The «Glory Hole»

At 22 meters in diameter,the hole sucks in water from the dam to prevent flooding at a rate of 1,300 cubic meters per second when it reaches capacity . The water is carried through a large concrete pipe and emptied about 210 meters away . The «glory hole» (glory spillway) was only expected to be in action every 50 years, but extreme weather has ramped up its use to twice in 24 months. Thanks for watching the video.
