Nature and fluid dynamics have their own way of doing things, and that's why rivers and streams left to their own devices will change over time. But those changes interfere with human settlements and commerce, so various aspects of the Mississippi River have been engineered one way or another ever since the US was established. This video from Half as Interesting tells us about the time riverboat captain Henry Miller Shreve arranged for a channel to be cut through a particularly difficult bend in the river to make navigation easier. But that cut changed the river's eventual direction so much that authorities added the Old River Control Structure to keep Old Man River from dumping all its water into the Atchafalaya River. The video is only 4:18; the rest is an ad.
However, several Louisiana commenters tell us that the tendency of the Mississippi to spill into the Atchafalaya was actually due to the clearing of the Great Raft, a 150-mile logjam in the Atchafalaya and Red River that had been there for a few thousand years and was responsible for the bayous. Who cleared that logjam? Why, it was Henry Miller Shreve, who just couldn't keep his hands off the waterways. Yes, Shreveport was named after him, since removing the raft made the Red River navigable. The Great Raft story would make a fascinating video. -via Digg

Bought a house with an underground (most of the time) river. Learned that redirecting it made me liable for any damage done by the resulting flow. Only option was to bury pipes to take it to the storm drains. Cannot imagine having to pay for the Mississippi’s damages.
