About this map

The Lapeyrouse Oil and Gas Field dominates the marshy landscape of Terrebonne Parish in the mid-1960s, reflecting the industrial footprint of petroleum extraction in the Louisiana wetlands. Numerous Gas Wells and drill holes are scattered throughout the inundated terrain, where the transition from solid land to open water is defined by a dense network of waterways. Water management and navigation are highlighted by the Bush Canal and the natural flows of Bayou Terrebonne and Bayou Petit Caillou.

Coastal geography is characterized by expansive bodies of water such as Lake Tambour and Lake Barre, joined by an intricate web of smaller bayous like Bayou Defrene and Bayou Charles Theriot. The area around Portage and Bay la Fleur illustrates the reliance on waterborne transport and seasonal activity in these brackish reaches before significant coastal erosion further altered the shoreline of the Gulf of Mexico.
