The Niagara River is a natural waterway located in North America, flowing from Lake Erie to Lake Ontario. It serves as a border between the United States and Canada, stretching approximately 36 miles (58 kilometers). The river is known for its stunning scenery and significant role in the Niagara Falls region. The river is characterized by its fast currents and steep drops, particularly at the falls, where it plunges over 167 feet (51 meters). It is also an important source of hydroelectric power, with several power plants harnessing its energy. The Niagara River supports diverse ecosystems and recreational activities, including boating and fishing.
