1956 Map of Telegraph Swamp NE

About this map

Rainey Slough dominates the northeastern landscape of this mid-century topographic study, illustrating the complex water drainage patterns of the South Florida interior. This 1956 planetable survey details a predominantly uninhabited wetland environment defined by numerous small ponds and cypress strands at the border of Charlotte Co and Glades Co. The map records a specific moment in the hydrological history of the region before significant modern drainage alterations, capturing the natural path of the Branch and the surrounding marshland. The terrain is notably flat, with elevations barely shifting more than a few feet across the sections, reflecting the characteristic low-lying geography that once defined much of the Caloosahatchee River watershed area.
