About this map

The irrigated landscape of Hidalgo County is defined by an intricate network of water management and energy extraction just north of the border in the early 1960s. San Carlos and La Blanca serve as central nodes for the surrounding agricultural tracts, linked by the Southern Pacific railroad line that cuts horizontally across the territory. This rail corridor supported industrial hubs like Elsa, where a refinery, substation, and filtration plant indicate a developed infrastructure for processing and distribution.

Energy production is a dominant feature of the terrain, with the San Salvador Gas Field and San Carlos Gas Field dotted with numerous gas wells. Water control is equally vital to this South Texas environment, managed through the Donna Main Canal and the Santa Cruz Canal. Smaller communities such as Evergreen and Engleman Gardens are situated amidst these intersecting utility lines and canals, illustrating the mid-century transition of the Rio Grande Valley into a highly engineered industrial-agricultural zone.
