What If the Mississippi River Changed Course?

One concrete structure in the middle of Louisiana is stopping America's biggest river from taking a shortcut to the sea — and leaving Baton Rouge and New Orleans behind. In this episode we follow the Mississippi from Minnesota to the Gulf, see why river deltas "jump" roughly every thousand years, and look at the Old River Control Structure, built in 1963 to stop the river from switching into the Atchafalaya — and how it nearly failed in the 1973 flood. Then we imagine the worst case: what would happen to Morgan City, New Orleans, the drinking water, the petrochemical corridor, the ports and America's grain exports if the river won? Plus the problems already here: land loss, record low water and saltwater wedges. ⚠️ This is a hypothetical, educational scenario.
