Agricultural development and the irrigation infrastructure of the Rio Grande Valley characterize this 1963 survey. The city of Donna serves as a central hub, flanked by Alamo to the west and Weslaco to the east. The landscape is defined by a grid of citrus groves and fields managed by the Main Canal and the extensive Donna Reservoirs. Transportation and industry follow the Missouri Pacific railroad line, which connects the primary settlements. To the south, the Main Floodway and La Cruz Resaca indicate the hydrologic management required for this fertile region. Beyond the town centers, localized settlements like Val Verde and Scissors appear alongside essential community landmarks such as Mt Zion Ch and the St Joseph Cem. The presence of the Alamo Gas Field and Edinburg East Gas Field further illustrates the diversification of the local economy during the early 1960s.
