The Rio Grande forms a winding international border on this south Texas survey, defining the southern limit of Donna and Weslaco. This landscape is heavily shaped by water management systems essential for Rio Grande Valley agriculture, including the prominent Donna Main Canal and the Main Floodway that cuts across the central terrain. The map serves as a valuable resource for genealogists, as it identifies several family and community burial sites scattered throughout the rural and suburban fringe, such as Webber Cem, Handy Cem, Asadores Cem, and Balli Cem. In the northeast, the residential development of Tierra Santa sits near the headwaters of the Arroyo Colorado, illustrating the continuing expansion of these Hidalgo County communities along the Mexican border.
