2022 Map of Three Oaks

About this map

The tri-county junction of Wilson, Karnes, and Atascosa counties creates a unique convergence of administrative boundaries across this South Texas landscape. This rural terrain is characterized by a network of seasonal watercourses, including the winding Los Cortes Cr and Sulphur Cr, which drain into localized basins like Grimes Lake. The road network is primarily composed of ranch-to-market routes such as FM 541 and FM 1344, alongside numerous county roads like Co RD 207 and Co RD 214 that follow the property lines of large agricultural tracts. The presence of Tessman Lake and Tordillo Cr in the eastern and southern reaches highlights the subtle variations in the drainage patterns of this brush-country environment, where water remains the primary driver of both historical land use and modern infrastructure.
