The Mississippi River isn’t nearly as muddy as it used to be, and that could be bad for Louisiana coastal restoration. According to a recent article written by nola.com, “A new study indicates the concentrations of sediment in the lower Mississippi River have decreased by more than half in recent decades. That’s not good for Louisiana, which depends on a constant supply of river silt, sand and mud to rebuild land on its ever-eroding, ever-sinking coast.”
Although this is devastating news for coastal restoration warriors around Louisiana, there are many who are prepared for what this new study shows. The article written by nola.com also reveals, “The Mid-Barataria and Mid-Breton diversions the state Coastal Protection and Restoration Authority (CPRA) plans to build in Plaquemines Parish would channel sediment-rich water from the Mississippi into estuaries and bays that have been starved of sediment by the river’s levee system. The two diversions, which would cost a combined $2 billion, are expected to restore marshes lost to erosion, subsidence and sea level rise.”
