About this map

Falcon Reservoir dominates this South Texas landscape, where the international boundary between Texas and Tamaulipas follows the submerged channel of the Rio Grande. The flooded landscape creates complex shorelines such as the Beckwith Arm, which extends into the brush country of Zapata County. While much of the area is inundated, the map preserves the names of features that define the shoreline and surrounding ranch lands, including the narrow Bronco Canyon and the isolated Juan Vela Lake to the east.

Evidence of local ranching infrastructure and remote access is found in the network of unpaved roads crisscrossing the arid terrain. Routes like Alejandrenas Rd and Cox Camp Rd provide a look at the rural connectivity required in this border region. The low-relief topography and seasonal drainage patterns are clearly marked, illustrating how the reservoir has reshaped the natural hydrology of the area.
