"In the 1960s, a group of businessmen bought 16,000 acres of swampy bottomland along the Ouachita River in northern Louisiana and built miles of levee around it. They bulldozed its oak and cypress trees and, when the land dried out, turned it into a soybean farm.

Now two brothers who grew up nearby are undoing all that work. In what experts are calling the biggest levee-busting operation ever in North America, the brothers plan to return the muddy river to its ancient floodplain, coaxing back plants and animals that flourished there when President Thomas Jefferson first had the land surveyed in 1804."
