265.5 LBD St Francisville Mat Casting Field

Operated by the Army Corps of Engineers, the St Francisville Mat Casting Field is a 210 acre field in which the concrete squares that make up the “articulated mattresses” used to stabilize the river’s banks are cast and stockpiled.

Much of what was once the town of Bayou Sara is now taken up by the Mat Casting Field.
