Falcon Reservoir and the Rio Grande define the international boundary between the United States of America and Mexico in this South Texas borderland. The landscape is characterized by a series of drainages, or arroyos, that feed into the reservoir, including Arroyo Leon, Arroyo Clareno, and Arroyo Loma Blanca. These waterways carve through a terrain dotted with small ranching settlements and local landmarks.
