Falcon Reservoir dominates the southwestern quadrant of this Zapata County landscape, where the rising waters of the Rio Grande meet a dense network of intermittent drainages. The area is defined by a system of arroyos that feed into the reservoir, including Arroyo Costa Rica, Arroyo Indio, and the prominent Arroyo Veleño. This hydraulic pattern reveals a terrain shaped by seasonal water flow, where named tanks like Hondo Tank and Maestro Tank provide critical water storage points across the ranchlands. North of the reservoir, the Zapata County Airport serves as a modern hub connected by Airport Rd, while the surrounding land is crisscrossed by ranching routes such as Jennings Ranch Rd and San Jose Rd. These roads and water features, including Salómoneno Cr and Villa Cr, delineate property boundaries and livestock access in a region defined by its proximity to the international border.
