1946 Map of Lake La Graisse

About this map

Bayou Terrebonne cuts through the marshy landscape of southern Louisiana in this survey based on 1935 field work and aerial photography. The region is a complex network of coastal waterways and land grants, where drainage patterns and natural features dictate the geography of Terrebonne Bay. Prominent water bodies such as Lake Lagraisse, Lake Jean Pierre, and Lake Saint Jean Baptiste dominate the northern portion of the sheet, while the southern expanse transitions into the open waters of the Gulf. One notable interpretive detail is the presence of early 20th-century land grant lines, which are meticulously adjusted to follow natural features like Bayou Jose. These boundaries provide a glimpse into the division of coastal marshland before significant 20th-century erosion altered the shoreline. Features like Pt Meshe and Seabreeze Pass serve as vital landmarks for understanding the historical coastal morphology of this section of the parish.
