Identifying Alteration of Natural Flow Regimes to Assess Stream Health


With an EPA grant, the US Fish and Wildlife Service, the Louisiana Department of Environmental Quality exit EPAand The Nature Conservancy have begun the largest floodplain restoration project in the country in the Ouachita River Ouchita Restorewatershed. Blocked from the river by a levee for several decades as a viable floodplain, about 16,000 acres of the Mollicy Farms tract have been replanted with native trees, which will help prepare the land to accept floodwaters after a controlled levee breech. These efforts will mimic the river’s natural flood pattern, help filter harmful substances from its waters, and create a much-needed habitat for area wildlife. The benefits continue downstream, with fewer pollutants entering the Gulf of Mexico from the Mississippi River drainage basin. The project could become a model for future river restoration efforts. It will take many more such projects to restore benefits such as flood control, water filtration, sediment reduction, and increased wildlife habitat that come from natural floodplains.

To showcase your project, please contact Brad Lamb, NPS coordinator.
