About this map

Lac des Allemands dominates this landscape, its expansive waters meeting the marshy edges of several South Louisiana parishes. This 2015 survey illustrates the complex hydraulic environment where natural bayous like Bayou Lasseigne and Bayou Portier intersect with man-made drainage systems. The map captures the distinct geographic points that define the lake's perimeter, including Fausse Pointe, Pointe aux Herbes, and Pointe Cypres.

Evidence of historical land use and early engineering is visible through the extensive network of named canals to the east, such as the Saint Charles Canal, Little Pecan Tree Canal, and Marys Canal. These waterways underscore the region's long-standing reliance on carefully managed drainage for agriculture and habitation. On the western shore, the presence of Rue St James marks the edge of settlement near the St. James Parish line, while Knights Bay Island sits as a notable landform within the lake's northern reaches.
