One of 36 families in Montz whose houses were appropriated by the U.S. Army Corps of Engineers in 1973 for construction of a new levee.

The Bonnet Carré Crevasse occurred in and near the present-day location of Montz. It was one of several levee breaches in the Bonnet Carré area in the mid-to-late-1800s.[1] Bonnet Carré was approximately 50 kilometers from New Orleans, Louisiana.[2] The breach occurred when excess water from the Mississippi River flowed over the east bank levee of Bonnet Carré.

Montz is located between LaPlace, Louisiana and the Bonnet Carré Spillway. It was separated from the other municipalities and communities on the east bank of the Mississippi River in St. Charles Parish by the construction of the spillway, which was completed in 1931.
