About this map

The Sabinal River and Frio River converge in this corner of South Texas, defining a landscape where multiple county lines—Uvalde, Zavala, Medina, and Frio—all meet. The drainage network is dense with smaller seasonal waterways, including the descriptively named Fight and Holler Cr, Blanco Cr, and Elm Cr.

Ranching and land management are evident through the numerous man-made water catchments like Gross Tank and Catfish Tank, which serve as vital landmarks in this arid brush country. Transportation is anchored by Ranch Rd 187 and Ranch Rd 140, providing the primary corridors for moving through these vast holdings. This 2022 survey captures the contemporary layout of these large properties and the natural hydrology that continues to shape land use across these four counties.
