A 12,600 ha (31,000 acre) hypereutrophic lake in central Florida is being restored by constructing a 2,020 ha (5,000 acre) wetland filter to remove suspended sediments and particulate nutrients. A conceptual design for the wetland was developed based on experience gained from a 211 ha (520 acre) experimental marsh flow-way. A final plan was selected from 18 alternative layouts using several environmental, engineering, hydraulic, and hydrologic criteria in the selection process. Field hydraulic experiments are planned to further refine the design.
