About this map

Lake Penchant dominates this coastal landscape, reflecting the intricate hydrology of Terrebonne Parish in the mid-1960s. The map illustrates a complex network of waterways, including Bayou Penchant and Bayou Copasaw, which wind through marshy terrain and across Bleux Island. The integration of industrial infrastructure into this environment is evident through the presence of several pipelines and a designated gas field, showing how energy extraction was being mapped alongside natural features like Brady Bayou and Bois Mauvais Bayou.

The southern portion of the sheet features the broad expanse of Lake De Cade and the mouth of Turtle Bayou. These waters, along with Little Bayou Carencro and Bayou la Loutre, defined the local geography before subsequent coastal changes. This survey provides a baseline for understanding the fluid boundaries of Louisiana's wetlands, where every canal and drill hole represents a human imprint on the deltaic plain.
