The study area included in the Barataria and Terrebonne Bays vignette of
southeastern Louisiana spans eastward from Terrebonne Bay to Barataria Bay (Figure 1)
and includes portions of Terrebonne, Lafourche, St. Charles, Jefferson, Orleans,
Plaquemines, and St. Bernard Parishes. This area falls between the Mississippi River on
the east and northeast, extends down through the western shore of Lake Salvador and the
Dixie Delta Canal, then runs west to Houma and follows Louisiana Route 315 to the
coast; Barataria and Terrebonne Bays are separated from each other by Bayou Lafourche.
