Millions of Gallons Used to Flush Grand Canyon

"Man-Made Flood Planned for Grand Canyon" FOXNews (February 27, 2008)

The big flush is happening now, and will be for three days.

I'll be back, shortly, to update.

Glen Canyon Dam (finished 1963) created Lake Tahoe, and generates power. Lots of power. It also has interfered with the ecology of the Grand Canyon. Without seasonal changes in the Colorado River's flow, plants and animals that live there are having trouble surviving, like the humpback chub.

That's where the big flush comes in.

The official reason:
"Our ultimate purpose is to learn whether or not this is a viable strategy for creating sandbars and habitats for native fish," said John Hamill, chief of the Grand Canyon Monitoring and Research Center, part of the U.S. Geological Survey. They've tested this before, in 1996 and 2004.

It's all a plot, of course:
The Grand Canyon Trust sued the government last year, for not doing something.
Now: "They're trying to make it appear that they're doing something beneficial when they're just doing it for appearances," the Grand Canyon Trust's senior director, Nikolai Lash, said. "It's being manipulated to be a 'one and done,' even though we know that doesn't work."

I've got a better one:
The whole 'saving the chub' is just a cover for a vast government cover-up. An alien spacecraft was shot down in 1995. The wreckage came down in the Grand Canyon. These controlled floods of the Colorado are an effort to hide the evidence before the Galactic High Marshal arrives to investigate. (Do I believe this? Certainly not! But you gotta admit that it's not bad, for a conspiracy theory.)
