2019 Map of Derby

About this map

Derby serves as the primary focal point of this South Texas landscape, situated along the corridor that parallels the Interstate 35 path in Frio County. The terrain is defined by an intricate network of waterways, most notably the meandering Frio River and the Leona River, which converge in this area. These river systems, along with tributaries like Buck Cr and Live Oak Cr, dictate the movement of local ranch roads such as Derby Rd and FM 1581. The prevalence of water-management features like Cude Tank and Chapote Tank underscores the importance of water storage in this semi-arid ranching country. Researchers can trace the legacy of local land ownership and movement through family-named routes like Guajardo Rd, Beever Ln, and Siller Rd, which connect the scattered holdings across the brush country and Panther Hollow.
