Plan would rebuild Louisiana coast with Mississippi River sediment

By on March 13, 2012

Louisiana’s coastline is disappearing under rising sea levels, but that could be halted or even reversed by a plan in the state’s legislature to change how the Mississippi River’s flow and sediment are managed, according to a report from the Los Angeles Times.

The plan calls for cuts in the decades-old levees built around New Orleans to protect the city from the river’s floods. The cuts would let the river carry more sediment to its mouth and replenish the delta’s islands that are now washing away.

Opponents of the plan worry that the additional flow of fresh water from the river would ruin economically important saltwater fisheries.
