Falcon Reservoir dominates the western landscape of this Zapata County region, where the Rio Grande's waters branch into numerous named arroyos. This hydrologic network includes Arroyo Veleno, Arroyo Humaran, and Arroyo Torcido, illustrating the drainage patterns into the massive international reservoir. The land is marked by traditional Texas ranching features, specifically numerous "tanks" or stock ponds such as Maestro Tank, Ranchito Tank, and El Medio Tank.
