Niagara Falls in the context of "Great Lakes Waterway"

The Erie Canal is a historic canal in upstate New York that runs east–west between the Hudson River and Lake Erie. Completed in 1825, the canal was the first navigable waterway connecting the Atlantic Ocean to the upper Great Lakes above Niagara Falls, vastly reducing the costs of transporting people and goods across the Appalachians. The Erie Canal accelerated the settlement of the Great Lakes region, the westward expansion of the United States, and the economic ascendancy of New York state.

A canal from the Hudson River to the Great Lakes was first proposed in the 1780s, but a formal survey was not conducted until 1808. The New York State Legislature authorized construction in 1817. Political opponents of the canal (referencing its lead supporter New York Governor DeWitt Clinton) denigrated the project as "Clinton's Folly" and "Clinton's Big Ditch". Nonetheless, the canal saw quick success upon opening on October 26, 1825, with toll revenue covering the state's construction debt within the first year of operation. The westward connection gave New York City a strong advantage over all other US ports and brought major growth to canal cities such as Albany, Utica, Syracuse, Rochester, and Buffalo.

The geography of New York varies widely across the state. Most of New York is dominated by farms, forests, rivers, mountains, and lakes. New York's Adirondack Park is larger than any U.S. National Park in the contiguous United States. Niagara Falls, on the Niagara River as it flows from Lake Erie to Lake Ontario, is a popular attraction. The Hudson River begins near Lake Tear of the Clouds and flows south through the eastern part of the state without draining lakes George or Champlain. Lake George empties at its north end into Lake Champlain, whose northern end extends into Canada, where it drains into the Richelieu River and then the St. Lawrence. Four of New York City's five boroughs are on the three islands at the mouth of the Hudson River: Manhattan Island, Staten Island, and Brooklyn and Queens on Long Island.

"Upstate" is a common term for New York counties north of suburban Westchester, Rockland and Dutchess counties. Upstate New York typically includes the Catskill Mountains or areas North of the Catskill Mountains, the Capital District, The Adirondacks, the Erie Canal, Lake Champlain, Otsego Lake, Oneida Lake; rivers such as the Delaware, Genesee, Mohawk, and Susquehanna. The highest elevation in New York is Mount Marcy of the Adirondack Mountains. New York is the 27th-largest state.

A whirlpool is a body of rotating water produced by opposing currents or a current running into an obstacle. Small whirlpools form when a bath or a sink is draining. More powerful ones formed in seas or oceans may be called maelstroms (/ˈmeɪlstrɒm, -rəm/ MAYL-strom, -⁠strəm). Vortex is the proper term for a whirlpool that has a downdraft.

In narrow ocean straits with fast flowing water, whirlpools are often caused by tides. Many stories tell of ships being sucked into a maelstrom, although only smaller craft are actually in danger. Smaller whirlpools appear at river rapids and can be observed downstream of artificial structures such as weirs and dams. Large cataracts, such as Niagara Falls, produce strong whirlpools.

The Niagara Escarpment is an approximately 1,050-kilometre-long (650-mile) discontinuous, arc-shaped but generally northward-facing escarpment, or cuesta, in Canada and the United States. The escarpment begins south of Lake Ontario and circumscribes the top of the Great Lakes Basin running from New York through Ontario, Michigan, and Wisconsin. The escarpment is the cliff over which the Niagara River plunges at Niagara Falls, for which it is named.

The escarpment is a UNESCO World Biosphere Reserve. The reserve has the oldest forest ecosystem and trees in eastern North America.

The Niagara River (/naɪˈæɡərə, -ɡrə/ ny-AGG-ər-ə, -⁠grə) flows north from Lake Erie to Lake Ontario, forming part of the border between Ontario, Canada, to the west, and New York, United States, to the east. The origin of the river's name is debated. Iroquoian scholar Bruce Trigger suggests it is derived from a branch of the local Neutral Confederacy, referred to as the Niagagarega people on several late-17th-century French maps. George R. Stewart posits that it comes from an Iroquois town named Ongniaahra, meaning "point of land cut in two."

The river, occasionally described as a strait, is approximately 58 kilometres (36 mi) long and includes the Niagara Falls. Over the past 12,000 years, the falls have moved roughly 11 kilometres (6.8 mi) upstream from the leading edge of the Niagara Escarpment, creating a gorge below the falls. Today, the diversion of the river for electricity generation has significantly slowed the rate of erosion. The total elevation drop along the river is 99 metres (325 ft). The Niagara Gorge, downstream from the falls, includes the Niagara Whirlpool and additional rapids.

The Welland Canal is a ship canal in Ontario, Canada, and part of the St. Lawrence Seaway and Great Lakes Waterway. The canal traverses the Niagara Peninsula between Port Weller on Lake Ontario and Port Colborne on Lake Erie, and was built because the Niagara River—the only natural waterway connecting the lakes—was unnavigable due to Niagara Falls. The Welland Canal enables ships to ascend and descend the Niagara Escarpment, and has followed four different routes since it opened.

The Welland Canal passes about 3,000 ships which transport about 40 million tonnes (88 billion pounds) 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.

Leonardo Torres Quevedo (Spanish: [leoˈnaɾðo ˈtores keˈβeðo]; 28 December 1852 – 18 December 1936) was a Spanish civil engineer, mathematician and inventor, known for his numerous engineering innovations, including aerial trams, airships, catamarans, and remote control. He was also a pioneer in the field of computing and robotics. Torres was a member of several scientific and cultural institutions and held such important positions as the seat N of the Real Academia Española (1920–1936) and the presidency of the Spanish Royal Academy of Sciences (1928–1934). In 1927 he became a foreign associate of the French Academy of Sciences.

His first groundbreaking invention was a cable car system patented in 1887 for the safe transportation of people, an activity that culminated in 1916 when the Whirlpool Aero Car was opened in Niagara Falls. In the 1890s, Torres focused his efforts on analog computation. He published Sur les machines algébriques (1895) and Machines à calculer (1901), technical studies that gave him recognition in France for his construction of machines to solve real and complex roots of polynomials. He made significant aeronautical contributions at the beginning of the 20th century, becoming the inventor of the non-rigid Astra-Torres airships, a trilobed structure that helped the British and French armies counter Germany's submarine warfare during World War I. These tasks in dirigible engineering led him to be a key figure in the development of radio control systems in 1901–05 with the Telekine, which he laid down modern wireless remote-control operation principles.

Niagara Falls is a city in Niagara County, New York, United States. As of the 2020 census, the city had a total population of 48,671. It is adjacent to the Niagara River, across from the city of Niagara Falls, Ontario, and named after the famed Niagara Falls which they share. The city is within the Buffalo–Niagara Falls metropolitan area and the Western New York region.

While the city was formerly inhabited by Native Americans, Europeans who migrated to the Niagara Falls in the mid-17th century began to open businesses and develop infrastructure. Later in the 18th and 19th centuries, scientists and businessmen began harnessing the power of the Niagara River for electricity and the city began to attract manufacturers and other businesses drawn by the promise of inexpensive hydroelectric power. After the 1960s, however, the city and region experienced an economic decline. As industries left the region, affluent and middle-class families relocated from Niagara Falls to other metropolitan areas around the country.
