In the summer and fall of 1969, the American side of Niagara Falls stayed without water for 6 months. Researchers drained the falls to study the rock face. They were afraid it was going to become too unstable because of erosion. It took a 600 feet dam across the enormous Niagara River to really shut down these astonishing falls. This means they had to divert 60,000 gallons of water every second so that the remaining flow traveled over the biggest Horseshoe Falls. #brightside Animation is created by Bright Side. —————————————————————————————- Music by Epidemic Sound https://www.epidemicsound.com Check our Bright Side podcast on Spotify and leave a positive review! https://open.spotify.com/show/0hUkPxD34jRLrMrJux4VxV Subscribe to Bright Side: https://goo.gl/rQTJZz —————————————————————————————- Our Social Media: Facebook: https://www.facebook.com/brightside Instagram: https://www.instagram.com/brightside.official TikTok: https://www.tiktok.com/@brightside.official?lang=en Stock materials (photos, footages and other): https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru —————————————————————————————- For more videos and articles visit: http://www.brightside.me
