To control flooding, the Kissimmee River was straightened from 1962 to 1970. While the project delivered on the promise of flood protection, it also destroyed much of a floodplain-dependent ecosystem that nurtured threatened and endangered species, as well as hundreds of other native fish and wetland-dependent animals. More than 90 percent of the waterfowl that once graced the wetlands disappeared and the number of bald eagle nesting territories decreased by 70 percent. After the waterway was transformed into a straight, deep canal, it became oxygen-depleted and the fish community it supported changed dramatically. It is expected to be completed in 2011.
