Restoring A River

Forty years after one generation dammed the Colorado River at the upper end of the Grand Canyon, a new generation of engineers and scientists is struggling to deal with the consequences... To solve such problems, the engineers and scientists charged with managing the river have evolved a new approach: instead of trying to conquer nature, they are bold enough to think they can outfox it. Using a process called adaptive management, they hope to stave off or reverse damage done to the river and its life forms by manipulating flows from the dam."
