It's the biggest operation of its kind in US history, as the state tries to save its coastline which is vanishing at an alarming rate.
We travel to the Mississippi River and the city of New Orleans to see how billions of dollars are being spent to fix the rapid land loss.
The project to revert the Mississippi to its land-making pathways could restore ecosystems destroyed by the Deepwater Horizon oil spill and create buffers to protect against sea level rise and hurricanes.
The Louisiana coastline is disappearing due to human-made and natural factors, such as leveeing the Mississippi for oil and gas infrastructure, erosion, and sea-level rises.
And this is having an impact on local wetlands which are eroding, leaving communities vulnerable to storm surges and flooding.
