Manmade Flood Coming to Grand Canyon - washingtonpost.com: "PAGE, Ariz. -- Federal agencies are gearing up to release a manmade flood aimed at refreshing the ecosystem of the Grand Canyon.
A three-day torrent of water will be released from Glen Canyon Dam on the Arizona-Utah state line beginning Wednesday morning.
The Colorado River in the Grand Canyon downstream from the dam used to be warm and muddy. But the dam now traps silt and the river runs cold and clear through the canyon. The shift has helped speed the extinction of four fish species."
