Rare Footage: Niagara Falls WITHOUT water! (video)

Unless you've been living under a rock all your life, I'm sure you've heard of Niagara Falls... Located on the boarder of Canada and the US, this natural wonder was formed when the glaciers receded at the end of the last ice age over 12,000 years ago. It is estimated that more than 6 million cubic feet of water falls over the edge every minute in high flow and 4 million cubic feet on average. 
With that much water it is no question that Niagara Falls is the most powerful waterfall in North America... which makes these photos and video below intriguing to look at.  

The United States Army Corps of Engineers (USACE) – Buffalo District was tasked with the dewatering of the American Falls project in 1969. The Albert Elia Construction Company of Niagara Falls, New York was awarded a $445,412 contract to build and remove a 600 foot (183m) cofferdam from the mainland to the head of Goat Island in order to divert the water from the American channel.  In addition, they were required to clean the surface of the river bed, scale loose rock from the face of the Falls, and install a water spray system. a really poor quality video from 1969 of the 'dry' falls below...
