The Rio Grande meanders along the international boundary between United States and Mexico, carving out a landscape defined by sharp oxbows and traditional water management. Surveyed in 1929, this sheet reveals the critical irrigation infrastructure of Cameron County, including the Santa Maria Pumping Plant and the La Feria Pumping Plant along the riverbank. These facilities supported the agricultural development of the Lower Rio Grande Valley, linking the river to the interior settlements of Santa Maria and Bluetown.
