Assignment
We are going to take a hard look at the Mississippi River and delta as an introduction to our discussion of flood law and adaptation. The key fact about the Louisiana coast is that it is very flat and very low. Review this map to get a sense of the elevation of coastal Louisiana. Focus on the red areas, which are less than 5 foot above sea level:
The story of Louisiana is the story of trying to control the Mississippi and exploit the delta. A key piece of this is the problem of keeping the Mississippi from changing courses and stranding Baton Rouge and New Orleans, which becomes more likely with climate change.
Find the Old River Control Structure on Google Maps and look at it and the river from a satellite view, then follow down the Atchafalaya floodway to Morgan City to see where the water would go if the structure fails.
Read: John McPhee, Atchafalaya, New Yorker (1987) (pdf version)
McPhee is one the top living nonfiction writers. This is his New Yorker article on flood control on the lower Mississippi and New Orleans, with a focus on the Old River Control Structure. It is a fascinating blend of science and history and is very well written.
