Niagara Falls is located in Niagara County
just north of Buffalo
between Lake Ontario and Lake Erie in the Western Region
of the state. It also is between Lewiston and Tonawanda along Interstate 190, on the banks of the Niagara River near the Canadian border. Young in geologic time, the falls were created by the recession and melting of a mammoth ice sheet. They originally formed seven miles north in what is now Lewiston. Due to erosion, the falls are currently about midway between lakes Erie and Ontario, Canada on the Niagara River.
In 1895, the world's first commercial hydroelectric plant was built at the falls. The Niagara Power Project opened in 1961 with 13 generators and a total installed power of 2,190,000 kilowatts.
Niagara Falls is accessible from the south via Interstates 90, 290 and 190.
Niagara Falls is part of the Buffalo-Niagara Falls, New York metro area.
