The Mississippi River Delta formed over thousands of years as North America’s mightiest river deposited sand, silt and clay into the warm waters of the northern Gulf of Mexico. Over the last few hundred years, human alterations of the river system have contributed to the delta’s collapse.

A 3.5-kilometer-long canal will carry sand and muck from the muddy river into the bay, helping rebuild vast wetlands eroded by sinking land and rising seas.
From restoring wetlands to advocating for state policies like Ohio’s H2Ohio and federal programs including the Great Lakes Restoration Initiative, our Audubon Great Lakes office is ensuring that safe and clean water runs throughout the Mississippi River into the Gulf of Mexico.
23 Μαρ 2007 · Currently, about two-thirds of flow is discharged via the lower Mississippi directly to the Gulf and one-third is discharged via the Atchafalaya River to a shallow bay where a new delta is forming. The location of levees is shown on the lower river as well as the location of the MRGO.

Delta formation was enhanced by a hierarchical series of forcing functions acting over different spatial and temporal scales during a period of stable ...
The Gulf of Mexico region has benefited enormously from Ocean Conservancy’s relationships with partners so deeply committed to improving ocean health. We especially offer thanks to the Walton Family Foundation for its long-standing support in the region, as well as its recent grant to help restore the Gulf in the wake of the BP oil disaster.
