About this map

The Rio Grande serves as both a literal and geopolitical boundary on this map, separating Fabens, Texas, from the northern reaches of Chihuahua, Mexico. The landscape is defined by an intricate network of irrigation and drainage infrastructure essential to the Rio Grande Valley's agriculture, including the Fabens Waste Channel, Island Drain, and various laterals like the Hansen Lateral. The settlement of Isla is situated among these waterworks, north of the international border.

Transport and land management are evident through the numerous rural routes and family-named landmarks such as Jess Harris Rd and RC Elam Rd. Near the Guadalupe Bridge, the complex hydrology of the Border Spur Drain Number One and Border Spur Drain Number Two highlights the engineering efforts required to manage the floodplain. This map provides a clear record of the international crossroads and the hydraulic systems that sustain the local economy.
