1936 Map of Santa Maria

About this map

The serpentine Rio Grande forms a complex international boundary in this 1929 survey of Cameron County, revealing a landscape defined by its ancient river channels and modern irrigation infrastructure. The map details numerous river bancos, such as Palma Banco No 25 and Soliseno Banco No 23, which are remnants of the shifting border between the United States and Mexico. Large-scale agricultural development is evident through the network of pumping stations, including the Santa Maria Pumping Sta and La Feria Pumping Sta, which drew water into the surrounding fields.
