Don't say an engineer, that it cant be done.

Well who hoped that, Niagara Falls could also be shut down.

Back in 1969, when American and Canadian Government decided to shut down the Niagara falls, to check for continued slides, that cause the falls to completely erode. Therefore it was decided to shut down the Niagara Falls for 5 months to check for Erosion.

It took around 3 days, 1200 trucks to dump 28000 tons of fill into an upstream area of Niagara Falls. There were many suicide attempts at Niagara Falls, but to everyone shocking only 2 corpses were found. 

Sharing some pics of Niagara Falls when it was shut down.
