"The Kissimmee: A River Recurved"

"It sounds almost superhuman to try straighten a river and then recarve the curves.

That's what federal and state officials did to the Kissimmee River in central Florida. They straightened the river in the 1960s into a canal to drain swampland and make way for the state's explosive growth. It worked — and it created an ecological disaster. So officials decided to restore the river's slow-flowing, meandering path.

That billion-dollar restoration — the world's largest — is a few years from completion. And so far, it's bringing signs of new life, especially on a man-made canal that was dug through the heart of the river."
