1965 Map of Lopeno

About this map

The borderlands of South Texas along the Falcon Reservoir define this mid-1960s landscape, where the rising waters of the Rio Grande meet the industrial infrastructure of the Lopeño Gas Field. Small settlements like Lopeño and Falcon are positioned near the reservoir's edge, connected by the corridor of Route 83. The terrain is deeply etched by a network of ephemeral waterways including Arroyo del Tigre Grande, Arroyo del Tigre Chiquita, and Los Barrosos Creek, which drain toward the international boundary. A network of pipelines crisscrosses the brush country, servicing the local energy sector and converging near a Pumping Sta. The transition from Zapata County to Starr County is marked by a prominent Zapata Co Starr Co boundary line, illustrating the administrative and industrial organization of the Rio Grande Valley during this era of reservoir management.
