About this map

Industrial extraction and tidal waterways define this section of the Louisiana marshlands during the mid-1960s. The landscape is dominated by the Deer Island Gas and Oil Field and the Gas and Oil Field on Bateman Island, marked by numerous drill holes, oil wells, and gas wells. These features represent the significant petroleum infrastructure that reshaped the coastal wetlands, accompanied by an extensive network of pipelines cutting through the soft terrain.

The Lower Atchafalaya River serves as the primary artery, connecting with the Shaffer Bayou Cutoff and the Penchant Bayou. The complex hydrography includes inland water bodies like Sweetbay Lake and Lake Gascha, while the boundary between St. Mary Parish and Terrebonne Parish remains marked as an indefinite boundary. This survey captures a moment before further coastal subsidence and channelization continued to alter these intricate bayou systems.
