The Frio River defines the drainage of this Frio County landscape, winding through a region marked by cattle ranching and water management infrastructure. This 2010 topographic survey documents the hydrological features essential to the local economy, including the Thompson Lake Dam and the Burns Reservoir Dam. The network of backroads and crossings, such as Paso De Piedra Rd and Martin Branch Rd, highlights the rural connectivity between scattered agricultural holdings. Tributaries like Lockhart Creek and Mule Creek feed into the primary river system, illustrating the natural watercourses that have historically dictated land use and settlement patterns in this part of South Texas.
