How much water goes over Niagara Falls?

One of the most staggering statistics about Niagara Falls is how much water cascades over the river below. Niagara Falls – which encompasses the American Falls, Bridal Veil Falls and Horseshoe Falls – is recognized as having the greatest flow rate of any waterfall in the world. Together, more than 168,000 cubic meters, which amounts to over 40 million gallons, go over the falls every minute during peak season. That number lessens to about 110,000 cubic meters, or about 30 million gallons, per minute on average when averaging peak and non-peak seasons.

3,160 tons of water flow over Niagara Falls every second. This accounts for 75,750 gallons of water every second over the American and Bridal Veil Falls and 681,750 gallons per second over the Horseshoe Falls.
