Electric generator at Niagara Falls produces its first power

Niagara Falls is a group of three waterfalls at the southern end of Niagara Gorge, spanning the border between the Canadian province of Ontario and the U.S. state of New York. The largest of the three is Horseshoe Falls, which straddles the international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls lie within the United States. Formed by the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls have the highest flow rate of any waterfall in North America that has a vertical drop of more than 50 m (164 ft). During peak daytime tourist hours, more than 168,000 m3 (5.9 million ft3) of water goes over the crest of the falls every minute.
