110 000 m3 (average); see also http://en.wikipedia.org/wiki/Niagara_Falls.
So much that is is hard to imagine. Niagara Falls flows at a rate of about nine million gallons per minute.
68, billion gallons (257408001040 Liters)
Niagara Falls flows between Niagara Falls and Niagara Falls. The water at Niagara Falls drops -- from the crest of the falls to the bottom of the falls. The Niagara River flows from Lake Erie to the crest of the falls, over the falls, and thence to Lake Ontario. The Niagara River forms part of the international boundary between Canada and the US. There are two cities at Niagara Falls, and both are named Niagara Falls. The one in Canada is Niagara Falls, Ontario, and the one in the US is Niagara Falls, New York.
Niagara Falls --- IS --- a cliff.... that's what makes a waterfall. A waterfall is a place where water flows over the edge of a cliff.
Lake Erie feeds Niagara Falls. The water going over the Falls flows in Lake Ontario (which is, of course, downstream from the Falls).
Niagara Falls is a waterfall on the Niagara River in North America. The Niagara River flows along the Canada-United States international boundary from Lake Erie into Lake Ontario. The cities of Niagara Falls, Ontario, and Niagara Falls, New York, are on opposite sides of the river at the waterfall. The co-ordinates are 43.080°N 79.071°W
the Canadian side
Niagara Falls retreats as water flows it picks up loose rock, sand and dirt; eroding the surface back upstream.
The Niagara River flows from Lake Erie into Lake Ontario.
There are actually three falls at Niagara. The most spectacular is the Horseshoe Falls, which is almost entirely in Canada. By far, the greatest amount of water flows over the Horseshoe Falls. A much smaller amount flows over the American Falls, and a relatively little amount flows over the Bridal Veil Falls.
Niagara Falls is actually on the Niagara River. The water leaves Lake Erie at the the city of Buffalo, New York and approximately 30 miles downstream falls over Niagara Falls. The Niagara River empties into Lake Ontario, eventually into the St. Lawrence River and finally into the Atlantic Ocean.
Horseshoe Falls is a part of the Niagara Falls. There are three parts , Bridal Veil, Horse Shoe and The American Falls. Niagara Falls is on the Niagara River, and that river flows from Lake Erie, to Lake Ontario. At that point the Niagara River is the International boundary, between Canada and the United States of America. Jim B. Toronto.
About 3.24 billion (3.24*1010) gallons of water per day flows over Niagara Falls.
it flows between America and Canada hope this helps
