The federal government began unleashing a two and a half day flood through the Grand Canyon Wednesday in an attempt to improve the habitat for endangered fish. It's the third artificial test flood in the past 12 years, but some say the experiment doesn't go far enough.
The floods aim to recreate the flow of the Colorado River before Glen Canyon dam was built, when spring runoff would send torrents of muddy water through the Canyon. Environmentalists and even some federal officials say that one flood isn't going to make a difference, however. They are accusing the government of pushing the current test forward simply as a measure to maximize hydropower revenue.
Daniel Kraker of member station KNAU reports from the banks of the river in Page, Ariz., where twin torrents of water spouted from the dam at a rate of 300,000 gallons per second.
