About this map

Lapeyrouse Oil and Gas Field defines the industrial footprint of this coastal Terrebonne Parish landscape, where intricate marshlands meet the open waters of the Gulf of Mexico. Surveyed in the mid-1960s with revisions in the late 1970s, the map reveals a complex hydraulic network of natural bayous and man-made channels like Bush Canal that facilitate energy extraction and navigation. The transition from terrestrial marsh to expansive bays is evident in the transition between Bayou Terrebonne and Lake Barre.

Resource extraction infrastructure is prominently marked, with several Gas Wells and a Drill Hole situated near Bay la Fleur. These sites are linked by a fragile geography of named waterways such as Bayou de Mangue, Bayou Charles Theriot, and Petit Caillou Bayou. The land-water interface is further characterized by the Portage and numerous islands, showing the deltaic environment before significant modern coastal erosion altered these specific shorelines.
