Links Lake Erie to Lake Ontario, flowing roughly 58 km (36 miles) north.
Home to the world-renowned Horseshoe Falls (Canadian side), American Falls, and Bridal Veil Falls (US side).
Forms a natural boundary between the state of New York (USA) and the province of Ontario (Canada).
Its dramatic drop in elevation provides immense potential for hydroelectric power generation, powering millions.

Frequently Asked Questions (FAQs)
What two Great Lakes does the Niagara River connect?
The Niagara River connects Lake Erie to Lake Ontario. Water flows from the higher elevation of Lake Erie down to the lower elevation of Lake Ontario, creating the dramatic drop at Niagara Falls.
Which countries share the Niagara River as a border?
The Niagara River forms a significant portion of the international border between the United States (specifically New York state) and Canada (specifically Ontario province).
How many main waterfalls make up Niagara Falls, and what are their names?
Niagara Falls is composed of three main waterfalls: Horseshoe Falls (also known as Canadian Falls), the American Falls, and the smaller Bridal Veil Falls.
How were the Niagara Falls formed?
The Niagara Falls were primarily formed by the erosive power of meltwater from the retreating Wisconsin Ice Sheet approximately 12,500 years ago. The water cut through softer shale layers beneath harder dolomite, creating the escarpment and falls.
What is the primary economic importance of the Niagara River beyond tourism?
Beyond its immense tourism appeal, the Niagara River is crucial for hydroelectric power generation. Its significant drop in elevation provides a powerful flow of water that is harnessed by large power plants on both the American and Canadian sides, providing electricity to millions.
