This most recent discharge was the third of its kind. The first, in 1996, washed what little sediment there was downstream past the Grand Canyon and into Lake Mead. The second, in 2004, redistributed too little sand. Definitive results on the success of this last experiment should be available within the year and will serve as a guidepost for the next flow, which is as yet unscheduled.
LA Times reports that during the simulated flood there is reduced flow through the hydroelectric turbines. So what is the net carbon footprint for the water that is released? They also report a 10 year $80 million study before it was approved. That would pay for a lot of solar panel rebate checks.
Your missing the point. It's not about your "carbon footprint." It's about restoring an ecological system that man has destroyed. People are so wrapped on the hot air coming out of Al Gore's mouth that they forget about real issues.
Thats a great picture, but its better in the magizine.
If I calculated it correctly, that's an Olympic Pool spewing out of there every two seconds.
I also wonder how fast it's going...
