2022 Map of Zapata NW

About this map

The Rio Grande marks the international boundary between the United States and Mexico in this corner of South Texas. This specific section of the border is defined by the expansive Falcon Reservoir, which submerged much of the traditional riverbank landscape when it was created. Historical traces remain on the Texas side, most notably the Old Ramireno Cem, a site of significant genealogical value for families with roots in the Zapata County area. The surrounding terrain is characterized by the dendritic drainage patterns of small, unnamed arroyos that feed into the reservoir, reflecting the arid brushland that historically supported ranching communities along the river's edge.
