Niagara River
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 river, occasionally described as a strait, is approximately 58 kilometres (36 miles) long and is known for 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 downstream from the falls, includes the Niagara Whirlpool and additional rapids.
