1965 Map of Sagunada Ranch

About this map

Sagunada Ranch and La Brisa Ranch anchor this mid-1960s landscape in Starr County, where the brushland of South Texas gives way to a dense network of petroleum extraction. The terrain is defined by a series of prolific energy reservoirs, including the Barbacoas Oil Field, Ross Oil Field, and the Janal Gas Field. These industrial zones are connected by numerous pipelines and access roads that crisscross the drainage of Olmitos Creek and Garcias Creek. Water management is evident through the presence of several engineered structures like Dam No 3 and Dam No 4, alongside a Flowing Well in the south. This survey illustrates the transformation of traditional ranching land into a highly developed industrial corridor, where specialized features like a Substa, Pumping Sta, and even a dedicated Landing Area support the region's energy economy.
