Dam Memory! Who blew up a massive beaver dam in colonial Louisiana?

I remember learning in high school history that some guy blew up a huge beaver dam in the Louisiana region.
It was to get a route to the Atlantic from somewhere.

Google is just returning people blowing up beaver dams or beaver population info.
Trying to make polite conversation with my wife but the chick is asking for details and sources.

Thank You in advance!!

The Great Raft on the Big Bayou connecting to the Red to the Mississippi was blown up in the 1870s or 1880s.

This is a great story in Jefferson, Texas, even today.

Credit goes to Captain Shreve for clearing the raft. They named a town after him. There was an old meander of the Red called the Cane River that went around the old raft. Further down the Red, close to Alexandria, there was a low area that closed the Red River for about half the year. The Yankees almost lost a fleet here in the Civil War. Some diversions up the Red and a dry winter almost trapped the fleet.
