About this map

Morales-Sanchez and the adjacent Morales-Sanchez Colonia anchor the western edge of this South Texas landscape, where the seasonal drainage systems of Zapata County dictate the patterns of human activity. The terrain is defined by an intricate network of arroyos, most notably Arroyo Miguel and Arroyo Correhuela, which channel water toward numerous man-made and natural catchments. These water features, including Correhuela Tank, Tierra Blanca Tank, and the larger Lopez Lake, suggest a ranching economy reliant on these carefully placed reservoirs.

Water security in this arid environment is further evidenced by named landmarks like Charco Redondo Spring and Quemada Corral Tank. The road network is sparse, centered on FM 2687 and rural tracks like Huisache Ranch Rd, which connect remote tanks and ranching outposts. This survey provides a clear view of the complex hydrography of the Arroyo del Tigre Grande and Arroyo Salado basins before they join larger systems to the south.
