Shaping Niagara Falls: Engineers, Hydropower, and Sustainability
Last month marked the 50th anniversary of turning off the American Falls, the smaller of the main cataracts at Niagara Falls. In the 1950s, engineers had replumbed the much larger Horseshoe Falls, shrinking it and diverting the majority of the water before it plunged over the precipice. All this may not seem very “green” — but the point was primarily to funnel water to hydropower stations. Thus, the modern history of Niagara Falls raises some interesting questions about what sustainability looks like in the Great Lakes basin.
