2022 Map of Arroyo Burro

About this map

Falcon Reservoir reaches into the southwest corner of this South Texas landscape, where the ephemeral drainages of Zapata County carve a complex network of arroyos through the brush country. The eponymous Arroyo Burro dominates the southern drainage pattern alongside Las Palomas Cr, while the northern reaches are defined by Arroyo San Francisco and Arroyo Blancas. This modern survey reveals a sparsely populated ranching environment where water management is critical, evidenced by landmarks like the Refugio Ramirez Tank. Beyond the lone corridor of FM 3169, the terrain is marked by traditional place names such as Cañada Rosias and Arroyo Javelina, reflecting the enduring geography of the Rio Grande Valley hinterlands.
