2016 Map of Derby
USGS Topo · Published 2016About this map
Frio River and Leona River converge in this brush-country landscape of Frio County, where a network of ephemeral creeks and watering tanks defines the South Texas ranching economy. The settlement of Derby sits at the southeastern corner of the sheet, positioned along the vital transportation corridor of the I-35 Access Rd. The land is heavily divided by rural roads like FM 1581 and Derby Rd, connecting scattered agricultural resources such as Chapote Tank and Cude Tank. This 2016 survey highlights the significance of drainage patterns in this semi-arid region, tracing the winding paths of Buck Cr, Live Oak Cr, and Todos Santos Cr as they navigate the subtle shifts in elevation toward Panther Hollow.
