Alamo and the surrounding irrigated plains of the Rio Grande Valley appear here during a period of significant residential expansion. The landscape is defined by an intricate network of colonias, ranging from established communities like North Alamo Village Colonia to smaller residential pockets such as Tierra Bonita Number 1 Colonia and Colonia Guadalupe. This 2010 survey illustrates the region's reliance on water management, anchored by Donna Reservoir 1 and Donna Reservoir 2, which are essential for both local agriculture and the growing population centers.
