Bailey's Dam at Alexandria, Louisiana

From Wikipedia.

In the last post I wrote about Bailey's Dam which resulted in the saving of Admiral Porter's fleet during the Red River Campaign when it raised the river's water level high enough for the ships to pass through some very shallow water.

The site was listed on the NRHP in 1976.  Remnants of it could be seen at low water until 1987 when the United States Corps of Engineers completed the John Overton Lock and Dam downstream which flooded the site.

Before flooding it, however, the Corps sponsored archaeological excavations of it.
