What Happened When Niagara Falls Was Turned Off?

In 1969, one of the most famous waterfalls in the world simply stopped. The U.S. Army Corps of Engineers dammed the Niagara River and diverted its flow away from the American Falls, leaving a dry, exposed cliff face where millions of gallons of water used to roar every second. In this episode of The Untold Ground, we look at why engineers made this decision, what the exposed riverbed revealed during the months it stood dry, and what the study ultimately concluded about the falls. The Untold Ground investigates real, verified historical events and discoveries tied to specific places. One place, one case file, one question that was never fully answered.
