Why Did Engineers Shut Down Water Flow To Niagara Falls?

To find dead bodies? Is this true?

The 1960's was a time of free love, social justice, experimentation and cultural explosion. For Upstate New York, the summer of 1969 will always be remembered for the disaster that was the Woodstock Music Festival. However, just a few short hours north of that mud pit, another iconic even was making history. 

Over 40 years ago, U.S. engineers diverted the flow of the Niagara River away from the American side for several months. In 2010, these previously unreleased photos were made public. 

With yet another Niagara Falls diversion coming in the near future, let's revisit this momentous feat of engineering back in the "swinging sixties." It's not going to be all dead bodies and coins though. Scientists sought out to study the riverbed underneath the falls in hopes to slow down the erosion that was escalating on the American side of the falls. 

You always knew Niagara Falls as a consistent flow of power, rushing water but these pictures will reveal a new side to the falls you've never seen before.
