1956 Map of Progreso
USGS Topo · Published 1959About this map
The Rio Grande meanders along the southern edge of this mid-century survey, defining the international boundary and the intricate hydrology of the Rio Grande Valley. Irrigation and flood control dominate the landscape, visible through the Main Floodway, Llano Grande North Floodway, and the massive Mercedes District Settling Basin. The settlement of Progreso serves as a local hub near the Progreso Bend, where a U.S. Customs & Immigration station marks the crossing point.
