Congress passed the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in 1990. It funds wetland enhancement projects nationwide, designating approximately $50 million annually for work in Louisiana. The USGS Site contains a complete description of CWPPRA.

A couple of the most interesting of these projects are efforts to redirect a portion of the river's flow back into the marshes. These so called freshwater diversion projects are showing great promise in reviving target wetland areas. Garyville, Donaldsonville (200,000 cfs), Violet, Myrtle Grove diversions are under consideration.
