1932 Map of Rio Hondo

About this map

Arroyo Colorado and the winding Resaca De Los Fresnos dominate this Lower Rio Grande Valley landscape during a period of significant agricultural and railroad expansion. The map illustrates a transition from traditional ranching, evidenced by the Las Yescas Ranch, to a structured grid of irrigation canals and roads supporting new rail-side settlements like Lantana and Lozano. The Missouri Pacific and Southern Pacific lines cross-hatch the territory, facilitating the growth of Rio Hondo and the outskirts of San Benito. Local social hubs are clearly marked, including the Mexican Christian Ch and rural education centers such as Las Yescas Sch and San Jose Ranch Sch. This 1929 survey highlights the intricate hydrology of the region, where the natural meanders of the resacas were being integrated into the developing water management systems of Cameron County.
