2019 Map of Beckwith Arm

About this map

The international boundary between the United States of America and Mexico cuts directly through the waters of the Falcon Reservoir in this South Texas borderland. The landscape is defined by the labyrinthine shoreline of the Beckwith Arm, where numerous peninsulas and inlets create a complex interface between water and land. Several local roads, including Alejandrejas Rd, Cox Camp Rd, and El Tigre Rd, provide access to the remote fingers of land that extend into the reservoir. Further inland to the east, the terrain transitions into more arid brush country, marked by the drainage of Bronco Canyon and small bodies of water like Juan Vela Lake. The map illustrates the 21st-century state of this managed waterway and the network of access roads serving the Zapata County ranchlands.
