About this map

Coastal marshlands and industrial extraction define this Jefferson County shoreline during the early 1960s. The landscape is dominated by a complex network of brackish water bodies, including Clam Lake, Salt Lake, and the expansive Gulf of Mexico. The Intracoastal Waterway cuts a straight path through the northern marshes, facilitating maritime commerce while smaller artificial channels like Tenmile Bayou (Cut) and Salt Bayou (Cut) navigate the wetlands to the south.

Petroleum production is central to the area's development, anchored by the Clam Lake Oil Field and scattered Oil Wells. Human settlement is sparse, represented by small coastal outposts at Fadden and Rebecca along State Route 87. The presence of Dipping Vat Ponds suggests a history of livestock management in these coastal flats, while features like Fence Lake and Wiseman Lake mark the transition from the wet interior to the sandy Gulf coast.
