Congress authorizes the restoration of the Kissimmee River ecosystem, which had been degraded by dredging and channelization beginning in the 1960s. This nearly $1 billion project was sponsored by the Corps and the SFWMD and sought to restore more than 40 square miles of historic oxbows and flood plain. As of 2018, the project is more than 90% complete and the Corps has determined that the project has surpassed expectations in many respects.
