• The Canadian "Horseshoe" Niagara Falls are 180 feet high (60 meters) and 2,500 feet (833 meters) wide. The depth of the Niagara River below the "Horseshoe" Niagara Falls is 180 feet {60 meters} and as deep as Niagara Gorge walls are high. The huge volume of water that rapidly flows over the "Horseshoe" Falls causes the rushing waters of the Niagara River to appear green in color.

• The water over the Niagara Falls comes from four of the five, (fresh water) Great Lakes. From Niagara Falls, water flows down the Niagara River merging with the waters of Lake Ontario, then into the mighty, St. Lawrence River located in northeast Canada. These fresh waters eventually flow north into the Atlantic Ocean.

• Originally, over 5,000,000,000 gallons (about 2 trillion liters) of water PER HOUR flowed over the edge of Niagara Falls. Put another way, 35,000,000 gallons of fresh water PER MINUTE roared over the edge of this natural wonder of the world. Half of this great water volume is now, diverted {at night and during the off season} for hydro-electric power generation by the governments of Canada and the United States. Niagara Falls is the largest producer of hydro-electric power in the world, at this time.

• The Canada "Horseshoe" Falls began flowing over 12,000 years ago, following the end of the last ice age and resulting glacial retreat. The Canada "Horseshoe" Niagara Falls was originally located seven miles (eleven km.) downstream from its current location. Over the thousands of years, the Niagara Falls created the Niagara Gorge by water erosion, moving upstream at over 4 feet per year (1.33 meters) and located today, at the city of Niagara Falls. Measurements have been taken since the 1790s and records have been kept since that time of the movement of the Niagara Falls.
