant diverts water from the Niagara River above Niagara Falls and returns the water into the lower portion of the river near Lake Ontario. It uses 13 generators at an installed capacity of . Named for New York City planner Robert Moses, the plant was built to replace power production after the Schoellkopf Power Station, a nearby hydroelectric plant, collapsed in 1956. It stands across the river from Sir Adam Beck Hydroelectric Power Stations in Niagara Falls, Ontario, Canada. History Origins The land that the Robert Moses Niagara Power Plant occupies has a long history of use. In 1805, Augustus and Peter Porter of Buffalo, New York, purchased the American Falls from New York in a public auction (and later acquired the rights to the eastern rapids above the falls) with a stated plan to g ...

Sir Adam Beck Hydroelectric Power Stations
Sir Adam Beck Hydroelectric Generating Stations are two hydroelectric generating stations in Niagara Falls, Ontario, Canada. Sir Adam Beck Generating Station I, Sir Adam Beck Generating Station II and the Sir Adam Beck Pump Generating Station are all owned by Ontario Power Generation. Following the development of several smaller generating stations around Niagara Falls in the late 19th and early 20th centuries, the Province of Ontario authorized the construction of the first major publicly owned generating station in the province. At the time it was built, it was the largest hydroelectric generating station in the world. The stations divert water from the Niagara and Welland rivers above Niagara Falls which is then released into the lower portion of the Niagara River, and together produce up to . Adam Beck I Adam Beck I contains 10 generators and first produced power in 1922. It was originally called the Queenston-Chippawa Hydroelectric Plant and was renamed after Adam Beck in 1 ...

Niagara Whirlpool
The Niagara Whirlpool is a natural whirlpool within the Niagara River located along the Canada–U.S. border between New York and Ontario. The whirlpool is in the Niagara Gorge, downstream from Niagara Falls. The whirlpool's greatest depth is . Formation It is estimated that the whirlpool formed approximately 4,200 years ago by the upstream erosion of the Niagara Escarpment by the Niagara River. Niagara Falls is located along the boundary of the Niagara Escarpment and has been retreating upstream since its formation. During this normally slow process, the retreating falls intersected with an ancient pre-glacial river bed inside Saint David's Buried Gorge. During the retreat of ice from the Wisconsin glaciation of the Last Glacial Period, the gorge was filled with loose sediment and rock. When the falls intersected with this buried gorge, the river quickly washed away the filled-in silt and rocks. The ancient buried gorge was nearly perpendicular to the Niagara River. ...
