2016 Map of Arroyo Salado West

About this map

The Rio Grande serves as the prominent western boundary in this South Texas landscape, marking the international border between the United States and Mexico. This arid region in Zapata County is defined by a series of drainage systems and ranching infrastructure that speak to the managed water resources necessary for the local economy. Significant water features include Dolores Cr, which feeds into the larger Arroyo Dolores, and a chain of named impoundments including Jesse McNeel Lake Number 1 and various reservoirs associated with La Perla Ranch Lake Number 4. The terrain is characterized by the Arroyo Salado in the southern portion of the sheet, while highway 83 provides the primary north-south transit corridor through this borderland territory.
