The Day They Turned Off Niagara Falls

Imagine visiting Niagara Falls and finding… no waterfall.
It sounds impossible, but in 1969, the United States Army Corps of Engineers carried out one of the strangest engineering projects in American history. To investigate dangerous rock erosion, they temporarily stopped the flow of the American Falls, leaving millions stunned.
For the first time in thousands of years, tourists witnessed an eerie sight: exposed rocks, a dry riverbed, and one of the world's greatest natural wonders completely transformed.
This documentary explores why Niagara Falls was shut down, the surprising discoveries made on the riverbed, and how engineers brought the falls back to life.
From shocking photographs to incredible engineering, this is the unbelievable true story of the day Niagara Falls disappeared.
