The mayor of New Orleans signed an emergency declaration over saltwater intrusion in the Mississippi River that is affecting water supplies in Plaquemines Parish. Weather forecasts suggest that river volume will drop to historic lows in the next several weeks.
An underwater sill was constructed to slow movement of the saltwater in July, but the barrier was overtopped, so additional work to expand the sill will be untaken to keep the saltwater downriver. It is thought that saltwater intrusion can be delayed by roughly 10 to 15 days.
