1980 Map of Arroyo Burro

About this map

Falcon Reservoir defines the southwestern edge of this landscape in Zapata County, where the rising waters of the Rio Grande reach into the brushy draws of South Texas. This 1980 survey captures a network of ephemeral drainage systems, or arroyos, that characterize the ranchland terrain. Notable among these are Arroyo Burro, Arroyo Blanco, and Cavasara Creek, which cut through the arid plains toward the reservoir. Human activity is marked by scattered infrastructure typical of the region's ranching and industrial history, including the Refugio Ramirez Tank, a local Gravel Pit, and various isolated well sites. The terrain is further distinguished by features such as Cañada Las Palomas and Arroyo Rosita, illustrating how local naming conventions have long relied on these vital, if seasonal, watercourses to navigate the South Texas brush country.
