Grand Canyon Flooded

Floodwaters rushed through the Grand Canyon March 5. Millions of gallons released on purpose, U.S. officials say, to flush out the great gorge...forcing healthy Colorado River sediment through the ecosystem.

Environmentalists argue that one big flush is not enough to restore the river...a marine habitat that's gone downhill since the dam was built to generate hydroelectric power in 1963.
