The Mississippi Is Trying to Leave — Engineers Have Stopped It Since 1963

The Mississippi River is still being held on a course it would not naturally choose. Near Old River in Louisiana, the Atchafalaya offers a much shorter, steeper route to the Gulf—and by the 1950s, engineers feared it could capture more and more of the Mississippi’s flow. This video follows the Old River Control Complex from the 1952 warning signs to its completion in 1963, the near-disaster of the 1973 flood, and the daily engineering that still holds roughly a 70/30 split today. Along the way, we look at the collapsing guide wall, the hidden scour beneath the Low Sill Structure, and why a full river switch could transform navigation, industry, freshwater access, and communities across southern Louisiana. 👉 Do you think the Mississippi can be controlled forever?
