Overview: Niagara Falls, p. 58

These falls are famous because of their volume and height, although they are not the tallest in North America. The original reason for settlement at the falls was for hydroelectric power production that made Niagara and Buffalo one of the early industrial centers in New York. In fact, the falls are now carefully managed to allow maximum visual water effect in the day but to divert large amounts of water for power production at night.
