“Dramatic satellite images show large deposits of sediment in coastal Louisiana, the receiving end of the massive flooding on the Mississippi River.

The sediment gush has a down and up side in region known for its seafood and delicate wetlands, a federal official said Friday.

The U.S. Geological Survey (USGS) and NASA recently provided the stark imagery of the sediment plumes to the U.S. Army Corps of Engineers and Louisiana to assist them with flood response.

“We live in historic times,” said Phil Turnipseed, director of the USGS’s National Wetlands Research Center in Lafayette, Louisiana.

The tan and brown plumes resulted from millions of gallons of sediment-laden freshwater rushing to the Gulf through spillways, river channels and levees.

A map on the USGS website allows users to call up the plumes and see flood data collected by government agencies.

The opening of the Bonnet Carre spillway caused a sediment plume in Lake Pontchartrain above New Orleans. Another plume resulted from the opening of the Morganza Spillway and flooding on the Atchafalaya River. The third is where the Mississippi River meets the Gulf of Mexico.”
