Definitions for niagara river
Niagara, Niagara River(noun)
a river flowing from Lake Erie into Lake Ontario; forms boundary between Ontario and New York
A river in North America flowing to the north from Lake Erie to Lake Ontario and including the Niagara Falls.
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 and New York State in the United States. There are differing theories as to the origin of the name of the river. 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 56 kilometres long and includes Niagara Falls in its course. The falls have moved approximately 11 kilometres 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 electrical generation has significantly reduced the rate of erosion. Power plants on the river include the Sir Adam Beck Hydroelectric Power Stations on the Canadian side, and the Robert Moses Niagara Power Plant on the American side. Together, they generate 4.4 gigawatts of electricity. The International Control Works, built in 1954, regulates the river flow. Ships on the Great Lakes use the Welland Canal, part of the Saint Lawrence Seaway, on the Canadian side of the river, to bypass Niagara Falls.
