More than 300,000 gallons of water per second was released from the Glen Canyon Dam into the Grand Canyon today.
This man-made flood is made to simulate natural ones that used to nourish the Grand Canyon's ecosystem:
"This gives you a glimpse of what nature has been doing for millions of years, cutting through and creating this magnificent canyon," Secretary of the Interior Dirk Kempthorne said after he pulled the lever releasing the water from the Glen Canyon Dam.
More than 300,000 gallons of water per second were being released from Lake Powell above the dam near the Arizona-Utah border, enough water to fill the Empire State Building in 20 minutes, Kempthorne said.

Huh?
I thought the Grand Canyon was about 4,000 years old and was created when the water drained away after the Great Flood.
