The marshy northern edge of Lake Pontchartrain reveals a complex network of coastal infrastructure and natural waterways in the mid-1930s. Small coastal communities like North Shore and Howze Beach serve as focal points along the shoreline, connected to the interior by the Southern railroad line. The map captures a heavy reliance on hydraulic engineering, shown through a series of numbered drainage canals—from Canal No 1 to Canal No 9—that cut through the wetlands north of Grand Lagoon.
