1932 Map of Lake Decade

About this map

Terrebonne Parish is defined by an intricate labyrinth of tidal waters and marshland in the early 1930s, where the influence of the Atchafalaya Bay meets a complex network of bayous. The landscape is dominated by expansive water bodies like Four League Bay and Lost Lake, separated by low-lying landforms such as Rice Island and Mosquito Island. This topography reflects the deltaic processes of South Louisiana before modern coastal erosion and significant canal dredging altered the shoreline. Human presence is sparse, marked primarily by remote outposts like Steinbergs Camp and various geodetic survey points like Tower and Mosquito. The map reveals a wild aquatic environment where named passages like Lost Lake Pass and Blue Bayou provided the primary means of navigation through the salt marshes and swamps.
