Niagara Falls: How American Falls could be turned off…again

New York State officials are considering turning off the American Falls, one of three waterfalls that make up the Niagara Falls, for several months in order to replace two old stone arch bridges, reported Buffalo news. Dewatering the American Falls would require the construction of a cofferdam spanning from the Goat Island to the US mainland in an effort to direct all the water to the Horseshoe Falls.
