2022 Map of Arroyo Salado West

About this map

The Rio Grande serves as the international boundary between the United States and Mexico, carving a serpentine path through the arid brushlands of Zapata County. This landscape is defined by the drainage patterns of seasonal creeks and arroyos, including the prominent Arroyo Salado and Dolores Cr, which feed toward the river valley. The presence of the Dolores Cem near the river's edge provides a significant point of interest for genealogists and local historians, anchoring the map to the region's ranching heritage. Ranching operations are further evidenced by water management features like La Perla Ranch Lake Number 3 and La Perla Ranch Lake Number 4, which illustrate the reliance on localized reservoirs in this southwestern Texas environment.
