About this map

Big Constance Lake and its surrounding marshlands dominate this 1932 coastal survey of Cameron Parish. Compiled by the U.S. Geological Survey using aerial photographs from the Army Air Corps, the map captures the intricate hydrology of the Louisiana shoreline before significant modern modification. The drainage pattern is defined by Constance Bayou and its smaller counterpart, Little Constance Bayou, which thread through the wetlands to meet the Gulf of Mexico. The shoreline itself is rendered with fine detail, showing the narrow barrier between the open sea and interior waters like Little Constance Lake. This advance sheet represents an early application of aerial photogrammetry in mapping the Gulf Coast, providing a precise record of the natural land lines and tidal features as they existed in the early 1930s.
