No not a joke - The CAN actually turn off Niagara Falls:

(Yep – it is now possible to “turn off” Niagara Falls, though I wouldn’t try it if I were you.)
The way they “turned off” the water was genius in its simplicity; they built cofferdams, which temporarily diverted all the water from the American Falls to the neighbouring Horseshoe Falls on the Canadian side. It was no small undertaking – 27,800 tons of rock and earth were used to build the cofferdams. Once the American Falls were reduced to a trickle, news spread and large crowds of locals and tourists gathered to catch a glimpse from the vantage point of Goat Island.
