1955 Map of La Leona

About this map

Arroyo City and the winding Arroyo Colorado anchor this landscape in coastal Cameron County, showing the complex water management systems of the mid-20th century. The map illustrates a transition from the agricultural operations of La Leona Ranch and Rancho Nuevo to the preserved wetlands of the Laguna Atascosa National Wildlife Refuge. Traces of local heritage are preserved at the La Leona Cem, located south of the Fernando East Road. The terrain is defined by a network of drainage features, including the North Floodway and Cayo Atascoso, alongside numerous named stock tanks like Los Patos Tank and Jasper Tank. This survey, revised in 1955 with 1980s updates, documents the essential infrastructure of South Texas ranching and water control, from the Pilot Channel to the many levees and ditches that shaped the coastal prairie.
