Deflecting The Water Elsewhere
For this to work, they had to first deflect the water over the American Falls. The plan was then put into action on November 13, 1966. They had to push the gates of the International Water Control Dam wide open to allow the current in.
Pushed Into Overdrive
Not only was the Dam pushed into overdrive, but the hydro generating stations were at complete capacity too. The water flowing over the falls was reduced to 15,000 gallons per second instead of its usual 60,000. Workers began clearing debris as the river receded.
