Niagara Falls Facts

  • The water that flows over Niagara Falls comes from four of the five Great Lakes: Erie, Huron, Michigan and Superior. From the Falls, the water travels down the Niagara River to Lake Ontario, then to the St. Lawrence River and finally to the Atlantic Ocean.
  • Originally, 5.5 billion gallons per hour of water flowed over Niagara Falls. Now, however, half of this water is diverted for power by the United States and Canada.
  • The average depth of the water below Niagara Falls is 170 feet, which is as deep as the Niagara Gorge banks are high.
  • Niagara Falls is the collective name for three waterfalls — the Horseshoe Falls, the Bridal Veil Falls and the American Falls — that overlap the international borders of Canada and the United States.
  • Fish actually travel over the Falls and about 90% of them survive. Experts believe that the white foam from the rushing waters cushions their fall.
  • Back in the 1800s, Niagara Falls was nearly frozen solid and only a small trickle of water traveled over the cliffs.
  • About 600,000 gallons of water travel down Niagara Falls every second.
  • About 20% of the drinking water in the United States goes over Niagara Falls.
  • The formation of Niagara Falls is the result of glaciers.
  • Parts of the movies “Superman” and “Niagara,” starring Marilyn Monroe, were filmed at Niagara Falls.
