1979 Map of Zapata NW

About this map

Rio Grande Rio Bravo flows along the international boundary between the United States and Mexico, marking a landscape defined by the expansive Presa Falcon Reservoir. This late-1970s survey captures the riparian environment of Zapata County as it transitions from the river's path into the inundated reaches of the reservoir. Scattered ranching settlements and small locales such as El Ramireno and La Esperanza dot the brushy terrain, while the Old Ramireno Cem remains a significant marker of early regional history near the water's edge. The presence of several Gasoducto lines indicates the importance of energy infrastructure in this border region, crossing a landscape where traditional place names like Los Corrales and San Rafael persist alongside the modern management of the Rio Grande. Navigation buoys, including Buoy 33 and Buoy 26, delineate the jurisdictional waters near Jara China, reflecting the dual-national oversight of this hydrological system.
